I see, thank you. I guess that I will have to put this idea to rest then.

The Z buffer and frame buffer certainly share separate address space, what do you mean when you say that the Z-buffer is part of the framebuffer?

Anyway, thanks for the answer. I may have to...

Be default, I believe that when an alpha test fails, neither the frame buffer nor the Z buffer are updated. However, I wish to change this behavior arbitrarily. For example, when an alpha test fails,...

I have been reading about shaders and I have found an interesting article, here, as well as this. Both of which demonstrate the manipulation of textures using fragment shaders. I will need to learn...

What I really need is a way to set aside an amount of memory in the GPU which will act as the PS2's GS memory. This can easily be done with glTexImage, but the issue is that using this method that...

The first method sounds perfect, and I believe that is actually how other plugins for PS2 emulators (such as ZeroGS) do it. However, I am not at all familier with OpenGL's shaders, could someone...

Hi OpenGL forum.
I'm writing a graphics plugin for PS2 emulators and i've got to the point where I want to efficiently emulate textures. Before I ask the question, I just want to give a brief...
