Chapter 20: StereoCamera

Core Idea

A special type of camera that uses two perspective cameras with stereoscopic projection. Can be used for rendering stereo effects like 3D Anaglyph or Parallax Barrier.

Key Concepts

• aspect : number: The aspect.
• cameraL : PerspectiveCamera: The camera representing the left eye. This is added to layer 1 so objects to be rendered by the left camera must also be added to this la…
• cameraR : PerspectiveCamera: The camera representing the right eye. This is added to layer 2 so objects to be rendered by the right camera must also be added to this …
• eyeSep : number: The eye separation which represents the distance between the left and right camera.
• type : string (readonly): The type property is used for detecting the object type in context of serialization/deserialization.

Constructor

Signature
new StereoCamera()

Properties

Property	Description
.aspect : number	The aspect.
.cameraL : PerspectiveCamera	The camera representing the left eye. This is added to layer 1 so objects to be rendered by the left camera must also be added to this layer.
.cameraR : PerspectiveCamera	The camera representing the right eye. This is added to layer 2 so objects to be rendered by the right camera must also be added to this layer.
.eyeSep : number	The eye separation which represents the distance between the left and right camera.
.type : string (readonly)	The type property is used for detecting the object type in context of serialization/deserialization.

Methods

Method	Description
.update( camera : PerspectiveCamera )	Updates the stereo camera based on the given perspective camera.

Key Takeaways

1. Most relevant properties: aspect, cameraL, cameraR, eyeSep.
2. Key methods: update.
