Have a look at the source to org.j3d.terrain.ViewFrustum oin the j3d.org code respotiory (http://code.j3d.org). It basically starts with a simple unit cube and then "scales" the 6 planes that define the unit cube by the projection matrix from the left eye to give the real view frustum definition. -- Justin Couch http://www.vlc.com.au/~justin/ Java Architect & Bit Twiddler http://www.yumetech.com/ Author, Java 3D FAQ Maintainer http://www.j3d.org/ ------------------------------------------------------------------- "Humanism is dead.
