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. Now the intersection between line and plane is found, so we need to verify if the given intersection lies inside the triangle: C#. Shrink .

WebGiven a pointer-based region octree, intersections of the ray with a node's bisecting planes are first evaluated to determine in which sub-octants the ray-node intersections may lie; a local ordering then determines the sequence in which these sub-octants should be examined so that the intersection closest to the ray's origin can be selected.
