| Abstract |
|
Rendering specular highlights typically requires interpolation and
renormalization of a unit surface normal vector at each pixel of a
three-dimensional graphics image. This report discusses a technique for
modeling specular highlights using Bézier triangles. This approach
avoids computation by identifying those polygons for which it is not
necessary to calculate a specular highlight. The use of Bézier
triangles to model specular highlights suggests a general technique for
modeling, clipping and interpolation of shading functions.
