| TriMeshType & | res, | ||
| float | tol = 0 |
||
| ) |
Compute the intersection between a mesh and a ball. given a mesh return a new mesh made by a copy of all the faces entirely includeded in the ball plus new faces created by refining the ones intersected by the ball border. It works by recursively splitting the triangles that cross the border, as long as their area is greater than a given value tol. If no value is provided, 1/10^5*2*pi*radius is used NOTE: the returned mesh is a triangle soup

| Plane3< ScalarType > | pl, | ||
| EdgeMeshType & | em | ||
| ) |
More stable version of the IntersectionPlaneMesh function.
This version of the make a first pass storing the distance to the plane into a vertex attribute and then use this value to compute in a safe way the intersection.

| bool vcg::IntersectionPlaneMeshOld | ( | TriMeshType & | m, |
| Plane3< ScalarType > | pl, | ||
| EdgeMeshType & | em | ||
| ) |
Compute the intersection between a trimesh and a plane building an edge mesh.
Basic Function Computing the intersection between a trimesh and a plane. It returns an EdgeMesh without needing anything else. Note: This version always returns a segment for each triangle of the mesh which intersects with the plane. In other words there are 2*n vertices where n is the number of segments fo the mesh. You can run vcg::edge:Unify to unify the vertices closer that a given value epsilon. Note that, due to subtraction error during triangle plane intersection, it is not safe to put epsilon to 0.
