I am wondering is it possible to support GLSL on a Mac Mini with the current 9200 GPU??? I see some of the extensions that are needed for GLSL are supported by the 9200 but haven't heard anything offical.

Support is of course possible via software rendering.... however, even partial fragment shader support requires a Radeon 9500 or GeForce FX, so no. That said, it would be possible for the Radeon 9200 to accelerate GLSL vertex shaders. I guess we'll just have to wait and see what Apple does.

Well, fragment shaders definitely work on my card in Unity/Gooball. This is on a 9200 Mobility. I believe Unity uses the Cg toolkit. So it is probably working via ATI_text_fragment_shader . I'd imagine glsl requires the more robust (from what I hear) ARB_fragment_program/shader.

Yeah I thought I heard or read somewhere the FP/VP were needed to support GLSL due to it calls down to them sometime... Oh well I guess I will wait for the next PM update...

The Radeon9000 series support on GooBall uses Cg for vertex programs and hand coded ATI_TEXT_FRAGMENT_SHADER programs for the pixel shaders

Edit: The Radeon9000 series of cards can not support GLSL in hardware - no matter what apple does ;-)
