One master machine and three slave machines are devoted to control it. Each slave machine has the same system to master(replica), and have to control 2 LCDs in a column. Since a slave machine deals with 2 LCDs as a fullscreen space, I think my approach is similar to what you want to do. Here is my code to shear viewport of each slave machine. I hope it is helpful to your project ============================================== // get current view frustum double fLeft, fRight, fTop, fBottom, fNear, fFar = 0.0; viewer.get()->getCamera()->getProjectionMatrixAsFrustum( fLeft, fRight, fBottom, fTop, fNear, fFar ); // View frustum for right two LCDs in a column if( actOpt.m_eViewLinkPosition == RIGHT ) // please don't care about this viewer.get()->getCamera()->setProjectionMatrixAsFrustum( fRight/2, fRight, fBottom, fTop, fNear, fFar ); // View frustum for left two LCDs in a column else if( actOpt.m_eViewLinkPosition == LEFT ) viewer.get()->getCamera()->setProjectionMatrixAsFrustum( fLeft, fLeft/2, fBottom, fTop, fNear, fFar ); // View frustum for center two LCDs in a column else if( actOpt.m_eViewLinkPosition == CENTER ) viewer.get()->getCamera()->setProjectionMatrixAsFrustum( fLeft/2, fRight/2, fBottom, fTop, fNear, fFar ); ------------------------ VR Lab, Konkuk University, South Korea ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=22807#22807 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
