Detailed Description

template<typename MeshT>
class OpenMesh::Decimater::ModNormalFlippingT< MeshT >

Decimating module to avoid flipping of faces.

This module can be used only as a binary module. The criterion of allowing/disallowing the collapse is the angular deviation between the face normal of the original faces and normals of the faces after the collapse. The collapse will pass the test, if the deviation is below a given threshold.

Member Function Documentation

collapse_priority()

template<typename MeshT >

float OpenMesh::Decimater::ModNormalFlippingT< MeshT >::collapse_priority ( const CollapseInfo &  _ci )

inlineoverride

Compute collapse priority due to angular deviation of face normals before and after a collapse.

1. Compute for each adjacent face of _ci.v0 the face normal if the collpase would be executed.
2. Prevent the collapse, if the cosine of the angle between the original and the new normal is below a given threshold.

Parameters

_ci	The collapse description

Returns

LEGAL_COLLAPSE or ILLEGAL_COLLAPSE
