Detailed Description

template<typename MeshType, typename RealType = float>
class OpenMesh::Subdivider::Uniform::CompositeT< MeshType, RealType >

This class provides the composite subdivision rules for the uniform case.

To create a subdivider derive from this class and overload the functions name() and apply_rules(). In the latter one call the wanted rules.

For details on the composite scheme refer to

P. Oswald, P. Schroeder "Composite primal/dual sqrt(3)-subdivision schemes", CAGD 20, 3, 2003, 135–164

Note: Not all rules are implemented!

Member Function Documentation

◆ apply_rules()

template<typename MeshType , typename RealType = float>

virtual void OpenMesh::Subdivider::Uniform::CompositeT< MeshType, RealType >::apply_rules ( void )

protectedpure virtual

Assemble here the rule sequence, by calling the constructor of the wanted rules.

Implemented in OpenMesh::Subdivider::Uniform::CompositeLoopT< MeshType, RealType >, and OpenMesh::Subdivider::Uniform::CompositeSqrt3T< MeshType, RealType >.

◆ cleanup()

template<typename MeshType , typename RealType = float>

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

inlineoverrideprotectedvirtual

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

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

◆ name()

template<typename MeshType , typename RealType = float>

virtual const char * OpenMesh::Subdivider::Uniform::CompositeT< MeshType, RealType >::name ( void ) const

overridepure virtual

Return name of subdivision algorithm.

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

Implemented in OpenMesh::Subdivider::Uniform::CompositeLoopT< MeshType, RealType >, and OpenMesh::Subdivider::Uniform::CompositeSqrt3T< MeshType, RealType >.

◆ prepare()

template<typename MeshType , typename RealType >

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

overrideprotectedvirtual

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 = float>

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

inlineoverrideprotectedvirtual

Subdivide mesh _m _n times.

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