WebIn this paper, we present a parallel architecture for ray tracing based on a uniform spatial subdivision of the scene and exploiting an embedded computation of ray-triangle intersections. Web2. Which normals to use for ray-triangle intersection? The scene file provides a normal for every triangle vertex. However, those normals should NOT be used for ray-triangle intersection. For the intersection calculation, you need to compute the normal of the plane containing the triangle. You do so by taking a cross product of two edges: chuchoter clipart

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 ).
