Ray tracing nurbs surfaces using cuda
WebNothing stops us from using polygonal meshes or NURBS surfaces with our renderer, but computing the intersection of a ray with these primitives can be difficult and slow. On the other hand, computing the intersection of a ray with a triangle is a relatively simple operation that can also be well-optimized. WebRay tracing implicit surfaces using Sturm's theorem. I am trying to render implicit surfaces given by a polynomial equation F ( x, y, z) = 0 using Sturm's theorem. Plugging the parametric ray equation r ( t) = o + t d, where o ∈ R 3 is the ray origin and d ∈ R 3 ∖ { 0 } is the ray direction, into F yields a polynomial equation p ( t) = 0 ...
