<a href="https://threejs.org" target="_blank" rel="noopener">three.js</a> - Temporal Anti-Aliasing (TAA) pass by <a href="https://clara.io" target="_blank" rel="noopener">Ben Houston</a><br/><br/>
|
||
|
|
When there is no motion in the scene, the TAA render pass accumulates jittered camera samples<br/>
|
||
|
|
across frames to create a high quality anti-aliased result.<br/><br/>
|
||
|
|
Texture interpolation, mipmapping and anistropic sampling is disabled to emphasize<br/> the effect SSAA levels have one the resulting render quality.
