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 ). WebAug 14, 2016 · 1. The first thing to do is to find the intersection of the line with the plane of the triangle. The plane can be found by first computing the cross product of b − a and c − …
WebJul 29, 2007 · P and P3 are on the plane. N is the plane Normal vector. P = P1 + v (P2 - P1) (Eq2) So the intersection is given by: Eq1 = Eq2 or. N dot (P1 + v (P2 - P1)) = N dot P3. …
WebI would first calculate the 2 edges, p0p1 and p0p2, then I'll get the area of the whole triangle (area_p0p1p2).
