HI Thomas, The osgdistortion example sets up a render to texture slave camera that renders the scene along with inheriting the view matrix from the master Camera or the view, it uses a relative reference frame to achieve this. A second slave camera is used to a that has an absolure reference fram

Re: [osg-users] Trackball manipulator and screen distance with stereo

Hi Christian, Thank you very much for your answer! :D I can't override the virtual function (I don't know why, but it dont works) :O. However, I can change the value of _distance, and it doesn't change the other features. Thank you again! Cheers, Jon -- Read this topic online

Re: [osg-users] Trackball manipulator and screen distance with stereo

In my custom camera Manipulator I had to override the getFusionDistanceValue() function to get the desired effect. You can do the same by creating a child class of TrackballManipulator and use this instead. By default it returns _distance, which is the distance from the camera to the trackball cen

Hi Peter, If you want to set the home position of a manipulator then use the MatrixManipulator::setHomePosition(...) method. viewer.getCameraManipulator()->setHomePosition(...); Robert. On Wed, Jan 30, 2008 at 4:55 AM, Peter DeSantis <[EMAIL PROTECTED]> wrote: > > > Hello > > I may be wrong abo

[osg-users] trackball manipulator and axis alignment

Hello   I may be wrong about this, but it seems that if you set a modelview matrix to osg::matrix::identity(), and add it to the default viewer camera, osg axis alignemnt is changed to the opengl default, and the camera views the xy plane infront (so to speak)   but then adding a trackball
