Ray of a triangle
WebOct 22, 2016 · The intersection point with the ray, if it exists, is given by solving n ⋅ (y(t) − (x1, y1, z1)) = 0 for t ≥ 0. Lastly, you have to check if the intersection point lies on the triangle. To do this let y be the intersection point and suppose it does not lie on a boundary of the triangle (if it does then you are done).
