Cg Shader Debugger Overview

Shader being debugged

Screen shows the

debug variable or expression

Choose the local variable to visualize

List the parameters and the visible

variables

The output RGBA channel mapping

Enter the expression to visualize

Determine the variable value for a

chosen pixel

Navigate the code to the next/previous
