ID3DXPatchMesh Interface

This interface encapsulates patch mesh functionality.

ID3DXPatchMesh Members

CloneMesh	Creates a new patch mesh with the specified vertex declaration.
GenerateAdjacency	Generates adjacency information based on mesh indices.
GetControlVerticesPerPatch	Gets the number of control vertices per patch.
GetDeclaration	Gets the vertex declaration.
GetDevice	Gets the device that created the mesh.
GetDisplaceParam	Gets mesh geometry displacement parameters.
GetIndexBuffer	Gets the mesh index buffer.
GetNumPatches	Gets the number of patches in the mesh.
GetOptions	Gets the type of patch.
GetPatchInfo	Gets the attributes of the patch.
GetTessSize	Gets the size of the tessellated mesh, given a tessellation level.
GetVertexBuffer	Gets the mesh vertex buffer.
LockAttributeBuffer	Lock the attribute buffer.
LockIndexBuffer	Lock the index buffer.
LockVertexBuffer	Lock the vertex buffer.
Optimize	Optimizes the patch mesh for efficient tessellation.
SetDisplaceParam	Sets mesh geometry displacement parameters.
Tessellate	Performs uniform tessellation based on the tessellation level.
TessellateAdaptive	Performs adaptive tessellation based on the z-based adaptive tessellation criterion.
UnlockAttributeBuffer	Unlock the attribute buffer.
UnlockIndexBuffer	Unlock the index buffer.
UnlockVertexBuffer	Unlock the vertex buffer.

Remarks

A patch mesh is a mesh that consists of a series of patches.

To obtain the ID3DXPatchMesh interface, call the D3DXCreatePatchMesh function.

The LPD3DXPATCHMESH type is defined as a pointer to the ID3DXPatchMesh interface, as follows:

typedef struct ID3DXPatchMesh *LPD3DXPATCHMESH;
