Most of the new, wizzbang graphics cards that are on the horizon can do dotproducts on texture combine operations. When are we going to see this functionality exposed in OpenGL?
The GeForce has it’s texture_combiners_NV extension, but thats going to be a dead end isn’t it? The magic letters ‘NV’ pretty much stitch that up don’t they?
What’s happening with the ATI Radeon? It can do the dot product operation in hardware and is exposed through DirectX (shudder). There isn’t any mention of it in the OpenGL SDK provided by them.
Does anyone here think the video card manufacturers and the ARB need sort this out soon? What’s everyone’s views on this subject?
