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;
Header: Declared in D3dx9mesh.h.
Import Library: Use D3dx9.lib.
