WebThe power of ray tracing lies in the fact that secondary rays are fired from the ray-object intersection point to determine its exact illumination (and hence colour). This spawning of secondary rays allows reflection, refraction, and shadowing to be handled with ease. Ray tracing's big disadvantage is that it is slow. WebMar 9, 2009 · 1.

"WebA polygon mesh is made of vertices connected to each other to form faces. The first thing we expect to define a mesh is a list of vertices. Let's consider an example of two quads sharing a common edge (figure 1). In this example, we would have 6 vertices v0, v1, v2, v3, v4, and v5. The other information we need is the mesh's total number of ... " - Ray tracing polygon intersection
