Shader Conversion

• Babelshader
• http//graphics.stanford.edu/danielrh/babelshader
  .html
• Designed to convert between DirectX HLSL output,
  pixelshader 2.0 and OpenGL's low level shading
  languages
• Allows OpenGL programs to use Microsoft's stand
  alone HLSL compiler, fxc.exe to compile programs
  into ARB or fp30 assembly.
• Enables fair benchmarking competition between the
  HLSL compiler and the Cg compiler on the same
  platform with the same demo and driver.

Debugging Tools

• imdebug The Image Debugger
• http//www.cs.unc.edu/baxter/projects/imdebug/
• A programmer's utility to make debugging of Win32
  applications that use images and grid data
  easier.

Debugging Tools

• Shadesmith Shader Debugger
• http//graphics.stanford.edu/projects/shadesmith
• Debugger in the spirit of imdebug
• Simply add a debug statement when binding shaders
• Display window with scale, bias, component
  masking
• Advanced features
• Can watch any shader register contents without
  recompile
• Shader single stepping (forward and backward),
  breakpointing
• Shader source edit and reload without recompile

Utility Code

• RenderTexture
• Open Source http//gpgpu.sourceforge.net
• Convenience class for OpenGL render to texture
• Supports NVIDIA and ATI extensions
• Float pbuffers and textures supported
• Supports copy to texture (CTT) or render to
  texture (RTT)
• CTT only under Linux (no RTT extension yet)
• Supports render-to-depth-texture RTDT
• Supports pbuffers with multiple color buffers
