Hi, you have to replicate what you did for the camera decorators for the viewports as well. So you need StereoBufferViewports, one for the left eye with
svpleft->setLeftBuffer(true); svpleft->setRightBuffer(false); svpleft->setCamera(cameraDecoratorLeft); and one for the right eye, with svpright->setLeftBuffer(false); svpright->setRightBuffer(true); svpleft->setCamera(cameraDecoratorRight); than add both viewports to the Window. Source/System/Window/testStereoDecor.cpp has some examples for reference. kind regards gerrit On Tue, 2014-11-25 at 15:48 +0100, Jörn Teuber wrote: > Hello everybody, > > I have a seemingly simple problem with OpenSG 1.8 (yes, I have to use > that version...) which I don't know how to solve: > I want to use a zSpace Monitor to render in 3D, so I need quad buffered > stereo.
