glslDevil – OpenGL GLSL Debugger

For those of you working with OpenGL Shaders via GLSL, the freely available glslDevil tool offers a great way to interactively debug and manipulate these shaders kn real-time on both Windows and Linux.

glslDevil is a tool for debugging the OpenGL shader pipeline, supporting GLSL vertex and fragment programs plus the recent geometry shader extension. By transparently instrumenting the host application it allows for debugging GLSL shaders in arbitrary OpenGL programs without the need to recompile or even having the source code of the host program available. The debug data is directly retrieved from the hardware pipeline and can be used for visual debugging and program analysis.

Binaries are available at their site.  I’m not sure, how prevalent is GLSL in the wake of new technologies?
