Support in HW, or support at all?
No consumer-level hardware supports accumulation buffers in HW.
But every OpenGL driver I know of supports accumulation buffers, at least in SW. It’s required to pass the conformance tests, so if it doesn’t work, the driver is not an OpenGL driver…
Both Voodoo5 and Radeon supports accumulations buffers.
Not in hardware, they don’t… no consumer-level 3D hardware today supports accumulation buffers in HW. It’s simply a feature that people have decided is not worth it, at least for now.
Humus, are you talking about the T-Buffer in the Voodoo? I know it can be used for some accum. operations. I don’t know if it could be used as a ‘full’ accumulation buffer.
Even if it could be, I doubt that 3dfx would spend the time on the OpenGL driver for it
