WebThe point is behind the ray's origin when t is negative. When t is exactly 0, the point and the ray's origin are the same. The idea behind solving the ray-sphere intersection test is that … 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 ).
