I did something similar a very long time ago with OSG. I set the ModelView and Projection matrix of the SceneView directly:
setProjectionMatrix( _mtx_proj ) setViewMatrix(vmtx) for model view you would calculate matrix::makeLookAt and for the projection matrix you need to compute your frustum. Depends on the application how you set these up. OSGers-- I'm talking *very old versions* of OSG-- is there now a bundled 'convenience' class that takes care of this monkey business? t On Tue, Mar 2, 2010 at 6:09 PM, Mel Av <melinos...@hotmail.com> wrote: > Hey, > > I was wondering if anyone knows what would be the best solution for > building an application where the camera is headtracked using motion > captured data provided in realtime from a Vicon system in OpenSceneGraph.
