[osg-users] Value of a variable in shaders?

[Sebastian Messerschmidt]

Hi,

Usually you can use the output-colors in case of a fragment shader to 
inspect the values per fragment. Rendering to a texture and inspecting 
the values in the image is also an option.

Another approach to display incoming/per state values is this nifty shader:

Appart from this, in case you're using a modern Nvidia-GPU and 
Visual-Studio:

Cheers
Sebastian
