D3DXCreatePRTEngine function
Creates an ID3DXPRTEngine object that can efficiently generate precomputed radiance transfer (PRT) simulations of a 3D scene.
Syntax
HRESULT D3DXCreatePRTEngine(
_In_ LPD3DXMESH pMesh,
_In_ DWORD *pAdjacency,
_In_ BOOL ExtractUVs,
_In_ LPD3DXMESH pBlockerMesh,
_Inout_ LPD3DXPRTENGINE ppEngine
);
Parameters
-
pMesh [in]
-
Type: LPD3DXMESH
Pointer to an input ID3DXMesh mesh object that models the 3D scene. This mesh must have an attribute table in which vertices are in a unique attribute.
-
pAdjacency [in]
-
Type: DWORD*
Optional pointer to an array of three DWORDs per face to be filled with adjacent face indices. The number of bytes in this array must be at least ((3 * GetNumFaces) * sizeof(DWORD)). May be NULL.
-
ExtractUVs [in]
-
Type: BOOL
If TRUE, textures will be used to store albedos or PRT vectors.
-
pBlockerMesh [in]
-
Type: LPD3DXMESH
Pointer to an optional ID3DXMesh mesh object that blocks the 3D scene. May be NULL.
-
ppEngine [in, out]
-
Type: LPD3DXPRTENGINE
Pointer to an output ID3DXPRTEngine object.
Return value
Type: HRESULT
If the function succeeds, the return value is D3D_OK. If the function fails, the return value can be one of the following: D3DERR_INVALIDCALL, E_OUTOFMEMORY.
Remarks
Use D3DXConcatenateMeshes to combine multiple meshes into a single mesh interface.
