## Detailed Description

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

Use aspect ratio to control decimation.

This module computes the aspect ratio.

In binary mode, the collapse is legal if:

- The aspect ratio after the collapse is greater
- The aspect ratio after the collapse is greater than the given minimum

In continuous mode the collapse is illegal if:

- The aspect ratio after the collapse is smaller than the given minimum
