Basic TAA #35

Closed codeonwort closed 2 years ago

codeonwort commented 2 years ago

Summary

Was going to implement HRAA in GPU Pro 6, but basic TAA was enough for current demo scenes.

References:

SIGGRAPH 2014: HIGH-QUALITY TEMPORAL SUPERSAMPLING

Reserve HRAA for future until more advanced AA is needed.

Sidenote for HRAA

GPU Pro 6: Hybrid Reconstruction Antialiasing

To implement HRAA, following GL extensions may be required:

NV_explicit_multisample
NV_sample_locations
AMD_sample_positions

RTX 3080 Ti supports (1) and (2), Ryzen 6800U supports (1) and (3).
