Simplification of Surface Data

​Quadric error metric introduced by Michael Garland and a modified ​qslim algorithm is used for simplification, in the context of surface data. This method is now implemented in ​MeshKit using ​MOAB.

Initial triangles are positively oriented in the plane, and an additional constraint is introduced as a penalty in the decimation algorithm, to avoid negatively oriented triangles. This ensures that the surface of the glacier still has a proper representation after decimation.

In this example, the surface is decimated to 20000 triangles.
