More on GLSL and OS 10.4 - ARB?

Thanks for all the replies. Yes, I’ve discovered there isn’t much publicly available information from Apple about their future plans. That’s a little irritating, because it means that we’re lacking some direction that we could well use on the project!

I’m still getting up to speed on OpenGL, so I don’t really know if we need 2.0 or 1.5–I’m guessing 1.5 is fine. I know that FBO would help immensely, but we can probably hack out something with pbuffers. As a stopgap measure I may also change gears and learn ARB shaders.

Which brings me to my next question: is there a good tutorial out there on ARB shaders? GLSL has a whole book, but ARB shaders seem to have the specification on SGI’s site, and not much else.

Any suggestions on how to learn this stuff?

It’s pretty straightforward. Try out the examples you find in the spec, take a look at the instruction reference in the OpenGL shader builder, etc.
