Hi Stephen, The GeForce 6 series supports fp16 textures of the TEXTURE_2D variety, so you can use normalized [0,1] coordinates just like you do for all other...

Yes. It's true for NVIDIA, and I feel reasonably confident in saying it's true for ATI as well. Some rationale: EYE_LINEAR and SPHERE_MAP require...
