WebThis gives the line of intersection of uv-parameter triangle with the st-parameter plane. Similarly the line of intersection of st-triangle with the uv-plane is computed. Then the common segment if any is the line intersection between the two triangles, for details see [9,13]. This algorithm works only if the triangles cross intersect.

WebIn analytic geometry, the intersection of a line and a plane in three-dimensional space can be the empty set, a point, or a line. It is the entire line if that line is embedded in the plane, and is the empty set if the line is parallel to the plane but outside it. Otherwise, the line cuts through the plane at a single point.
