Self Shadowed Bumpmaps
This projects includes all source and content for the self shadowing bump map algorithm presented at the 2001 GDC lecture by Dan Baker and Chas Boyd. This app will run without pixel shaders, as long as the hardware has rendertargets and DOT3. However, it runs much more efficently with pixel shaders and with better visual results.
Source files
main.cpp App main file
shadowset.cpp All the code for the self-shadowed bump map
d3dapp.cpp The App framework already included on the DX 8 sdk
d3dfont.cpp These files are provided for conveince only
d3dutil.cpp and should be replaced with newer files from the
dxutil.cpp sdk on newer releases of DirectX.
