Parameters

flags
Type: Microsoft.WindowsMobile.DirectX.Direct3D.MeshFlags
Type of operation to perform as specified by one or more of the MeshFlags optimization methods.

adjacencyIn
Type: array<System.Int32[]
An array of three values per face that specify the three neighbors for each face in the source mesh. If the edge has no adjacent faces, the value is 0.

adjacencyOut
Type: array<System.Int32[]%
Array for the face adjacency array of the optimized mesh. The face adjacency is stored as an array of arrays. The innermost array is three indices of adjacent triangles, and the outermost array is one set of face adjacencies per triangle in the mesh.

faceRemap
Type: array<System.Int32[]%
Destination buffer that contains the new index for each face.

vertexRemap
Type: Microsoft.WindowsMobile.DirectX.GraphicsStream%
A GraphicsStream that contains the new index for each vertex.

Exceptions

Exception	Condition
InvalidCallException	The method call is invalid. For example, a method's parameter may contain an invalid value.
OutOfMemoryException	Direct3D could not allocate sufficient memory to complete the call.

Remarks

This method fails if the mesh is sharing its vertex buffer with another mesh, unless the OptimizeIgnoreVerts flag is set in the MeshFlags parameter.
