Light field is the set of light rays flowing through a point, surface or volume from every direction. Light field capture seizes all of the information about those rays of light. Using the information, you can generate an image that can be viewed from any direction. You can also generate a stereoscopic image, an image for each eye to create an 3D effect. For example, imagine an apple in the middle of a room. With light field capture, you can view the apple from any angle, top to bottom and front to back. With regular photography you can only view the apple from one direction.

With these properties, light field capture has great possibilities in Virtual Reality. It can be used to create live action, VR environments in real time.

OTOY was the first company to demonstrate light field capture for Virtual Reality.[1]
