Hi Glenn, Are you still embedding your .NET control in a Window Form Control? If so, how are you accomplishing this?
In the Producer days, one could just call viewer.setWindow with the window handle to the control, but I can't find an equivalent using the new osgViewer classes. The slave camera approach that Hesicong posted was the closest I could find. Thanks! Jason On Wed, May 28, 2008 at 1:25 PM, Glenn Waldron <[EMAIL PROTECTED]> wrote: > Jason, > > Afraid not.
