ID3DXMesh Interface

Applications use the methods of the ID3DXMesh interface to manipulate mesh objects.

ID3DXMesh Members

CloneMesh	Clones a mesh using a declarator.
CloneMeshFVF	Clones a mesh using a flexible vertex format (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.
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.
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.
LockAttributeBuffer	Locks the mesh buffer that contains the mesh attribute data, and returns a pointer to it.
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	Controls the reordering of mesh faces and vertices to optimize performance, generating an output mesh.
OptimizeInplace	Controls the reordering of mesh faces and vertices to optimize performance.
SetAttributeTable
UnlockAttributeBuffer	Unlocks an attribute buffer.
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 ID3DXMesh interface, call either the D3DXCreateMesh or D3DXCreateMeshFVF 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 LPD3DXMESH type is defined as a pointer to the ID3DXMesh interface.

typedef struct ID3DXMesh *LPD3DXMESH;
