No code sample on my part, maybe others have, but it's really not that difficult. :)
All OSG::Window:s have addPort(). Use that for your new viewport. Simlarly, Viewports have setCamera() and setBackground(). Setting up the orth-cam is pretty basic too if you want a simple 0,0 - 1,1 coordinate system. /Marcus On 2010-05-04 11:52, Haeyong Chung wrote: > I am using MultiDisplayWindow+SSM.
