Contour Atlas
Contour Atlas is a procedural ShaderWeave generator: describe the look in JSON, choose a seed, and render png, webp. It runs in the browser editor and through the rendering API, so a recipe you tune by hand can be reused in a build step or by a coding agent.

What it gives you.
- Deterministic output — the same recipe, seed and engine version produce byte-identical pixels.
- Exports png, webp from one recipe.
- Available in the editor, the REST API, the MCP server and the CLI.
- Tune colors, scale, contours, warp, lineWidth, relief and more with schema-driven controls.
Parameters.
Contour Atlas exposes these parameters. Every value is validated against the generator’s published JSON schema before a render starts.
- colors
- scale
- contours
- warp
- lineWidth
- relief
- paper
Formats and credit cost.
- png
- webp
Still images cost one credit per output megapixel. Animation costs ten credits per megapixel per second. SVG and CSS output costs one credit.
| Example output | Credits |
|---|---|
| Full HD image · PNG | 3 |
| Full HD image · WebP | 3 |
Call it from an API.
curl -s -H "Authorization: Bearer $SHADERWEAVE_API_KEY" \
-H "Content-Type: application/json" \

Where it works.
Patterned surfaces
Use pattern fields as backgrounds for cards, covers, packaging and UI surfaces.
Data and dashboard decoration
A seeded pattern gives empty states and headers structure without hand-authored assets.
Batch asset generation
Render a set of variants through the API and compare the exported images to choose a direction.
Questions.
- How many credits does a Contour Atlas render cost?
- Stills cost one credit per output megapixel and animations cost ten credits per megapixel per second. Full HD image · PNG is 3 credits; Full HD image · WebP is 3 credits.
- Can I use Contour Atlas output commercially?
- Yes, on a paid plan. Free-plan exports are for evaluation and non-commercial use, and the free plan does not include API access.
- Can I call Contour Atlas from an API or a coding agent?
- Yes. POST /v1/generate/contour-atlas with a bearer API key renders synchronously, POST /v1/jobs queues an animation, and the MCP server exposes the same generator to coding agents. API access requires a paid plan.
- Is Contour Atlas output reproducible?
- Yes. A render is a pure function of the generator, its parameters, the seed and the engine version, so re-running the same recipe returns the same image later.
