How can I debug CG shaders.

Dear experts,

I'm invetsingating on shader debugging with Cg+OpenGL.

If anybody give about their ideas it will be great help for me.

1) Is there any APIs get the current values of each variable in
shader ?
2) Is there any way to compile shader programmically and get the error
codes

Did you try FX Composer 2.5 ?

Bye,
Skybuck
