Torben, That's good news about the CiGi module. If this gets completed, I will be very interested in looking at osgVisual for our host.
On the distortion correction, is there really any need for pixel level distortion? That would seem very expensive. I would think that textureCoodinate distortion is more than sufficient with a reasonable mesh resolution. I haven't seen the need for pixel level distortion in a spherical dome display. Does osgVisual support an interface for providing asymmetric viewing frustums for each channel? What I mean by this is can I specify the clipping bounds (i.e. rotation, widening or shrinking) for each channel frustum so that I can effectively tile the channels in a dome display optimally? How does osgVisual deal with edge blending of the channels or do you rely on the projectors to do this?

We have already a 6 channel helicopter simulator with a specrical screen working with that software, only the manual setup via mouse is not working yet. Here are some images: http://www.osgvisual.org/projects/osgvisual/chrome/site/img/distortionNG 1.jpg http://www.osgvisual.org/projects/osgvisual/chrome/site/img/distortionNG 2.jpg http://www.osgvisual.org/projects/osgvisual/chrome/site/img/distortionNG 3.jpg The CiGi-Module for multichannel communication is under construction currently, we hope to finish this autumn. Do you want to use vertex distortion of the Mesh, textureCoordinate distortion of the RTT-Output or pixel wise distortion?
