Setting Up the Camera
Setting up the virtual view camera is the last step in preparing to render an image. For simple setups, or for moving around your 3D design generally, you can use the Walk view control or from the view control bar in the view border. For more precise setups, however, the Define Camera tool provides a simple system to set up a view for rendering. As well as the camera positioning tools, it includes options for changing the view projection.
Using similar terminology to that used in the movie world, the Define Camera tool settings let you Orient, Pan, Roll, or Dolly the camera. It is easy to imagine a real camera and its physical movement when using this tool. For example, with reference point set to eye, when you want to see the area just to the left of the view extents, you Pan Horizontally to the left, and the objects move to the right as you would expect.
