Cg Shader Debugger Overview

Navigate the code to the next/previous location Single pixel debugging mode Kill Fragment mode Special modes to help understand branches, loops, and function calls Choose the location at which to output the variable Shader being debugged List of functions in the shader List of shaders being debugged List the parameters and the visible variables Choose the local variable to visualize © NVIDIA Corporation 2007 Enter the expression to visualize The output RGBA channel mapping Choose the technique and pass to debug Determine the variable value for a chosen pixel Screen shows the debug variable or expression

Cg Shader Debugger Summary Shader debugging Debug CgFX and COLLADA FX Cg fragment shaders Debug multiple shaders at once Navigate the code using Shader Editor Visualize variable values Exciting Features Kill fragment: kill fragments that don’t reach the chosen location Debug individual pixels: Go to next or previous statement; Trace loops and branches; step into and out of function calls

Conclusion Most comprehensive Shader IDE Accessible to a wide user base Streamlined pipeline integration Advanced debugging and performance analysis
