hy. I'have understand that gdevil don't debug cg shaders. What are the opensource and commercial project to debug cg shaders? In nvidia shader debugger i can start from an executable? if no how i can debug completely the shader? thanks

unfortunately there really is no way to do this.

It is a huge pain.

If you want to do the debugging yourself, the only (and obvious) solution is to make a FLOAT renderbuffer and output your value, then readback with glReadPixels.

Sig: http://glhlib.sourceforge.net
an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
