ID3DX10Mesh interface

Applications use the methods of the ID3DX10Mesh interface to manipulate mesh objects.

Members

The ID3DX10Mesh interface inherits from the IUnknown interface. ID3DX10Mesh also has these types of members:

• Methods

Methods

The ID3DX10Mesh interface has these methods.

Method	Description
CloneMesh	Creates a new mesh and fills it with the data of a previously loaded mesh.
CommitToDevice	Commit any changes made to a mesh to the device so that the changes can be rendered. This should be called after a mesh's data is altered and before it is rendered. A mesh cannot be rendered unless it is committed to the device. See remarks.
Discard	Removes mesh data from the device that has been committed to the device (with ID3DX10Mesh::CommitToDevice).
DrawSubset	Draws a subset of a mesh.
DrawSubsetInstanced	Draw several instances of the same subset of a mesh.
GenerateAdjacencyAndPointReps	Generate a list of mesh edges, as well as a list of faces that share each edge.
GenerateAttributeBufferFromTable	Generate an attribute buffer from the data in the mesh's attribute table. An attribute buffer is another format for storing the data in the attribute table. Both the attribute buffer and the attribute table are internal data structures in the mesh.
GenerateGSAdjacency	Adds adjacency data to the mesh's index buffer. When the mesh is to be sent to a geometry shader that takes adjacency data, it is neccessary for the mesh's index buffer to contain adjacency data.
GetAdjacencyBuffer	Access the mesh's adjacency buffer.
GetAttributeBuffer	Access the mesh's attribute buffer.
GetAttributeTable	Retrieves either an attribute table for a mesh, or the number of entries stored in an attribute table for a mesh.
GetDeviceIndexBuffer	Access the mesh's index buffer after it has been committed to the device with ID3DX10Mesh::CommitToDevice. This is different from ID3DX10Mesh::GetIndexBuffer, which returns the index buffer before it has been committed to the device.
GetDeviceVertexBuffer	Access the mesh's vertex buffer after it has been committed to the device with ID3DX10Mesh::CommitToDevice. This is different from ID3DX10Mesh::GetVertexBuffer, which returns the vertex buffer before it has been committed to the device.
GetFaceCount	Retrieves the number of faces in the mesh.
GetFlags	Access the mesh's creation flags.
GetIndexBuffer	Retrieves the data in an index buffer.
GetPointRepBuffer	Get the mesh's point rep buffer.
GetVertexBuffer	Retrieves the vertex buffer associated with the mesh.
GetVertexBufferCount	Get the number of vertex buffers in the mesh.
GetVertexCount	Get the number of vertices in the mesh. A mesh may contain multiple vertex buffers (i.e. one vertex buffer may contain all position data, another may contains all texture coordinate data, etc.), however each vertex buffer will contain the same number of elements.
GetVertexDescription	Access the vertex description passed into D3DX10CreateMesh. The vertex description describes the layout of the mesh's vertex buffers.
Intersect	Determines if a ray intersects with this mesh.
IntersectSubset	Determines if a ray intersects with a subset of this mesh.
Optimize	Generates a new mesh with reordered faces and vertices to optimize drawing performance.
SetAdjacencyData	Set the mesh's adjacency data.
SetAttributeData	Set the mesh's attribute data.
SetAttributeTable	Sets the attribute table for a mesh and the number of entries stored in the table.
SetIndexData	Set the mesh's index data.
SetPointRepData	Set the point rep data for the mesh.
SetVertexData	Set vertex data into one of the mesh's vertex buffers.
