TRAA vs SMAA Comparison (r183 roadmap)
Split-screen anti-aliasing comparison with temporal accumulation AA on the left and SMAA post-processing on the right for visual quality tradeoff analysis.
Key topics: three.js traa, temporal aa, smaa, anti-aliasing comparison, post-processing
Game Over
What this code does
- Split-View Analysis: left half renders temporal accumulation AA (TRAA-style approximation), right half renders SMAA.
- Temporal Accumulation: combines current jittered frame with history buffer using configurable history weight.
- SMAA Reference: uses `SMAAPass` through `EffectComposer` as a crisp spatial anti-aliasing baseline.
- Motion Stress Test: animated high-frequency wireframe geometry exposes differences in shimmer, blur, and edge stability.
- Practical Use: helps evaluate AA strategy tradeoffs between temporal stability and fine detail sharpness.
