  abstract =     "This paper presents a method to compute a view frustum
                 for a 3D object viewed from a given viewpoint, such
                 that the object is completely enclosed in the frustum
                 and the object's image area is also near-maximal in the
                 given 2D rectangular viewing region. This optimization
                 can be used to improve the resolution of shadow maps
                 and texture maps for projective texture mapping.
                 Instead of doing the optimization in 3D space to find a
                 good view frustum, our method uses a 2D approach. The
                 basic idea of our approach is as follows. First, from
                 the given viewpoint, a conveniently-computed view
                 frustum is used to project the 3D vertices of the
                 object to their corresponding 2D image points. A tight
                 2D bounding quadrilateral is then computed to enclose
                 these 2D image points. Next, considering the projective
                 warp between the bounding quadrilateral and the
                 rectangular viewing region, our method applies a
                 technique of camera calibration to compute a new view
                 frustum that generates an image that covers the viewing
                 region as much as possible.",
