# 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.
|
|
|
|
```ts
|
|
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]);
|
|
```
|
|
|
|
<Playground example="post" />
|
|
|
|
Every effect is optional:
|
|
|
|
```ts
|
|
await ssao.setEnabled(false);
|
|
await grade.update({ toneMap: "reinhard" });
|
|
await fxaa.dispose();
|
|
```
|
|
|
|
Also available:
|
|
|
|
```ts
|
|
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.
