WebTake the vector and do a dot product with the normal of the plane. If the result is 0, the plane and the ray are parallel. If the result is negative, the ray points towards the plane. If it is … 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 ).
