WebJul 11, 2024 · That is, if the ray is parallel to the plane (in which case there is no intersection), so you want to check for that. With that, we can write the rest of the code: if direction.y == 0: return var distance = -origin.y/direction.y var position = origin + direction * distance And that position should be intersection with the y = 0 plane. WebNov 7, 2024 · 1. Represent the plane by the equation a x + b y + c z + d = 0 and plug the coordinates of the end points of the line segment into the left-hand side. If the resulting values have opposite signs, then the segment intersects the plane. If you get zero for either endpoint, then that point of course lies on the plane.
