Detailed Description

template<class MeshT>
class OpenMesh::Decimater::ModRoundnessT< MeshT >

Use Roundness of triangles to control decimation.

In binary and mode, the collapse is legal if:

  • The roundness after the collapse is greater than the given value

In continuous mode the roundness after the collapse is returned

Member Function Documentation

template<class MeshT >
float OpenMesh::Decimater::ModRoundnessT< MeshT >::collapse_priority ( const CollapseInfo _ci)
inlinevirtual

Compute collapse priority due to roundness of triangle.

The roundness is computed by dividing the radius of the circumference by the length of the shortest edge. The result is normalized.

Returns
[0:1] or ILLEGAL_COLLAPSE in non-binary mode
LEGAL_COLLAPSE or ILLEGAL_COLLAPSE in binary mode

set_min_roundness()

Reimplemented from OpenMesh::Decimater::ModBaseT< MeshT >.

template<class MeshT >
void OpenMesh::Decimater::ModRoundnessT< MeshT >::set_min_roundness ( value_type  _min_roundness,
bool  _binary = true 
)
inline

Set a minimum roundness value.

Parameters
_min_roundnessin range (0,1)
_binarySet true, if the binary mode should be enabled, else false. In latter case the collapse_priority() returns a float value if the constraint does not apply and ILLEGAL_COLLAPSE else.
