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)

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.

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

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

Set a minimum roundness value.

_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.
