Since you’re got a line segment, you’ll also have to test that the line segment actually intersects the triangle’s plane in the first place (and in the case that it’s in the plane, intersects the triangle). – amd Jun 24, 2024 at 23:54 Show 1 more comment Nettet28. sep. 2024 · The points inside the triangle can be described as the (convex) vector sum A + b AB + c AC where b ≥ 0, c ≥ 0, b + c ≤ 1. The points on the (half) ray are P + q PQ. under the condition q ≥ 0. So to find the intersection, you can solve the vector equation A + b AB + c AC = P + q PQ or b AB + c AC + q QP = AP, la suelita roja letra
