Hi Zachary,
You can use the GraphicsWindowEmbedded class in conjunction with an
osgViewer to use the .NET wrappers. I'm attaching an example control that
uses Tao that seems to work for me pretty well.
If the particle system/transform issue that I posted on the osgDotNet trac
website gets fixed, I'm very happy so far with the wrappers. Just about
everything sensible I've tried "just works" the way I thought it should.
Thanks!
Jason
