ID3DXSPMesh Interface

Applications use the methods of the ID3DXSPMesh interface to manipulate simplification mesh objects. A simplification mesh is used to simplify a given mesh to a lower number of faces.

ID3DXSPMesh Members

CloneMesh	Clones a mesh using a declarator.
CloneMeshFVF	Clones a mesh using a flexible vertex format (FVF) code.
ClonePMesh	Clones a progressive mesh using a declarator.
ClonePMeshFVF	Clones a progressive mesh using a FVF code.
GetDeclaration	Retrieves a declaration describing the vertices in the mesh.
GetDevice	Retrieves the device object associated with the simplification mesh.
GetFVF	Retrieves the FVF of the vertices in the simplification mesh.
GetMaxFaces	Retrieves the maximum number of faces that the simplification mesh supports.
GetMaxVertices	Retrieves the maximum number of vertices that the simplification mesh supports.
GetNumFaces	Retrieves the number of faces in the simplification mesh.
GetNumVertices	Retrieves the number of vertices in the simplification mesh.
GetOptions	Retrieves the mesh options enabled for this simplification mesh at creation time.
GetVertexAttributeWeights	Returns the per-vertex attribute weights used to create the ID3DXSPMesh object.
GetVertexWeights	Returns the per-vertex weights used to create the ID3DXSPMesh object.
ReduceFaces	Reduces the number of faces in a simplification mesh.
ReduceVertices	Reduces the number of vertices in a simplification mesh.

Remarks

The ID3DXSPMesh interface is obtained by calling the D3DXCreateSPMesh function.

The ID3DXSPMesh interface, like all Component Object Model (COM) interfaces, inherits the IUnknown interface.

The LPD3DXSPMESH type is defined as a pointer to the ID3DXSPMesh interface.

typedef struct ID3DXSPMesh *LPD3DXSPMESH;
