Detailed Description

template<typename MeshType, typename RealType = double>
class OpenMesh::Subdivider::Uniform::MidpointT< MeshType, RealType >

Midpoint subdivision algorithm.

With every step, the set of vertices is replaced by the midpoints of all current edges. Then, two sets of faces are created to set up the new connectivity: From all midpoints of edges surrounding an original face, a new face is created. Also, for all midpoints of edges surrounding an original vertex, a new face is created.

Note

This algorithm ignores the _update_points option.

This algorithm is best suited for closed meshes since boundaries tend to fragment into isolated faces after a few iterations.

Member Function Documentation

cleanup()

template<typename MeshType , typename RealType = double>

bool OpenMesh::Subdivider::Uniform::MidpointT< MeshType, RealType >::cleanup ( mesh_t &  _m )

inlineprotectedvirtual

Cleanup mesh after usage, e.g. remove added properties.

Implements OpenMesh::Subdivider::Uniform::SubdividerT< MeshType, RealType >.

name()

template<typename MeshType , typename RealType = double>

const char * OpenMesh::Subdivider::Uniform::MidpointT< MeshType, RealType >::name ( ) const

inlinevirtual

Return name of subdivision algorithm.

Implements OpenMesh::Subdivider::Uniform::SubdividerT< MeshType, RealType >.

prepare()

template<typename MeshType , typename RealType = double>

bool OpenMesh::Subdivider::Uniform::MidpointT< MeshType, RealType >::prepare ( mesh_t &  )

inlineprotectedvirtual

Prepare mesh, e.g.

add properties

You have to reimplement this function to setup your mesh. The default implementation will always return false and therefore block your algorithm.

Reimplemented from OpenMesh::Subdivider::Uniform::SubdividerT< MeshType, RealType >.

subdivide()

template<typename MeshType , typename RealType = double>

bool OpenMesh::Subdivider::Uniform::MidpointT< MeshType, RealType >::subdivide ( mesh_t &  _m, size_t  _n, const bool  _update_points = true  )

inlineprotectedvirtual

Performs one step of Midpoint subdivision.

Note

The _update_points option is ignored

Implements OpenMesh::Subdivider::Uniform::SubdividerT< MeshType, RealType >.
