Precomputed Radiance Transfer Functions
D3DX supplies the following precomputed radiance transfer (PRT) functions:
- D3DXCreatePRTBuffer
- D3DXCreatePRTBufferTex
- D3DXCreatePRTCompBuffer
- D3DXCreatePRTEngine
- D3DXCreateTextureGutterHelper
- D3DXLoadPRTBufferFromFile
- D3DXLoadPRTCompBufferFromFile
- D3DXSavePRTBufferToFile
- D3DXSavePRTCompBufferToFile
- D3DXSHPRTCompSplitMeshSC
- D3DXSHPRTCompSuperCluster
For more information about using PRT, see Precomputed Radiance Transfer (Direct3D 9).
The D3DXSHxxx functions are also used for PRT spherical harmonic (SH) operations.
