Hi Milos,
Hi, I have problem to set field of view od second slave camera. I used it like lens, but when I on lens camera, distance of my "grapf" is incorect. My lens camera is smaler as you can see in the pic. Lens option: osg::ref_ptr<osg::Camera> lensCamera = new osg::Camera; lensCamera->setCullMask(0x2); lensCamera->setGraphicsContext(viewerWidget >getGraphicsWindow()); lensCamera->setViewport(new osg::Viewport((viewerWidget->width()/4),(viewerWidget->height()/4),viewerWidget->width()/2,viewerWidget->height()/2)); lensCamera->setReferenceFrame(osg::Transform::RELATIVE_RF); viewerWidget->addSlave(lensCamera.get(), osg::Matrix(), osg::Matrix(), true); I tried something like this : viewerWidget->addSlave(lensCamera.get(), osg::Matrix::scale(2,2,2),osg::Matrixd()); but scale doesnt work. Anyone help me?
The second parameter of the addSlave is the translation offset. You need to change your slave's frustum by scaling the projection:
viewerWidget->addSlave(lensCamera.get(),osg::Matrixd(),osg::Matrix::scale(2,2,1.0)) Cheers Sebastian
Thank you!
