Detailed Description

mitkQEMSimplification - an implementation for the simplification algorithm using Quadric Error Metrics (QEM)

mitkQEMSimplification is an implementation for the simplification algorithm using Quadric Error Metrics (QEM). The implementation is based on the algorithm presented in following papers written by Michael Garland and Paul S. Heckbert and their implementation in QSlim Simplification Software:

• Michael Garland and Paul S. Heckbert, Surface Simplification Using Quadric Error Metrics, in Proceedings of SIGGARPH'97, pp. 209-216, 1997.
• Michael Garland and Paul S. Heckbert, Simplifying Surfaces with Color and Texture using Quadric Error Metrics, in Proceedings of IEEE Visualization'98, pp. 263-269, 1998.

Thanks for their excellent works.
