Virtools Stereo Frustum BB

This plugin will enable you to calculate a correct projection frustum for usuage in stereographics projection. It calculates an off-axis projection frustum from the Eyedistance and Focal distance in 3D. The plugin has been created for use in a passive stereoscopic setup. It's been created for a research about historical stereophotographics and stereographics for use in theatre performances. This research was initiated by Stichting Lange Poten. The plugin was written by Knip 'n Plak coder Wreck and myself. KnP Logo

Most of the techniques are based on documents from Paul Bourke.

Note that Virtools doesn't exist anymore. This page is just kept for historic purposes.

Just copy the DLL into your 'Building Blocks' directory. When you start Virtools you will find FrustumBB in section Cameras/FX:

Virtools Screenshot

This is the StereoFrustum Building Block in which you can set the following settings:

LeftEyePosition(boolean): should the left(true) or right(false) posistion be calculated
Eyedistance: The distance from 1 eye to the eyecenter. When using value 0 a workable distance will be calculated.
Focal: The distance from the camera to the focal point.

The Building Block outputs the eyedistance. This might be useful for parenting the camera to the eyecenter.
