[osg-users] OSG to OptiX integration from 2012

[Uwe Woessner]

Hi Chris,

if you are looking for raytracing osg scenes in general and not OptiX
specifically, you could also have a look at
https://github.com/szellmann/visionaray
There is a visionaray plugin for OpenCOVER which is our OpenSceneGraph
based renderer. You find it here: https://github.com/hlrs-vis/covise

Regards,
 Uwe
