Hi everyone, I am fairly new to OSG and am trying to use slave cameras to view a scene from slightly different angles, of which will overlap slightly. I am starting with the OSG 3.0 Cookbook example from chapter 4, #2 (source code at https://github.com/xarray/osgRecipes). Instead of the full 9 cameras, I am working with just two cameras that I am aligning side by side, with no rotation as my first test, using the following approximate code. In this example, I am attempting to show half of a 3D model on each slave camera.
Slave1: osg::Matrix projOffset = osg::Matrix::translate(1,0,0); viewer.addSlave(camera, projOffset, osg::Matrix(), true); Slave2: osg::Matrix projOffset = osg::Matrix::translate(-1,0,0); viewer.addSlave(camera, projOffset, osg::Matrix(), true); This seems to work fine, with half the 3D model on the left screen, half on the right. When i add in a rotation term, for example, on slave 2: osg::Matrix projOffset = osg::Matrix::rotate(osg::DegreesToRadians(15), osg::Vec3D(0,1,0)) * osg::Matrix::translate(-.8,0,0); viewer.addSlave(camera, projOffset, osg::Matrix(), true); all I see is a tiny sliver of the model. I have tried rotating on different axis (placing the 1 in a different spot in the vector), different translations, etc. The Z axis seems to work fine, but the X and Y axis are not working properly. I am thinking it may be due to an improperly setup frustrum, but am having trouble setting it. I would appreciate any kind of information as to what I may be doing wrong or should be looking at. Thank you! Jim
