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.
| Method | Description |
|---|---|
| ID3DXSPMesh::CloneMesh | Clones a mesh using a declarator. |
| ID3DXSPMesh::CloneMeshFVF | Clones a mesh using a flexible vertex format (FVF) code. |
| ID3DXSPMesh::ClonePMesh | Clones a progressive mesh using a declarator. |
| ID3DXSPMesh::ClonePMeshFVF | Clones a progressive mesh using a flexible vertex format (FVF) code. |
| ID3DXSPMesh::GetDeclaration | Retrieves a declaration describing the vertices in the mesh. |
| ID3DXSPMesh::GetDevice | Retrieves the device object associated with the simplification mesh. |
| ID3DXSPMesh::GetFVF | Retrieves the flexible vertex format (FVF) of the vertices in the simplification mesh. |
| ID3DXSPMesh::GetMaxFaces | Retrieves the maximum number of faces that the simplification mesh supports. |
| ID3DXSPMesh::GetMaxVertices | Retrieves the maximum number of vertices that the simplification mesh supports. |
| ID3DXSPMesh::GetNumFaces | Retrieves the number of faces in the simplification mesh. |
| ID3DXSPMesh::GetNumVertices | Retrieves the number of vertices in the simplification mesh. |
| ID3DXSPMesh::GetOptions | Retrieves the mesh options enabled for this simplification mesh at creation time. |
| ID3DXSPMesh::GetVertexAttributeWeights | Retrieves the per-vertex attribute weights used to create the ID3DXSPMesh object. |
| ID3DXSPMesh::GetVertexWeights | Retrieves the per-vertex weights used to create the ID3DXSPMesh object. |
| ID3DXSPMesh::ReduceFaces | Reduces the number of faces in a simplification mesh. |
| ID3DXSPMesh::ReduceVertices | Reduces the number of vertices in a simplification mesh. |
The ID3DXSPMesh interface is obtained by calling the D3DXCreateSPMesh function.
The LPD3DXSPMESH> type is defined as a pointer to the ID3DXSPMesh interface.
