# Stereoscopic Rendering

This is a technical preview on how stereoscopic rendering could work in Qt 3D Studio.

Stereoscopy is a technique that adds the illusion of depth to a flat image. Special glasses or stereoscopic displays are needed to view stereoscopic images.

## Use Stereoscopic Rendering

To enable stereoscopic rendering, follow the steps below:

1. Run your presentation in the Viewer.
2. Select the desired stereo mode from View > Stereo Mode in the menu bar. Select Mono to disable stereoscopic rendering.

You can decrease or increase camera separation from View > Stereo Mode or by using shortcut keys Ctrl + Shift + - and Ctrl + Shift + +

## Stereo Modes

The following stereo modes are available.

### Top-Bottom

Render two images, one for each eye, one above the other.

### Left-Right

Render two images, one for each eye, side-by-side.

### Anaglyph

Render two differently colored images, one for each eye. Supported anaglyph glasses are Red-Cyan and Green-Magenta.

## Known Limitations

In this technical preview of stereoscopic rendering the following limitations are known:

- All layers should match the presentation size. Stereoscopic modes do not duplicate layers to both eyes, instead it duplicates the content inside layers. Layers smaller than the presentation will not render correctly in top-bottom and left-right stereoscopic modes.
- Because of above mentioned layer size issue and performance impact, presentations with sub-presentations do not fully work in stereoscopic modes.
- Currently, layer effects are not supported in stereoscopic modes. Effects will be disabled when using any stereoscopic mode.
