详细描述

Classic image-space anti-aliasing.

Modes:

  • "fxaa" — FXAA 3.11-style luminance edge search + subpixel blend
  • "smaa" — SMAA-inspired single-pass morphological AA (fits 1×MainTex post path)
  • "ssaa" — supersample resolve (box / tent / Gaussian); render into a larger Canvas first
  • "nfaa" — Normal Filter AA (blur along luma-gradient tangent)

Quality presets ("low" | "medium" | "high") tune thresholds / search / kernel radius. Workflow: render scene → Canvas → aa.apply / aa.applyTo → screen or next post.
