WebSlide 20 of 23 WebThere are other ways to compute views of scenes defined by geometric primitives. One of the most common is ray-casting. Ray-casting searches along lines of sight, or rays, to determine the primitive that is visible along it.

WebTo intersect a ray with a face, the ray is intersected with the planar equation of the face and then the point of intersection is tested to see if it is inside the polygonal face. Care must be taken in correctly counting intersections if this semi-infinite ray intersects the object exactly at an edge or vertex or if the ray is colinear with an edge of the object. critter cabana near meWebMost rays will intersect only a few primitives and miss the others by a large distance.
