Method of [`Camera.views`](Camera.views.md) · stable · since 2.0.0 · called as `session.camera.views.go`

```ts
go(name: string, options?: CameraCommitOptions<C> & CameraMoveOptions): Promise<Report>;
```

A named view from the document ([`camera.views`](Camera.views.md)); a view write, as `set`, so a [`LookAtView`](LookAtView.md) sets the focal offset to zero. Errors: rejects HoloInputError 'unknown-id'.

## Options

Through [`Session`](Session.md):

| Option | Type | Default | What it does |
| --- | --- | --- | --- |
| `actor` | `Actor` | the `expectGroup`'s actor when one is given, else 'app' | Who made the write. |
| `durationMs` | `number` | 0 | 0 lands exactly, without damping, before the next frame. |
| `easing` | `Easing \| 'damped'` | 'easeInOut' | The move's time curve: an [`Easing`](Easing.md), or `'damped'`, a critically damped spring with no overshoot, which is 1.x's `transition: true` glide. |
| `expectRevision` | `number` | undefined (no check) | If-match on [`session.revision`](Session.revision.md). |
| `origin` | `string` | null | Your tag, echoed unchanged in [`Report.origin`](ReportFields.origin.md) and `cause.origin`. |
| `signal` | `AbortSignal` | undefined | Cancels this call; the member's JSDoc says what an abort does. |

Refused here (typed `never`, so passing one fails to compile): `dryRun`, `expectGroup`, `supersede`, `undo`.

Through [`Tx`](Tx.md):

| Option | Type | Default | What it does |
| --- | --- | --- | --- |
| `durationMs` | `number` | 0 | 0 lands exactly, without damping, before the next frame. |
| `easing` | `Easing \| 'damped'` | 'easeInOut' | The move's time curve: an [`Easing`](Easing.md), or `'damped'`, a critically damped spring with no overshoot, which is 1.x's `transition: true` glide. |
| `signal` | `AbortSignal` | undefined | Cancels this call; the member's JSDoc says what an abort does. |

Refused here (typed `never`, so passing one fails to compile): `actor`, `checkpoint`, `dryRun`, `expectGroup`, `expectRevision`, `origin`, `supersede`, `undo`.

## Abort (`signal`)

This call is a write (`SignalOption.signal`, [the kinds of call](../read-this-first.md#conventions)).

> A write: before the commit point it rolls back and rejects AbortError; after it, no effect, except that a running camera move stops where the last frame drew it (`CameraMoveOptions`).
>
> Through a `tx` the commit point is the transaction's: aborting a write still loading rejects AbortError and stages nothing (catch it: unobserved, it rolls the transaction back, spec section 6.1, O6); aborting one already staged unstages it, its paths keeping the latest other write to them as after a failed savepoint (O7), and its Promise stays resolved 'staged'.

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `go` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | pass: 5 apps (fleet cross-check: app-378d190f1b, app-4f16d2f6da, app-510d750508, app-ceb4eccc72, app-fb16dd1985) |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
