A triangle mesh primitive for meshes on the surface that need to conform to terrain.

Initialize	Initializes a default surface mesh primitive. This is equivalent to constructing a surface mesh with a Set Hint of Frequent and a Surface Mesh Rendering Method of Automatic.
InitializeWithSetHint	Initializes a surface mesh primitive with the specified setHint. This is equivalent to constructing a surface mesh with the specified setHint and a Surface Mesh Rendering Method of Automatic.
InitializeWithSetHintAndRenderingMethod	Initializes a surface mesh primitive with the specified setHint and renderingMethod.
Supported	Determines whether or not the video card supports the surface mesh primitive with the given renderingMethod.
SupportedWithDefaultRenderingMethod	Determines whether or not the video card supports the surface mesh primitive. This is equivalent to calling Supported with Automatic.
