## 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.

Get an internal name for a type Important, this is depends on compilers and versions, do NOT use in file formats! This provides property type safety when only limited RTTI is available Solution adapted from OpenVolumeMesh.

This file contains all code required to use Eigen3 vectors as Mesh vectors.

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

## create_property_from_string()

template<typename HandleT >

void OpenMesh::create_property_from_string | ( | BaseKernel & | _mesh,
|  | const std::string & | _type_name,
|  | const std::string & | _property_name
| ) |  |

Create a property with type corresponding to _type_name on _mesh with name _property_name.

For user defined types you need to register the type using OM_REGISTER_PROPERTY_TYPE(ClassName, TypeString)

## 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
OpenMesh::Vec3f
VectorT< float, 3 > Vec3f
3-float vector
