# Getting Started with Endoscope

> Enter and exit the virtual endoscopy view

## Entering Endoscope Mode

1. **Ensure segmentation is complete** — Run segmentation first if you haven't already.
2. **Click the Endoscope button** in the toolbar — this enters **picking mode**.
3. **Click on a mesh surface** — this sets the entry point for the endoscope camera.
4. The endoscope view activates, showing the first-person perspective from your chosen entry point.

## Picking Mode

After clicking the Endoscope button, you're in picking mode:

* The cursor changes to a crosshair.
* Click on any mesh surface to set the entry point.
* The camera will be positioned at the surface and oriented inward.

## Exiting Endoscope

You can exit the endoscope in two ways:

* Click the **Stop** button in the endoscope controls.
* Click the **Endoscope** button in the toolbar again.

## Changing Entry Point

While in endoscope mode, you can reposition your entry point using the **Entry Nudge** controls (see [Camera Controls](/endoscope/camera-controls)).
