# MDLStereoscopicCamera

A point of view for rendering a stereoscopic display of a 3D scene.

```
class MDLStereoscopicCamera
```

## Overview

This class provides properties related to rendering the scene from two slightly different perspectives to simulate binocular vision. For general and optical properties of a camera, see the superclass [`MDLCamera`](/documentation/ModelIO/MDLCamera).

## Topics

### Modeling Stereoscopic Imaging

[`interPupillaryDistance`](/documentation/ModelIO/MDLStereoscopicCamera/interPupillaryDistance)

The distance, in millimeters, between the stereoscopic camera’s two viewpoints.

[`overlap`](/documentation/ModelIO/MDLStereoscopicCamera/overlap)

The amount, as a fraction of image width, by which the images from the camera’s two viewpoints overlap.

[`leftVergence`](/documentation/ModelIO/MDLStereoscopicCamera/leftVergence)

The angle, in degrees, at which the camera’s left viewpoint faces toward a central focal point.

[`rightVergence`](/documentation/ModelIO/MDLStereoscopicCamera/rightVergence)

The angle, in degrees, at which the camera’s right viewpoint faces toward a central focal point.

### Generating View and Projection Matrices

[`leftViewMatrix`](/documentation/ModelIO/MDLStereoscopicCamera/leftViewMatrix)

The transformation matrix that determines the position and orientation of the camera’s left viewpoint relative to a scene.

[`leftProjectionMatrix`](/documentation/ModelIO/MDLStereoscopicCamera/leftProjectionMatrix)

The transformation matrix that determines the extent of a scene visible to the camera’s left viewpoint.

[`rightViewMatrix`](/documentation/ModelIO/MDLStereoscopicCamera/rightViewMatrix)

The transformation matrix that determines the position and orientation of the camera’s right viewpoint relative to a scene.

[`rightProjectionMatrix`](/documentation/ModelIO/MDLStereoscopicCamera/rightProjectionMatrix)

The transformation matrix that determines the extent of a scene visible to the camera’s right viewpoint.
