abstract = "Ray tracing and other techniques employ algorithms
which require the intersection between a 3D parametric
ray and an object to be computed. The object to
intersect is typically a sphere, triangle, or polygon
but many surface types are possible. In this work we
consider intersections between rays and the simplest
parametric surface, the bilinear patch. Unlike other
surfaces, solving the ray-bilinear patch intersection
with simple algebraic manipulations fails. We present a
complete, efficient, robust, and graceful formulation
to solve ray-bilinear patch intersections quickly.
