osg::Image* img = osgDB::readImageFile("name"); unsigned char pixel = img->data( x, y ); But as Pierre says, OSG offers a lot of support for rendering Height field data out of the box. It's worth digging around before reinventing the wheel as OSG has usually got there first. Regards, Kim. 200

Hi Eric, as far as I know there is no direct access to these cameras. Usually you don't have to implement stereo by yourself. You can just pass a few arguments to osgviewer to enable stereo. After all I have to admit that I'm not familiar with osgPPU but you can take a look at osgUtil::SceneView
