- Note
- First we find the vertex candidates for the intersection region as follows: Add triangle vertices that are inside the tetrahedron Add tetrahedron vertices that are inside the triangle Add all intersection points of tetrahedron edges (codim 2) with the triangle (codim 0) (6*1 tests) Add all intersection points of triangle edges (codim 1) with tetrahedron faces (codim 1) (3*4 tests) Remove duplicate points from the list Compute the convex hull polygon Return a triangulation of that polygon as intersection
- Parameters
-
geo1/geo2 | The geometries to intersect |
intersection | Container to store the corner points of the polygon (as convex hull) |
- Note
- This overload is used when polygon like intersections are seeked
