Insight3D's 3D control automatically provides rotating and zooming in a 3D scene using the mouse. The camera object provides full control over the viewer's position and orientation. When the camera is initialized with DGL's point or vector objects, the camera automatically moves when the point or vector change. The camera also provides higher level methods, such as the ability to view an entire central body or zoom to a rectangular extent on the globe. The camera is used to set view parameters like the field of view, near plane distance, and far plane distance. The camera provides functionality for taking snapshots of the 3D window as well as recording videos.
