ID3DXBaseMesh Interface

Applications use the methods of the ID3DXBaseMesh interface to manipulate and query mesh and progressive mesh objects.

ID3DXBaseMesh 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.
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.
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

The ID3DXBaseMesh interface, like all COM interfaces, inherits the IUnknown interface methods.
A mesh is an object made up of a set of polygonal faces. A mesh defines a set of vertices and a set of faces (the faces are defined in terms of the vertices and normals of the mesh).
The LPD3DXBASEMESH type is defined as a pointer to the ID3DXBaseMesh interface.
typedef struct ID3DXBaseMesh *LPD3DXBASEMESH;
