Hi all, I have a scene with large terrain where a node starts moving from a given arbitrary location on the terrain. As the starting location of the node is known, i set the camera's target to look as the node's starting position.
My problem is I want to set the initial camera eye to get a nice view of the node before the start of its motion. As it is [b]large terrain[/b] and the node is initially located a position not aligned with any axes of the world cordinate frame, i am [b]finding it difficult to 'guess' what could be the location of the eye of the camera[/b]. To find it, i used nodeTracker manipulator and using the mouse i set the view. I got the nodeTracker's view matrix using: osg::Matrixd nodeTrackerMat = nodetracker->getMatrix() ; Then i used this matrix to get the 'eye' of the camera as: nodeTrackerMat.getLookAt(cam_eye, cam_center, cam_up, lookdistance=1000.); Problem is, when i see the scene by the viewer camera with its 'eye' =cam_eye, 'center' = cam_center 'up' =cam_up, it [b]gives me a view completely different from the view i got from nodeTracker. [/b] . Even with the lookdistance adjustment. Why is this behavior? I cannot use the nodeTracker in scene but need to set the viewer camera's eye position. [b]Any convenient way i can adjust the camera eye position?[/b] This issue is the scene is large one i am not able to think of ny other way i can manually set the camera eye. Can someone give a hint on how to do this? ... Thank you!
