Hi Kim, I agree with Sebastian. However, if you are still interested in use CUDA in an OSG application, you can explore osgCompute library ( http://www.basementmaik.com/doc/osgcompute/html/). In addition, in the osgCompute webpage you can find http://www.cg.informatik.uni-siegen.de/data/Publications/2009/orthmann09osgcompute.pdf. Maybe it is useful in order to give you a general idea.
