Provide the single-loadout Scene API, SAB-backed meshes, cameras, materials, lights, workers, post effects, and tutorial playgrounds. Batch matching row growth so active GPU loadouts refresh once.

Post processing
Post-process handles insert or remove graph passes. Intermediate HDR textures are transient and compatible non-overlapping lifetimes alias the same physical allocation.
const ssao = new SSAO(scene, { amount: 0.8 });
const exposure = new DynamicExposure(scene, { exposure: 1.1 });
const grade = new ColorGrading(scene, { toneMap: "aces", amount: 1.0 });
const fxaa = new FXAA(scene);
await Promise.all([ssao.ready, exposure.ready, grade.ready, fxaa.ready]);
Every effect is optional:
await ssao.setEnabled(false);
await grade.update({ toneMap: "reinhard" });
await fxaa.dispose();
Also available:
const outline = new Silhouette(scene, { amount: 1 });
const edgeImage = new Edges(scene, { amount: 2, enabled: false });
await edgeImage.setEnabled(true);
The final present pass tone-maps HDR to the canvas. ColorGrading supports aces, reinhard, and linear tone maps.
