# What is an Arc Camera?

***Arc Rotate Camera***  acts like a satellite in orbit around a target and always points towards the target position. In our case, it is pointing towards the box. Where ever you move your camera, it will still point to towards the box. 

Arc Rotate Camera parameters are: **name** you want to give to your camera, **alpha**(radians) the longitudinal rotation, **beta** *beta* (radians) the latitudinal rotation, **radius(**the distance from the target position), **target position**(center where the box will be created as a default), **scene**(optional argument). In this code example scene is not given as an argument and defaults to the scene object on the playground.

{% hint style="info" %}
 Setting *beta* to **0** or **PI** can, for technical reasons, **cause problems.**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.xrdev.app/mixed-reality-docs/webxr-lessons/babylon.js/project/what-is-an-arc-camera.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
