have a look here: http://www.starstonesoftware.com/OpenGL/mac.htm

Example of openGL code 3.x + on OSX
There are example of how you can recode 1.4 to 1.1 GLSL.

I would convert all of the values to integers and see if there is a sampler for reading in ivec4 instead of vec4. I couldn't use floating point textures though. In OpenGL 3.x they introduced shift operations and modulo as well as bit masking.


Check if EXT_gpu_shader4 is supported on your Mac. If it is, you should be able to use bitwise operations withoug OpenGL 3.

I'll probably get MacOSX 10.7 for my birthday. It has OpenGL 3 support but only in software.

Update:

Along the way to my quest, I discovered that MrgCop() and RethinkDisplay() are inadequate to the task of providing a gateway to Copper emulation. They depend too much on the base Copper-list pointed to by the ViewPort structure. It seems they only work in trivial cases such that only color-change copper lists would work well and anything non-trivial will not work (eg. changing bitplane pointers relative to the top of an Intuition-scrolled screen).

I hoped the X1000 will be able to emulate the NatAmi using this GPU acceleration, but I kind of doubt that there will be sufficient time and energy to write a NatAmi emulator before it comes out anyway.

I was think about doing a Effects library of some sorts, some thing that can easy do the old effects, but is not trying to do the P2C because that's just a wast of CPU, and use Composition for scaling.

At lest that's doable, the question is if anyone is going to use it, if I do.
