ID3DXPMesh Interface

Applications use the methods of the ID3DXPMesh interface to manipulate progressive mesh objects. A progressive mesh enables progressive refinement of the mesh object.

ID3DXPMesh 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.
ConvertAdjacencyToPointReps	Converts mesh adjacency information to an array of point representatives.
ConvertPointRepsToAdjacency	Converts point representative data to mesh adjacency information.
DrawSubset	Draws a subset of a mesh.
GenerateAdjacency	Generates adjacency information based on mesh indices.
GenerateVertexHistory	Generate an immediate ancestor for each vertex when it is removed by a vertex split. Allows generation of a geomorph.
GetAdjacency	Returns the face adjacency array of the mesh.
GetAttributeTable	Retrieves either an attribute table for a mesh, or the number of entries stored in an attribute table for a mesh.
GetDeclaration	Retrieves a declaration describing the vertices in the mesh.
GetDevice	Retrieves the device associated with the mesh.
GetFVF	Get the fixed function vertex value.
GetIndexBuffer	Retrieves the data in an index buffer.
GetMaxFaces	Retrieves the maximum number of faces that the progressive mesh supports.
GetMaxVertices	Retrieves the maximum number of vertices that the progressive mesh supports.
GetMinFaces	Retrieves the minimum number of faces that the progressive mesh supports.
GetMinVertices	Retrieves the minimum number of vertices that the progressive mesh supports.
GetNumBytesPerVertex	Gets the number of bytes per vertex.
GetNumFaces	Retrieves the number of faces in the mesh.
GetNumVertices	Retrieves the number of vertices in the mesh.
GetOptions	Retrieves the mesh options enabled for this mesh at creation time.
GetVertexBuffer	Retrieves the data in a vertex buffer.
LockIndexBuffer	Locks an index buffer and obtains a pointer to the index buffer memory.
LockVertexBuffer	Locks a vertex buffer and obtains a pointer to the vertex buffer memory.
Optimize	Generates an output mesh with reordered faces and vertices to optimize performance.
OptimizeBaseLOD	Optimizes the base level of detail (LOD) part of an ID3DXPMesh object.
Save	Saves the progressive mesh to the specified stream object.
SetNumFaces	Sets the current level of detail to as close to the specified number of faces as possible.
SetNumVertices	Sets the current level of detail to as close to the specified number of vertices as possible.
TrimByFaces	Modifies the minimum and maximum level of detail (LOD) of an ID3DXPMesh object.
TrimByVertices	Modifies the minimum and maximum level of detail (LOD) of an ID3DXPMesh object.
UnlockIndexBuffer	Unlocks an index buffer.
UnlockVertexBuffer	Unlocks a vertex buffer.
UpdateSemantics	This method allows the user to change the mesh declaration without changing the data layout of the vertex buffer. The call is valid only if the old and new declaration formats have the same vertex size.

Remarks

To obtain the ID3DXPMesh interface, call the D3DXGeneratePMesh function.

This interface inherits additional functionality from the ID3DXBaseMesh interface.

This interface, like all Component Object Model (COM) interfaces, inherits additional functionality from the IUnknown interface.

The LPD3DXPMESH type is defined as a pointer to the ID3DXPMesh interface, as shown below.

typedef struct ID3DXPMesh *LPD3DXPMESH;
