First frame of the TAA is just a regular copy of the previous buffer. so
we write directly to the final buffer and skip the taa shader. We do
init the history buffer via blit so it will be initialized for the other
iterations.
- TAA is also enabled for Forward rendering
- Uses less GPU memory (removed one history buffer)
- TAA is done after the color management
- consolidated the aa code between forward and deferred rendering
(workbench_effects_aa.c)
Currently only attached to the Anti Aliasing of the solid mode of the
viewport. But eventually we could add other options here. Quality
setting can be found in the System tab of the userpref.
The slider goes from No Antialiasing (0.0 - 0.1) to FXAA (0.1 - 0.25) to
TAA8 (0.25 - 0.6) to TAA16 (0.6 - 0.8) to TAA32 (0.8 - 1.0)
- FXAA is now also done in the workbench_forward engine.
- User can enable TAA8 in the userpref by setting their max
viewport AA to TAA8. FXAA will still be used when navigating
