## Detailed Description

### template<class MeshT>
class OpenMesh::Decimater::ModNormalDeviationT< MeshT >

Use Normal deviation to control decimation.

The module tracks the normals while decimating a normal cone consisting of all normals of the faces collapsed together is computed and if a collapse would increase the size of the cone to a value greater than the given value the collapse will be illegal.

In binary and mode, the collapse is legal if:

- The normal deviation after the collapse is lower than the given value

In continuous mode the maximal deviation is returned

## Member Function Documentation

template<class MeshT >

float OpenMesh::Decimater::ModNormalDeviationT< MeshT >::collapse_priority | ( | const CollapseInfo & | _ci | ) |
| inline

Control normals when Decimating.

Binary and Cont. mode.

The module tracks the normals while decimating a normal cone consisting of all normals of the faces collapsed together is computed and if a collapse would increase the size of the cone to a value greater than the given value the collapse will be illegal.

Parameters

  _ci | Collapse info data

Returns
  Half of the normal cones size (radius in radians)
