WebMay 31, 2024 · Explanation: If one plane is identical to the other except translated by some vector not in the plane, then the two planes do not intersect – they are parallel. If the two planes coincide, then they intersect in a plane. If neither of the above cases hold, then the planes will intersect in a line. WebRay intersection in software • Scenes usually have many objects • Need to ﬁnd the ﬁrst intersection along the ray – that is, the one with the smallest positive t value • Loop over objects – ignore those that don’t intersect – keep track of the closest seen so far – Convenient to give rays an ending t value for this purpose (then

The point where the lines intersect is known as the point of intersection. Do two planes intersect in a ray? The intersection of two planes is a line. They cannot intersect at only one point because planes are infinite.

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.
