[osg-users] Focus/zoom in a node.

Hi, is there a tutorial where I can see how make the camera focus a particular node, such that the node's bounding box will fit the viewer window? Thank you. ___ osg-users mailing list osg-users@lists.openscenegraph.org

Hi, thank you for replying. Well maybe. Imagine that I load a model so big or so small that with the current camera parameters I can see a thing. I want to adapt the camera automagically so that my current loaded/selected scene/node will fit just nicely on screen. =) Paulo Robert Osfield

HI Paulo, What you need to do is to tell the active CameraManipulator that you've updated the model it should be referring to and then call viewer.home(); viewer.getCameraManipulator()-setNode(myNode); viewer.getCameraManipulator()-computeHomePosition(); viewer.home(); Robert. On Sun, Feb 8,
