Controls the reordering of mesh faces and vertices to optimize performance and generate an output mesh.

Namespace: Microsoft.WindowsMobile.DirectX.Direct3D
Assembly: Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)

'Usage
Dim instance As Mesh

Parameters

flags
Type: Microsoft.WindowsMobile.DirectX.Direct3D.MeshFlags
Specifies type of operation to conform to using one or more of the following MeshFlags enumerations:
IbWriteOnly
Use32Bit

adjacencyIn
Type: Microsoft.WindowsMobile.DirectX.GraphicsStream
A GraphicsStream containing 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[]%
An 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.

Return Value

Type: Microsoft.WindowsMobile.DirectX.Direct3D.Mesh
A Mesh object that represents the optimized mesh.

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 is similar to the Clone method for a BaseMesh, except that it can perform optimization while generating the new clone of the mesh.

The output mesh inherits all of the creation parameters of the input mesh.
