$npx -y skills add scottstts/Threejs-Awesome-Graphics-Agent-Skills --skill threejs-screen-space-ambient-occlusion

Installs into the current project.

Summary

Implement a production GTAO path in Three.js. Use for half-resolution horizon sampling, reversed-depth reconstruction, bent-normal encoding, full-resolution bilateral reconstruction, environment-light application, contact grounding, and halo diagnosis.

1	# Screen-Space Ambient Occlusion
2
3	AO estimates missing ambient visibility. It must modulate indirect lighting, not repaint all scene color with a dark multiply.
4
5	## Workflow
6
7	1. Verify linear depth and view-space normals.
8	2. Reconstruct view position consistently.
9	3. Sample horizon visibility in a controlled radius.
10	4. Estimate AO and optional bent normal.
11	5. Denoise with depth/normal-aware filters.
12	6. Apply to indirect diffuse and environment response.
13
14	Read [references/gtao-bent-normal-pipeline.md](references/gtao-bent-normal-pipeline.md).
15
16	## Failure conditions
17
18	- direct light and emission are darkened;
19	- radius is specified only in pixels;
20	- foreground silhouettes cast thick screen-space halos;
21	- depth discontinuities are blurred together;
22	- AO remains strong at distances where its world radius is subpixel;
23	- bent normals are treated as ordinary geometric normals;
24	- the implementation claims temporal accumulation even though this path has none.
25
26	## Routing boundary
27
28	This skill owns GTAO gathering, bent normals, denoising, and AO application.
29	Use `$threejs-image-pipeline` only when its depth/normal buffers or pass order
30	must be coordinated with other image-space systems.
