Hi!
I'm wondering if there's any point in using glShadeModel and glLightModel functions while using shaders?
I've been looking through the docs and failed to get an answer.
I'm asking about OGL 2.1 but I'd be interested if the same applies to the newer versions.
thanks

Yes, glShadeModel has an effects since this controls how values are interpolated across a triangle.
As for lighting, you are suppose to do the lighting yourself in a vertex shader or fragment shader. All glLight functions are irrelevant including glLightModel.

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);
When you don't explicitly state it in the shader, that is.Yes, glShadeModel has an effects since this controls how values are interpolated across a triangle.
Ok. I think I understand. Thanks a lot
