Re: [osg-users] About how to update the camera
Are you using a default manipulator or are you setting your camera position explicitly? -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of ramy panda Sent: Saturday, October 15, 2011 7:22 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] About how to update the camera Hi, Now I have faced a problem is that when i import a model into my own application, the model is not show at the center of the viewport, only after interacted with the model using translate function i can see the model in the view.

Re: [osg-users] About how to update the camera
Hi Ramy, If it's just the home position of the camera manipuilator that you want to set them use viewer.getCameraManipulator()-setHomePosition(..), or to move the camera to that home position call viewer.home();.

Re: [osg-users] About how to update the camera
Hi, Ramy By default camera view matrix is identity. You should set view matrix on viewer camera to get what you want, or use camera manipulator. Also you can use viewer::run() instead of calling viewer::frame() in loop, this call (along with other things) adds camera manipulator and center view on scene.
