WebIn 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images.. On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping and path tracing, … WebThe normal of the plane is also the normal of the triangle. We use the cross product (non-commutative) between A and B to calculate the normal. The equation for the ray is P = O + tR ( P: intersection with the triangle, O: COP (centre of projection), R: directional vector of the ray, t: Distance between O and P ).
