Detailed Description

Surface mesh simplification based on approximation error and fairness criteria.

It performs incremental greedy mesh simplification based on halfedge collapses. See the following papers for more details:

• Michael Garland and Paul Seagrave Heckbert. Surface simplification using quadric error metrics. SIGGRAPH 1997.
• Leif Kobbelt et al. A general framework for mesh decimation. In Proceedings of Graphics Interface, 1998.
