Detailed Description

mitkCamera - a camera in 3D scene

mitkCamera is a camera in 3D scene. The only way you can access it is to get a pointer to it by using the member function GetCamera() of mitkScene. Then you can control it through its interface, and the change will affect the image rendered in the scene.
