The contour can be any ``well-behaved'' curve in the sense that it is continuous, and that the points where the tangent is horizontal or vertical can be determined; the trajectory can be any spline curve. First a definition is given of generalized cylinders in terms of the Frenet frame of the trajectory. Then the main problem in ray tracing these objects, the computation of the intersection points with a ray, is reduced to the problem of intersecting two two-dimensional curves. This problem is solved by a subdivision algorithm. The three-dimensional normal at the intersection point closest to the eye point, necessary to perform the shading, is obtained by transforming the two-dimensional normal at the corresponding intersection point of the two two-dimensional curves.

They classify space into shells (bounding volumes), starting from the parent shell (the scene) to the leaf nodes (primitives). They divide processing into three major tasks which are easy to schedule and pipeline, and then define a processor called a PERT (Pipelined Engine for Ray Tracing) which can support these tasks and work either separately or in parallel. A powerful, flexible system. \\ New single- and multiprocessor models for ray tracing are presented. Important features are (1) the use of custom VLSI building blocks, (2) the use of a modified hierarchical data-structure-based ray tracing algorithm with three disjoint data sets, and (3) scene access through adaptive information broadcasting. A modular design is presented that permits incremental performance enhancement up to two orders of magnitude over conventional minicomputers or workstations.

A subset of these techniques generates images by computing 2-D projections of a colored semitransparent volume, where the color and opacity at each point are derived from the data using local operators. Since all voxels participate in the generation of each image, rendering time grows linearly with the size of the dataset. This paper presents a front-to-back image-order volume-rendering algorithm and discusses two techniques for improving its performance. The first technique employs a pyramid of binary volumes to encode spatial coherence present in the data, and the second technique uses an opacity threshold to adaptively terminate ray tracing. Although the actual time saved depends on the data, speedups of an order of magnitude have been observed for datasets of useful size and complexity.

Yet, only recently has there been any attempt at directly antialiasing spline curves. Parametric spline curves have resisted antialiasing in several ways: single segments may cross or become tangent to themselves. Cusps and small loops are easily missed entirely. Thus, short pieces of the curve cannot necessarily be rendered in isolation. Finding the distance from a pixel center to the curve accurately and efficiently---usually an essential part of antialiasing---is an unsolved problem. The method presented by Lien, Shantz, and Pratt [21] is a good start, although it considers pixel-length pieces of the curve in isolation and lacks robustness in the handling of certain curves.

When designing a graphic, BOZ aims to optimize two ways in which graphics help expedite human performance of information-processing tasks: (1) allowing users to substitute simple perceptual inferences in place of more demanding logical inferences, and (2) streamlining users' search for needed information. BOZ analyzes a logical description of a task to be performed by a human user and designs a provably equivalent perceptual task by substituting perceptual inferences in place of logical inferences in the task description. BOZ then designs and renders an accompanying graphic that encodes and structures data such that performance of each perceptual inference is supported and visual search is minimized. BOZ produces a graphic along with a perceptual procedure describing how to use the graphic to complete the task. A key feature of BOZ's approach is that it is able to design different presentations of the same information customized to the requirements of different tasks. BOZ is used to design graphic presentations of airline schedule information to support five different airline reservation tasks. Reaction time studies done with real users for one task and graphic show that the BOZ-designed graphic significantly reduces users' performance time to the task. Regression analyses link the observed efficiency savings to BOZ's two key design principles: perceptual inference substitutions and pruning of visual search.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", keywords = "Algorithms; Applications and expert systems; Artificial intelligence; Automated design; Computer graphics; Design; Ergonomics; experimentation; Graphic design; Graphic user interface; Human factors; Human information processing; Methodology and techniques; Models and principles; Software engineering; Task analysis; Theory; Tools and techniques; User interfaces; User/machine systems; Visual languages", subject = "{\bf H.5.2}: Information Systems, INFORMATION INTERFACES AND PRESENTATION, User Interfaces, Screen design. {\bf H.5.2}: Information Systems, INFORMATION INTERFACES AND PRESENTATION, User Interfaces, Interaction styles. {\bf H.1.2}: Information Systems, MODELS AND PRINCIPLES, User/Machine Systems, Human information processing. {\bf D.2.2}: Software, SOFTWARE ENGINEERING, Tools and Techniques, User interfaces. {\bf I.3.6}: Computing Methodologies, COMPUTER GRAPHICS, Methodology and Techniques, Ergonomics. {\bf H.5.2}: Information Systems, INFORMATION INTERFACES AND PRESENTATION, User Interfaces, Ergonomics.", } @Article{Klassen:1991:IFD, author = "R.

For instance, incorrect results can be obtained when the contours are not convex, or when the contours in two successive slices are very different. In the same way, the presence of multiple contours in a slice leads to ambiguities in defining the appropriate links. The purpose of this paper is to define a general triangulation procedure that provides a solution to these problems. We first describe a simple heuristic triangulation algorithm which is extended to nonconvex contours. It uses an original decomposition of an arbitrary contour into elementary convex subcontours. Then the problem of linking one contour in a slice to several contours in an adjacent slice is examined. To this end, a new and unique interpolated contour is generated between the two slices, and the link is created using the previously defined procedure. Next, a solution to the general case of linking multiple contours in each slice is proposed.

A {\em bounding function} in this context is an upper or lower estimate on the extent of the constituent sets; such bounds are commonly used to speed up algorithms based on such trees. We introduce the class of {\em totally consistent bounding functions}, which have the desirable properties of allowing surprisingly good bounds to be built quickly. Both outer and inner bounds can be refined using a set of rewrite rules, for which we give some complexity and convergence results. We have implemented the refinement rules for outer bounds within a solid modeling system, where they have proved especially useful for intersection testing in three and four dimensions.

This permits us to introduce a minimal set of generalized Euler operators, sufficient for the construction and manipulation of $r$-sets. The completeness result for ordinary Euler operators carries over immediately to the generalized Euler operators on the $r$-sets and the modification of the usual boundary data structures, corresponding to our extension to nonmanifold $r$-sets, is straightforward. We in fact describe a modification of a well-known boundary data structure in order to illustrate how the extension can be used in typical solid modeling algorithms, and describe an implementation.\par The results described above largely eliminate what has been called an inherent mismatch between the modeling spaces defined by manifold solids and by $r$-sets. We view the $r$-sets as a more appropriate choice for a modeling space: in particular, the $r$-sets provide closure with respect to regularized set operations and a complete set of generalized Euler operators for the manipulation of boundary representations, for graphics and other purposes.

In principle, it can be calculated precisely on a sufficiently well-calibrated display surface, but calibration is very expensive. Consequently, most current systems deal with contrast using heuristics. However, the usual CRT setup puts the display surface into a state that is relatively predictable. Luminance values can be estimated based on this state, and these luminance values have been used to calculate contrast using the Michelson definition. This paper proposes a method for determining the contrast of colored areas displayed on a CRT. It uses a contrast metric that is in wide use in visual psychophysics and shows that the metric can be approximated reasonably without display measurement, as long as it is possible to assume that the CRT has been adjusted according to usual CRT setup standards.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", keywords = "algorithms; human factors", subject = "{\bf I.3.3}: Computing Methodologies, COMPUTER GRAPHICS, Picture/Image Generation, Display algorithms. {\bf B.4.2}: Hardware, INPUT/OUTPUT AND DATA COMMUNICATIONS, Input/Output Devices, Image display. {\bf H.5.2}: Information Systems, INFORMATION INTERFACES AND PRESENTATION, User Interfaces, Screen design.", } @Article{Wu:1992:CQD, author = "Xialin Wu", title = "Color Quantization by Dynamic Programming and Principal Analysis", journal = j-TOG, volume = "11", number = "4", pages = "348--372", month = oct, year = "1992", CODEN = "ATGRDF", ISSN = "0730-0301 (print), 1557-7368 (electronic)", ISSN-L = "0730-0301", bibdate = "Fri Jan 5 07:58:42 MST 1996", bibsource = "http://www.acm.org/pubs/contents/journals/tog/; http://www.math.utah.edu/pub/tex/bib/tog.bib", URL = "http://www.acm.org/pubs/toc/Abstracts/0730-0301/146475.html", abstract = "Color quantization is a process of choosing a set of $K$ representative colors to approximate the $N$ colors of an image, $K < N$, such that the resulting $K$-color image looks as much like the original $N$-color image as possible. This is an optimization problem known to be NP-complete in $K$. However, this paper shows that by ordering the $N$ colors along their principal axis and partitioning the color space with respect to this ordering, the resulting constrained optimization problem can be solved in $O(N + KM^{2})$ time by dynamic programming (where $M$ is the intensity resolution of the device).\par Traditional color quantization algorithms recursively bipartition the color space. By using the above dynamic-programming algorithm, we can construct a globally optimal $K$-partition, $K>2$, of a color space in the principal direction of the input data. This new partitioning strategy leads to smaller quantization error and hence better image quality. Other algorithmic issues in color quantization such as efficient statistical computations and nearest-neighbor searching are also studied. The interplay between luminance and chromaticity in color quantization with and without color dithering is investigated.

The performance of CIE 1931 XYZ, CIELUV, CIELAB, YES, CCIR 601-2 YCbCr, and SMPTE-C RGB is measured against these requirements. With extensions, all of these spaces can meet the first two requirements. Quantizing error dominates the representational errors of the tested color spaces. Spaces that offer low quantization error also have low gain for image noise. All linear spaces are less compact than nonlinear alternatives. The choice of nonlinearity is not critical; a wide range of gammas yields acceptable results. The choice of primaries for RGB representations is not critical, except that high-chroma primaries should be avoided. Quantizing the components of the candidate spaces with varying precision yields only small improvements. Compatibility with common image data compression techniques leads to the requirement for low luminance contamination, a property that compromises several otherwise acceptable spaces.

Considering the pixels as square regions of the plane, a ``correct'' algorithm should paint those pixels whose centers lie at less than half the desired line width from the curve. A straightforward implementation, scanning the display array evaluating the Euclidean distance from the center of each pixel to the curve, is impractical, and a standard quad-tree-like recursive subdivision scheme is used instead. Then we attack the problem of testing whether or not the Euclidean distance from a point to an implicit curve is less than a given threshold. For the most general case, when the implicit function is only required to have continuous first-order derivatives, we show how to reformulate the test as an unconstrained global root-finding problem in a circular domain. For implicit functions with continuous derivatives up to order $k$ we introduce an approximate distance of order $k$. The approximate distance of order $k$ from a point to an implicit curve is asymptotically equivalent to the Euclidean distance and provides a sufficient test for a polynomial of degree $k$ not to have roots inside a circle. This is the main contribution of the article. By replacing the Euclidean distance test with one of these approximate distance tests, we obtain a practical rendering algorithm, proven to be correct for algebraic curves. To speed up the computation we also introduce heuristics, which used in conjunction with low-order approximate distances almost always produce equivalent results.

NURBS have become a de facto standard in commercial modeling systems because of their power to represent free-form shapes as well as common analytic shapes. To date, however, they have been viewed as purely geometric primitives that require the user to manually adjust multiple control points and associated weights in order to design shapes. Dynamic NURBS, or D-NURBS, are physics-based models that incorporate mass distributions, internal deformation energies, and other physical quantities into the popular NURBS geometric substrate. Using D-NURBS, a modeler can interactively sculpt curves and surfaces and design complex shapes to required specifications not only in the traditional indirect fashion, by adjusting control points and weights, but also through direct physical manipulation, by applying simulated forces and local and global shape constraints. D-NURBS move and deform in a physically intuitive manner in response to the user's direct manipulations. Their dynamic behavior results from the numerical integration of a set of nonlinear differential equations that automatically evolve the control points and weights in response to the applied forces and constraints. To derive these equations, we employ Lagrangian mechanics and a finite-element-like discretization. Our approach supports the trimming of D-NURBS surfaces using D-NURBS curves. We demonstrate D-NURBS models and constraints in applications including the rounding of solids, optimal surface fitting to unstructured data, surface design from cross sections, and free-form deformation.

A failing of forward differencing is the tendency to generate many extraneous points for curves with highly nonuniform parameterizations. A key result is presented and proven, namely, that a few levels of subdivision, prior to initialization for forward differencing, can improve substantially the quality of the step size estimate, resulting in very few extra points. The initial subdivisions can be done without loss of the exact integer precision available in forward differencing. For small numbers of points---a common occurrence in fonts---exact subdivision is even faster than exact forward differencing. When exact subdivision is used in conjunction with a previously presented exact forward-differencing algorithm, arbitrary cubic curves may be rendered with 32-bit arithmetic and guaranteed single-pixel accuracy, in a grid with an address space as large as 0..7281, with no two generated points greater than one pixel apart. This is more steps than previously possible. Previous discussions of rendering using subdivision have concentrated not on distance but on straightness estimates, whereby subdivision can be stopped once a subcurve can be drawn safely using its polygonal approximation. In this article, bounds are also derived on the size of the control polygon after multiple levels of subdivision: these are used to determine bounds on the number of steps required for differencing. It is shown that any curve whose rasterization fits in a space of $\omega$ pixels requires no more than $9\omega$ steps.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", keywords = "algorithms; reliability", subject = "{\bf I.3.3}: Computing Methodologies, COMPUTER GRAPHICS, Picture/Image Generation, Display algorithms. {\bf I.3.5}: Computing Methodologies, COMPUTER GRAPHICS, Computational Geometry and Object Modeling, Splines. {\bf G.1.2}: Mathematics of Computing, NUMERICAL ANALYSIS, Approximation, Spline and piecewise polynomial approximation.", } @Article{Hart:1994:VQR, author = "John C.

Unfortunately, quaternion rotation is often left as an advanced topic in computer graphics education due to difficulties in portraying the four-dimensional space of the quaternions. One tool for overcoming these obstacles is the quaternion demonstrator, a physical visual aid consisting primarily of a belt. Every quaternion used to specify a rotation can be represented by fixing one end of the belt and rotating the other. Multiplication of quaternions is demonstrated by the composition of rotations, and the resulting twists in the belt depict visually how quaternions interpolate rotation.\par This article introduces to computer graphics the exponential notation that mathematicians have used to represent unit quaternions. Exponential notation combines the angle and axis of the rotation into concise quaternion expression. This notation allows the article to present more clearly a mechanical quaternion demonstrator consisting of a ribbon and a tag, and develop a computer simulation suitable for interactive educational packages.

Its configuration can be altered by varying the joint angles. Although it is straight forward to compute figure configurations given joint angles (forward kinematics), it is more difficult to find the joint angles for a desired configuration (inverse kinematics). Since the inverse kinematics problem is of special importance to an animator wishing to set a figure to a posture satisfying a set of positioning constraints, researchers have proposed several different approaches. However, when we try to follow these approaches in an interactive animation system where the object on which to operate is as highly articulated as a realistic human figure, they fail in either generality or performance. So, we approach this problem through nonlinear programming techniques. It has been successfully used since 1988 in the spatial constraint system within {\em Jack}, a human figure simulation system developed at the University of Pennsylvania, and proves to be satisfactorily efficient, controllable, and robust. A spatial constraint in our system involves two parts: one constraint on the figure, the {\em end-effector}, and one on the spatial environment, the {\em goal}. These two parts are dealt with separately, so that we can achieve a neat modular implementation. Constraints can be added one at a time with appropriate weights designating the importance of this constraint relative to the others and are always solved as a group. If physical limits prevent satisfaction of all the constraints, the system stops with the (possibly local) optimal solution for the given weights. Also, the rigidity of each joint angle can be controlled, which is useful for redundant degrees of freedom.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", keywords = "algorithms; performance", subject = "{\bf I.3.7}: Computing Methodologies, COMPUTER GRAPHICS, Three-Dimensional Graphics and Realism, Animation. {\bf I.3.8}: Computing Methodologies, COMPUTER GRAPHICS, Applications.", } @Article{VanGelder:1994:TCI, author = "Allen {Van Gelder} and Jane Wilhelms", title = "Topological Considerations in Isosurface Generation", journal = j-TOG, volume = "13", number = "4", pages = "337--375", month = oct, year = "1994", CODEN = "ATGRDF", ISSN = "0730-0301 (print), 1557-7368 (electronic)", ISSN-L = "0730-0301", bibdate = "Sat Jan 13 12:49:28 1996", bibsource = "http://www.acm.org/pubs/contents/journals/tog/; http://www.math.utah.edu/pub/tex/bib/tog.bib", note = "See corrigendum: \cite{VanGelder:1995:CTC}.", URL = "http://www.acm.org/pubs/toc/Abstracts/0730-0301/195828.html", abstract = "A popular technique for rendition of isosurfaces in sampled data is to consider cells with sample points as corners and approximate the isosurface in each cell by one or more polygons whose vertices are obtained by interpolation of the sample data.

The two sample points have values on opposite sides of the threshold, and the interpolated point is called an {\em intersection point}.\par When one cell face has an intersection point in each of its four edges, then the correct connection among intersection points becomes ambiguous. An incorrect connection can lead to erroneous topology in the rendered surface, and possible discontinuities.

This paper studies the problems of disambiguation, reports on some solutions, and presents some statistics on the occurrence of such ambiguities.\par A natural way to incorporate neighborhood information is through the use of calculated gradients at cell corners. They provide insight into the behavior of a function in well-understood ways.

Point-feature label placement (PFLP) is the problem of placing text labels adjacent to point features on a map or diagram so as to maximize legibility. This problem occurs frequently in the production of many types of informational graphics, though it arises most often in automated cartography. In this paper we present a comprehensive treatment of the PFLP problem, viewed as a type of combinatorial optimization problem. Complexity analysis reveals that the basic PFLP problem and most interesting variants of it are NP-hard. These negative results help inform a survey of previously reported algorithms for PFLP; not surprisingly, all such algorithms either have exponential time complexity or are incomplete. To solve the PFLP problem in practice, then, we must rely on good heuristic methods. We propose two new methods, one based on a discrete form of gradient descent, the other on simulated annealing, and report on a series of empirical tests comparing these and the other known algorithms for the problem.

Its main goals are to show the expressive power of the language as well as its usefulness for geometric design. The language, named PLASM (the Programming LAnguage for Solid Modeling), introduces a very high level approach to ``constructive'' or ``generative'' modeling. Geometrical objects are generated by evaluating some suitable language expressions. Because generating expressions can be easily combined, the language also extends the standard variational geometry approach by supporting classes of geometric objects with varying topology and shape. The design language PLASM can be roughly considered as a geometry-oriented extension of a subset of the functional language FL. The language takes a dimension-independent approach to geometry representation and algorithms. In particular it implements an algebraic calculus over embedded polyhedra of any dimension. The generated objects are always geometrically consistent because the validity of geometry is guaranteed at a syntactical level. Such an approach allows one to use a representation scheme which is weaker than those usually adopted in solid modelers, thus encompassing a broader geometric domain, which contains solids, surfaces, and wire-frames, as well as higher-dimensional objects.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", keywords = "design; languages; theory", subject = "{\bf I.3.5}: Computing Methodologies, COMPUTER GRAPHICS, Computational Geometry and Object Modeling, Geometric algorithms, languages, and systems. {\bf D.1.1}: Software, PROGRAMMING TECHNIQUES, Applicative (Functional) Programming. {\bf D.3.2}: Software, PROGRAMMING LANGUAGES, Language Classifications, Applicative languages. {\bf D.3.2}: Software, PROGRAMMING LANGUAGES, Language Classifications, Design languages. {\bf I.3.5}: Computing Methodologies, COMPUTER GRAPHICS, Computational Geometry and Object Modeling, Curve, surface, solid, and object representations. {\bf I.3.5}: Computing Methodologies, COMPUTER GRAPHICS, Computational Geometry and Object Modeling, Hierarchy and geometric transformations. {\bf I.3.5}: Computing Methodologies, COMPUTER GRAPHICS, Computational Geometry and Object Modeling, Object hierarchies. {\bf J.6}: Computer Applications, COMPUTER-AIDED ENGINEERING, Computer-aided design (CAD).", } @Article{VanGelder:1995:CTC, author = "Allen {Van Gelder} and Jane Wilhelms", title = "Corrigendum: ``{Topological Considerations in Isosurface Generation}''", journal = j-TOG, volume = "14", number = "3", pages = "307--308", month = jul, year = "1995", CODEN = "ATGRDF", ISSN = "0730-0301 (print), 1557-7368 (electronic)", ISSN-L = "0730-0301", bibdate = "Sat Jan 13 12:33:38 1996", bibsource = "http://www.acm.org/pubs/contents/journals/tog/; http://www.math.utah.edu/pub/tex/bib/tog.bib", note = "See \cite{VanGelder:1994:TCI}.", URL = "http://www.acm.org/pubs/toc/Abstracts/0730-0301/215264.html", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", keywords = "algorithms; experimentation; performance; theory; verification", subject = "{\bf I.3.3}: Computing Methodologies, COMPUTER GRAPHICS, Picture/Image Generation, Display algorithms. {\bf I.3.5}: Computing Methodologies, COMPUTER GRAPHICS, Computational Geometry and Object Modeling, Boundary representations. {\bf I.3.5}: Computing Methodologies, COMPUTER GRAPHICS, Computational Geometry and Object Modeling, Curve, surface, solid, and object representations. {\bf I.3.5}: Computing Methodologies, COMPUTER GRAPHICS, Computational Geometry and Object Modeling, Geometric algorithms, languages, and systems.", } @Article{Glassner:1995:E, author = "Andrew S.

The approximations are hierarchies of spheres, and they allow the time-critical algorithm to progressively refine the accuracy of its detection, stopping as needed to maintain the real-time performance essential for interactive applications. The key to this approach is a preprocess that automatically builds tightly fitting hierarchies for rigid and articulated objects. The preprocess uses {\em medial-axis surfaces}, which are skeletal representations of objects. These skeletons guide an optimization technique that gives the hierarchies accuracy properties appropriate for collision detection. In a sample application, hierarchies build this way allow the time-critical collision-detection algorithm to have acceptable accuracy, improving significantly on that possible with hierarchies built by previous techniques. The performance of the time-critical algorithm in this application is consistently 10 to 100 times better than a previous collision-detection algorithm, maintaining low latency and a nearly constant frame rate of 10 frames per second on a conventional graphics workstation.

This uniform net is projected onto a number of other color spaces (CIE XYZ, tristimulus RGB, predistorted RGB, and YCC color space) to demonstrate and study the structure of color differences in these spaces on the basis of CIELAB color difference formulas. Two formulas are considered: the CIE 1976 formula *** and the newer CiE 1994 formula ***. The various color spaces considered are uniformly quantized and the grid of quantized points is transformed into CIELAB coordinates to study the distribution of color differences due to basic quantization steps and to specify the areas of the colors with the highest sensitivity to color discrimination. From a threshold value for the maximum color difference among neighboring quantized points searched for in each color space, concepts for the quantization of the color spaces are derived.

The new form is the symmetric analogue of the power form, because it can be regarded as an ``Hermite two-point expansion'' instead of a Taylor expansion. This form enjoys good numerical properties and admits a Horner-like evaluation algorithm that is almost as fast as that of the power form.

Because the prevalent representation of 3-D models for graphics purposes is polyhedral and because polyhedral models are in general triangulated for rendering, this article introduces a new compressed representation for complex triangulated models and simple, yet efficient, compression and decompression algorithms. In this scheme, vertex positions are quantized within the desired accuracy, a vertex spanning tree is used to predict the position of each vertex from 2,3, or 4 of its ancestors in the tree, and the correction vectors are entropy encoded. Properties, such as normals, colors, and texture coordinates, are compressed in a similar manner. The connectivity is encoded with no loss of information to an average of less than two bits per triangle. The vertex spanning tree and a small set of jump edges are used to split the model into a simple polygon. A triangle spanning tree and a sequence of marching bits are used to encode the triangulation of the polygon.

Humans view and understand high contrast scenes easily, ``adapting'' their visual response to avoid compression or truncation with no apparent loss of detail. By imitating some of these visual adaptation processes, we developed methods for the improved display of high-contrast images. The first builds a display image from several layers of lighting and surface properties. Only the lighting layers are compressed, drastically reducing contrast while preserving much of the image detail. This method is practical only for synthetic images where the layers can be retained from the rendering process. The second method interactively adjusts the displayed image to preserve local contrasts in a small ``foveal'' neighborhood. Unlike the first method, this technique is usable on any image and includes a new tone reproduction operator. Both methods use a sigmoid function for contrast compression.

While experience has shown that bounding boxes improve the performance of these algorithms in practice, the previous theoretical analysis has concluded that bounding boxes perform poorly in the worst case. This paper reconciles this discrepancy by analyzing intersections among $n$ geometric objects in terms of two parameters: $\alpha$, an upper bound on the {\em aspect ratio\/} or elongatedness of each object; and $\sigma$, an upper bound on the {\em scale factor\/} or size disparity between the largest and smallest objects. Letting $K_o$ and $K_b$ be the number of intersecting object pairs and bounding box pairs, respectively, we analyze a ratio measure of the bounding boxes' efficiency, $\rho = K_b/(n+K_o)$. The analysis proves that $\rho = O(\alpha \sqrt{\sigma}\log^2\sigma)$ and $\rho = \Omega(\alpha\sqrt(\sigma))$.\par One important consequence is that if and are small constants (as is often the case in practice), then $K_b = O(K_o) + O(n)$, so an algorithm that uses bounding boxes has time complexity proportional to the number of actual object intersections. This theoretical result validates the efficiency that bounding boxes have demonstrated in practice. Another consequence of our analysis is a proof of the output-sensitivity of an algorithm for reporting all intersecting pairs in a set of $n$ convex polyhedra with constant $\alpha$ and $\sigma$. The algorithm takes time $O(n log^(d-1)n + K_o log^(d-1)n)$ for dimension $d = 2, 3$.

The technique is a mixture of stochastic (density estimation) and deterministic (adaptive mesh refinement) algorithms used in a sequence and optimized to reduce the differences between the intermediate and final images as perceived by the human observer in the course of lighting computation. The quantitative measurements of visibility were obtained using the model of human vision captured in the visible differences predictor (VDP) developed by Daly [1993]. The VDP responses were used to support the selection of the best component algorithms from a pool of global illumination solutions, and to enhance the selected algorithms for even better progressive refinement of image quality. The VDP was also used to determine the optimal sequential order of component-algorithm execution, and to choose the points at which switchover between algorithms should take place. As the VDP is computationally expensive, it was applied exclusively at the design and tuning stage of the composite technique, and so perceptual considerations are embedded into the resulting solution, though no VDP calculations were performed during lighting simulation.\par The proposed illumination technique is also novel, providing intermediate image solutions of high quality at unprecedented speeds, even for complex scenes. One advantage of the technique is that local estimates of global illumination are readily available at the early stages of computing, making possible the development of a more robust adaptive mesh subdivision, which is guided by local contrast information.

We show that this basic approach can be extended to obtain better control over the morph, resulting in valid morphs with various natural properties. Two schemes, which generate the linear trajectory morph if it is valid, or a morph with trajectories close to linear otherwise, are presented. An efficient method for verification of validity of the linear trajectory morph between two triangulations is proposed. We also demonstrate how to obtain a morph with a natural evolution of triangle areas and how to find a smooth morph through a given intermediate triangulation.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", } @Article{Ouellette:2001:NSO, author = "Marc J.

Due to the nature of the integrand and of the domain of integration, these integrals seldom can be computed analytically. As a result, numerical techniques are used to find approximate solutions to these problems. While the numerical analysis literature offers many integration techniques, the choice of which method to use for specific computer graphic problems is a difficult one. This choice must be driven by the numerical efficiency of the method, and ultimately, by its visual impact on the computed image. In this paper, we begin to address these issues by methodically analyzing deterministic and stochastic numerical techniques and their application to the type of one-dimensional problems that occur in computer graphics, especially in the context of linear light source integration. In addition to traditional methods such as Gauss--Legendre quadratures, we also examine Voronoi diagram-based sampling, jittered quadratures, random offset quadratures, weighted Monte Carlo, and a newly introduced method of compounding known as a difficulty driven compound quadrature. We compare the effectiveness of these methods using a three-pronged approach. First, we compare the frequency domain characteristics of all the methods using periodograms. Next, applying ideas found in the numerical analysis literature, we examine the numerical and visual performance profiles of these methods for seven different one-parameter problem families. We then present results from the application of the methods for the example of linear light sources. Finally, we summarize the relative effectiveness of the methods surveyed, showing the potential power of difficulty-driven compound quadratures.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", } @Article{Ashikhmin:2002:SIT, author = "Michael Ashikhmin and Peter Shirley", title = "Steerable illumination textures", journal = j-TOG, volume = "21", number = "1", pages = "1--19", month = jan, year = "2002", CODEN = "ATGRDF", DOI = "http://doi.acm.org/10.1145/504789.504790", ISSN = "0730-0301 (print), 1557-7368 (electronic)", ISSN-L = "0730-0301", bibdate = "Thu Apr 11 17:55:04 MDT 2002", bibsource = "http://www.acm.org/pubs/contents/journals/tog/; http://www.math.utah.edu/pub/tex/bib/tog.bib", abstract = "We introduce a new set of illumination basis functions designed for lighting bumpy surfaces.

The framework provides a conceptual and mathematical foundation for analyzing known warps and for developing new warps, and serves as a common base for many warps and deformations. Our framework is composed of two components: a generic modular algorithm for warps and deformations; and a concise, geometrically meaningful formula that describes how warps are evaluated. Together, these two elements comprise a complete framework useful for analyzing, evaluating, designing, and implementing deformation algorithms. While the framework is independent of user-interfaces and geometric model representations and is formally capable of describing any warping algorithm, its design is geared toward the most prevalent class of user-controlled deformations: those computed using geometric operations. To demonstrate the expressive power of the framework, we cast several well-known warps in terms of the framework. To illustrate the framework's usefulness for analyzing and modifying existing warps, we present variations of these warps that provide additional functionality or improved behavior. To show the utility of the framework for developing new warps, we design a novel 3-D warping algorithm: a mesh warp---useful as a modeling and animation tool---that allows users to deform a detailed surface by manipulating a low-resolution mesh of similar shape. Finally, to demonstrate the mathematical utility of the framework, we use the framework to develop guarantees of several mathematical properties such as commutativity and continuity for large classes of deformations.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", keywords = "deformation; warp", } @Article{Goldman:2002:AGF, author = "Ron Goldman", title = "On the algebraic and geometric foundations of computer graphics", journal = j-TOG, volume = "21", number = "1", pages = "52--86", month = jan, year = "2002", CODEN = "ATGRDF", DOI = "http://doi.acm.org/10.1145/504789.504792", ISSN = "0730-0301 (print), 1557-7368 (electronic)", ISSN-L = "0730-0301", bibdate = "Thu Apr 11 17:55:04 MDT 2002", bibsource = "http://www.acm.org/pubs/contents/journals/tog/; http://www.math.utah.edu/pub/tex/bib/tog.bib", abstract = "Today's computer graphics is ostensibly based upon insights from projective geometry and computations on homogeneous coordinates.

Hints describe constraints on sizes and shapes inside characters and across the font that should be preserved during rasterization. We describe a novel, fast and fully automatic method for adding those hints to characters. The method is based on identifying hinting situations inside characters. It includes gathering global font information and linking it to characters, defining a set of constraints, sorting them, and converting them to hints in any known hinting technology (PostScript, TrueType or other). Our scheme is general enough to be applied on any language and on complex scripts such as Chinese Japanese and Korean. Although still inferior to expert manual hinting, our method produces high quality bitmaps which approach this goal.

Yet, to date, no one has invented a good way to easily and automatically adapt such designs to arbitrarily-sized electronic displays. The difficulty of generalizing grid-based designs explains the generally inferior nature of on-screen layouts when compared to their printed counterparts, and is arguably one of the greatest remaining impediments to creating on-line reading experiences that rival those of ink on paper. In this work, we present a new approach to adaptive grid-based document layout, which attempts to bridge this gap. In our approach, an adaptive layout style is encoded as a set of grid-based templates that know how to adapt to a range of page sizes and other viewing conditions. These templates include various types of layout elements (such as text, figures, etc.) and define, through constraint-based relationships, just how these elements are to be laid out together as a function of both the properties of the content itself, such as a figure's size and aspect ratio, and the properties of the viewing conditions under which the content is being displayed. We describe an XML-based representation for our templates and content, which maintains a clean separation between the two. We also describe the various parts of our research prototype system: a layout engine for formatting the page; a paginator for determining a globally optimal allocation of content amongst the pages, as well as an optimal pairing of templates with content; and a graphical user interface for interactively creating adaptive templates. We also provide numerous examples demonstrating the capabilities of this prototype, including this paper, itself, which has been laid out with our system.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", } @Article{DeCarlo:2003:SCC, author = "Doug DeCarlo and Adam Finkelstein and Szymon Rusinkiewicz and Anthony Santella", title = "Suggestive contours for conveying shape", journal = j-TOG, volume = "22", number = "3", pages = "848--855", month = jul, year = "2003", CODEN = "ATGRDF", ISSN = "0730-0301 (print), 1557-7368 (electronic)", ISSN-L = "0730-0301", bibdate = "Sat Oct 25 10:10:37 MDT 2003", bibsource = "http://www.acm.org/pubs/contents/journals/tog/; http://www.math.utah.edu/pub/tex/bib/tog.bib", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Graphics", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J778", } @Article{Kalnins:2003:CSS, author = "Robert D.
