Hi Roman, Just set up the view matrix using osg::Matrix calls. Please note, HPR can be done in many different ways depending on what convention you use, so the OSG doesn't try to solve this can of worms, rather it gives you all the tools to do what convention you want to adopt.
For instance the Matrix::rotate(..) method has one variation that takes three rotation angles and three axis about which to rotate, you can use this to do HPR with any convention you wish. You can write you own convinience methods for doing this. Once you have the matrix just pass this to the camera via setViewMatrix. Robert. On 5/16/07, Roman Grigoriev <[EMAIL PROTECTED]> wrote:
Hi Robert! I still don't understand how to do this simple way so I need thing like this camera-SetPositionAndHPR(pos,HPR); could you plese write here simple code how to move camera manually to desired position and rotate it to HPR angles Thanx in advance Roman ----- Original Message ----- From: "Robert Osfield" <[EMAIL PROTECTED]> To: "osg users" <[email protected]> Sent: Wednesday, May 16, 2007 3:27 PM Subject: Re: [osg-users] Nub Q: how to move camera > Hi Roman, > > There are lots of ways of controlling the camera, via one of the range > of CameraMaipulators that you'll find in osgGA, or a custom > manipulator likes these, or simple set your views master Camera's > View and Projection matrices yourself. > > For tracking a node you might want to try the > osgGA::NodeTrackerManipulator.
