int removeContact	(	const IndSimpSet< N, N-1, A, T, V, IS > &	surface,
		VertexForwardIterator	verticesBeginning,
		VertexForwardIterator	verticesEnd
	)			[related, inherited]

Move the vertices to remove contact.

Parameters:

	surface	The surface of an object.
	verticesBeginning	The beginning of a range of vertices.
	verticesEnd	The end of a range of vertices.

Returns:

The number of vertices moved.

For each vertex in the range: If the vertex is inside the object, move it to lie on the surface of the object (specifically, the closest point on the surface).

One can use this function to roughly remove contact between two solid meshes. Consider two tetrahedron meshes A and B. Extract the boundary of A and the boundary vertices of B. Then call this function with the triangle mesh and the boundary vertices. Update the position of the boundary vertices of B. Now the boundary vertices of B do not penetrate A. (B itself may stil intersect A, though.) Next repeat these steps with the roles of A and B reversed. Now the boundary vertices of A do not penetrate B.

Note that since we have change the boundary of A, it is possible that some boundary vertices of B now penetrate A. (It's not likely, but it's possible.) If it is necessary that this not happen, keep calling this function until no vertices are moved.
