Accumlation buffer

Recommended Posts

Is there a point to using this? Why would anyone implement something so slowwwww... I don''t have the best system - 2.0GHz, 512MB SDRAM (not DDR), 7500 Radeon... but I''d say I''m on the target machine for most devolpers, good... not great. Anyways, I get about .10fps running a demo that uses the accumlation buffer with 4 passes... that''s just not right... If someone needs to use accumlation what''s the advantage of using that over rendering to a texture?

acumulation buffers are only supported in hardware on Voodoo 4+ (the ''T'' buffer) and thats not directly, and I _think_ on the radeon 9500+ but I can''t remember quite right, it may have been something else.

so there is very little point using them. And modern techniques using the likes of render-to-texture and such can do pretty much anything you want to do with the acculumulation buffer anyway.
