Hi Bob,
The viewer only renders a frame when you call viewer.frame(). If you are
calling the convenience function viewer.run() then just replace this run
call with the constuent parts of Viewer::run() i.e.
while(!viewer.done())
{
viewer.advance();
viewer.eventTraversal();
viewer.updateTraversal();
viewer.renderingTraversals();
}
Robert.
