Using a Simplification Mesh

Although simplifying a mesh directly as you did here is feasible in a few situations, in most cases you have to store entirely too many meshes for it to be useful in a real-world situation with many levels of detail. (Each level of detail requires a separate mesh.) What you need is a way to do something similar but without the requirement of all these mesh copies.

You can use the SimplificationMesh object to encapsulate the process of simplifying a mesh. However, you can't actually use the object to do the rendering; you must first get an actual mesh from the simplification mesh. Creating the simplification mesh is simple; here is the overload:

public SimplificationMesh ( Microsoft.DirectX.Direct3D.Mesh mesh , Microsoft.DirectX.GraphicsStream ...
