示例1: getFaceArea
void MeshDenoisingBase::getFaceArea(TriMesh &mesh, std::vector<double> &area)
{
area.resize(mesh.n_faces());
for(TriMesh::FaceIter f_it = mesh.faces_begin(); f_it != mesh.faces_end(); f_it++)
{
std::vector<TriMesh::Point> point;
point.resize(3); int index = 0;
for(TriMesh::FaceVertexIter fv_it = mesh.fv_iter(*f_it); fv_it.is_valid(); fv_it++)
{
point[index] = mesh.point(*fv_it);
index++;
}
TriMesh::Point edge1 = point[1] - point[0];
TriMesh::Point edge2 = point[1] - point[2];
double S = 0.5 * (edge1 % edge2).length();
area[(*f_it).idx()] = S;
}
}示例2: computeNormals
bool computeNormals(TriMesh mesh)
{
OpenMesh::FPropHandleT<TriMesh::Point> trueNormals;
OpenMesh::FPropHandleT<TriMesh::Point> approxNormals;
mesh.add_property(trueNormals);
mesh.add_property(approxNormals);

++valence;
}
mesh.property(approxNormals,f_it) /= valence;
}
return true;
} // bool computeNormals(TriMesh mesh)
