## Detailed Description

Contains all the mesh ingredients like the polygonal mesh, the triangle mesh, different mesh kernels and mesh traits.

Martin, 26.12.2004: 1) replaced resize(size()-1) with pop_back(), since the later is more efficient 2) replaced interface_.set_heap_position(entry(0), -1); with reset_heap_position() 3) added const modifier to various functions TODO: in the moment the heap does not conform to the HeapInterface specification, i.e., copies are passed instead of references.

This is especially important for set_heap_position(), where the reference argument is non-const. The specification should be changed to reflect that the heap actually (only?) works when the heap entry is nothing more but a handle. TODO: change the specification of HeapInterface to make less(), greater() and get_heap_position() const. Needs changing DecimaterT. Might break someone's code.

## Function Documentation

## mesh_cast()

template<typename LHS , typename KERNEL >

LHS OpenMesh::mesh_cast | ( | PolyMeshT< KERNEL > & | rhs | ) |

Cast a mesh with different but identical traits into each other.

Example:

struct TriTraits1 : public OpenMesh::DefaultTraits {
typedef Vec3d Point;
};
struct TriTraits2 : public OpenMesh::DefaultTraits {
typedef Vec3d Point;
};
struct TriTraits3 : public OpenMesh::DefaultTraits {
typedef Vec3f Point;
};
TriMesh_ArrayKernelT<TriTraits1> a;
TriMesh_ArrayKernelT<TriTraits2> &b = mesh_cast<TriMesh_ArrayKernelT<TriTraits2>&>(a); // OK
TriMesh_ArrayKernelT<TriTraits3> &c = mesh_cast<TriMesh_ArrayKernelT<TriTraits3>&>(a); // ERROR
