Multi Display Support

Bino supports basic and advanced multi display video output options.

For basic multi display output, all displays must be connected to the same computer and run in fullscreen mode. This is useful for video walls or 3D projection systems that use separate projectors for the left and right view.

For advanced multi display output, Bino can use the Equalizer framework for parallel and distributed OpenGL rendering.
Equalizer can manage very flexible setups across multiple hosts, graphics cards, and/or displays. This is useful for larger display installations, for example large Powerwalls or Virtual Reality laboratories.


Example

This example shows the Big Buck Bunny movie in the Virtual Reality laboratory of the Computer Graphics Group at University of Siegen, Germany.

Bino displaying a video in a Virtual Reality installation

The display wall is divided into a left and a right part, with an overlap area for smooth blending. Two projector pairs project the video onto these left and right parts using Infitec stereo projection. Each projector pair is connected to a render node equipped with two graphics cards. Additionally, the video is displayed on the control node monitor shown on the right. The control node handles user input and takes care of audio output.

In this example, Equalizer takes care of running Bino synchronized across three computers, with a total of five video output windows (two for each stereo area, plus one control window).
