... objects and texture patterns. Reducing Object-Intersection Calculations Raysurface intersection calculations can account for as much as 95 percent of the processing time in a ray tracer. ... vectors in the viewing and specular-reflection direc- tions, we can calculate the value of cos4 with the dot product V R. Assuming the specular-reflection coefficient is a constant, we can .....
