I implemented this, but the hit depth seems to be incorrect. I suspect this is because it assumes (erroneously) that the cross section …
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 ).
