示例1: remove_inside
/// Removes triangles from mesh that are inside p (helper function for Boolean operations on polyhedra)
void Polyhedron::remove_inside(IndexedTriArray& mesh, Polyhedron& p, bool remove_shared)
{
// get the vertices and facets
const vector<Vector3>& verts = mesh.get_vertices();
vector<IndexedTri> facets = mesh.get_facets();
// check whether each vertex is inside or outside the polyhedron
vector<LocationType> loc(verts.size());
for (unsigned i=0; i< loc.size(); i++)
loc[i] = p.location(verts[i]);
// now determine the facets that are inside the mesh (and shared)
for (unsigned i=0; i< facets.size(); i++)
{
// if we are removing shared, see whether all points are on the polyhedron
if (remove_shared)
{
if (loc[facets[i].a] == eOnVertex && loc[facets[i].b] == eOnVertex &&
loc[facets[i].c] == eOnVertex)
{
facets[i] = facets.back();
facets.pop_back();
i--;
continue;
}
}
// see whether a single point is inside
if (loc[facets[i].a] == eInside || loc[facets[i].b] == eInside ||
loc[facets[i].c] == eInside)
{
facets[i] = facets.back();
facets.pop_back();
i--;
continue;
}
}
// now reinstantiate the mesh
mesh = IndexedTriArray(verts.begin(), verts.end(), facets.begin(), facets.end());
