Thanks for help! I am setting the focal lense x and y with the following calls now and it seems to work fine:
double fovy = 2 * atan(this->_height / 2.0 / dFocalLengthY); double aspectRatio = this->_nWidth / this->_nHeight * dFocalLengthY / dFocalLengthX; double zNear = 0.1, zFar = 100.0; _viewer.getCamera()->setProjectionMatrix(::osg::Matrix::perspective(fovy, aspectRatio, zNear, zFar)); But i still can't set up the position and rotation of the viewer's camera. this->_viewer.getCamera()->setReferenceFrame(::osg::Transform::ABSOLUTE_RF); this->_viewer.getCamera()->setViewMatrix(::osg::Matrix::translate(0.5, 0.3, 0.1)); this does nothing. My guess is becase i also have to call: ::osg::ref_ptr< ::osgGA::KeySwitchMatrixManipulator> keyswitchManipulator = new ::osgGA::KeySwitchMatrixManipulator; keyswitchManipulator->addMatrixManipulator( '1', "Trackball", new ::osgGA::TrackballManipulator() ); this->_viewer.setCameraManipulator( keyswitchManipulator.get() ); or the offscreen capture doesn't render the scene, just an empty background. It looks like viewer needs a camera manipulator or it won't render the scene. Is it at all possible to move the camera programmatically after a camera manipulator has been set for the viewer? Or can i avoid creating a camera manipulator? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=34672#34672 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
