# `math.projection.project`

> Contract 2.0.0 · package sha256 `a857eca95b35921109faf997094bb4192f12527d9d0fcd4be7e97f06425bad6e` · generated from `math.d.ts` by `services/onsite-scripter/scripts/build-contract-docs.mjs`; edit the source, not this file.

Method of [`math.projection`](math.projection.md) · labs, `@experimental` · since 2.0.0

```ts
project(camera: {
  view: CameraView | LookAtView;
  size: {
    width: number;
    height: number;
  };
  fovDeg?: number;
  horizontalFovDeg?: number;
}, points: readonly Point3[]): Array<ProjectedPoint | null>;
```

`points` as [`camera.project`](Camera.project.md) would place them through `camera.view` in an image of
`camera.size` CSS px: x and y from its top-left, `depth` metres along the view, `visible`
when in front and inside. Null for a point behind the camera, and for every point when the
size is not positive or a [`LookAtView`](LookAtView.md)'s `position` is its `target`.

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `project` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | labs (`@experimental` at a stable path, reached through `has()` or `supports()`): it graduates when a second app uses it |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
