Plane-Tetrahedron intersection: How to ensure points are on the edge or inside the tetrahedron, or on the edge or outside the tetrahedron?
Consider the case where the intersection is a quadrangle, and some of the points of intersection on the tetrahedron edges cannot be given exactly (given the numbers used to represent coordinates i.e. not real numbers, but a limited subset e.g.…

How to determine if a 3D line segment intersects a side of a 3D rectangular prism?
I am trying to find a way to determine if a line segment drawn between two points in 3D space will intersect another 3D body (rectangular prism) that is defined by regions using (x, y, z) vertices.
Is there a way to do this in Matlab?
