Detailed Description

Use Roundness of triangles to control decimation.

In binary and mode, the collapse is legal if:

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 )

inlineoverridevirtual

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

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_roundness	in range (0,1)
_binary	Set 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.
