# camera3D

[Built-ins](README.md)

Canonical ID: `scene3d.camera`. Nederlands: `camera3D`.

Sets the camera to an absolute world position and preserves yaw (the left-or-right angle) and pitch (the up-or-down angle). Placement is explicit and can place the camera inside an object; it does not run movement collision checks. The initial camera is (0,1.5,5), facing -Z. Use lookAt3D afterward when you want it to point at a particular world target.

See [3D words and camera rules](../guides/scene3d.md).

## Signature

```text
camera3D(x, y, z)
```

## Arguments

| Parameter | Type | Requirement |
|---|---|---|
| `x` | Number | Finite world coordinate, absolute value at most 10,000. |
| `y` | Number | Finite world coordinate, absolute value at most 10,000. |
| `z` | Number | Finite world coordinate, absolute value at most 10,000. |

## Return value

`None`.

## Example

```pliro
# language: en
clear3D("#16213e")
box3D("box", 1, 1, 1)
camera3D(3, 2, 5)
lookAt3D(0, 0, 0)
draw3D()
```

An angled view of the box at the origin.

## Notes and common mistakes

Use the function name for your source language. Its [canonical ID](../concepts/canonical-identity.md) is a shared documentation label; you do not type that ID as a call. Giving your own variable or function the same name can hide the built-in. Supply the documented [arguments](../concepts/parameters-and-arguments.md) and value types. Pliro reports mismatches when checking can detect them, or when the call runs.

A **host** is the app or environment running your program. To see a drawing, it needs a **renderer**, the part that draws on screen. The [command-line](../concepts/command-line.md) command `pliro run` shows text but does not draw these graphics. The [host support table](../guides/hosts.md) explains which effects work in the IDE, browser, native app, and phone preview. A native build reports an unsupported capability instead of leaving it out.

In 3D, +Y points up. **Yaw** is the left-or-right angle; at zero the camera faces -Z. The world holds at most 256 objects. Changes appear when you call `draw3D`. An invalid call leaves the world unchanged. Editing requires an existing object name; creating objects and removing an absent name are exceptions. Use the [portable color names or hex codes](../guides/colors.md); transparent colors are unavailable here. Version 1 of the phone preview's communication format does not carry 3D scenes. See the [3D guide](../guides/scene3d.md) for the coordinate rules.
