Faiz, Please try this and let us know what you run in to (ideally via a gitlab merge request <https://gitlab.kitware.com/paraview/paraview/blob/master/CONTRIBUTING.md>so we can review, test and merge it easily) * views_and_representations.xml add new option for the SetServerStereoType property called "PassiveStereo" * vtkPVServerOptions::AddMachineInformation add new key for eye choice, it should default to both if not specified but accept "both" "left" or "right" * vtkCaveSynchronizedRendererers - save the local choice of both, left or right into an ivar in DefineDisplay as we do for DisplayOrigin, X and Y - add an accessor * vtkPVRenderView.cxx where we set the serverstereo type and if stereotype is PassiveStereo downcast the synchronized renderer into a cavesynchronizedrenderer get the choice from the ivar set the renderwindow's stereo type to VTK_STEREO_LEFT or RIGHT accordingly
