The POV-Ray camera has ten different models, each of which uses a different projection method to project the scene onto your screen. Regardless of the projection type all cameras use the location, right, up, direction, and keywords to determine the location and orientation of the camera. The type keywords and these four vectors fully define the camera. All other camera modifiers adjust how the camera does its job. The meaning of these vectors and other modifiers differ with the projection type used. A more detailed explanation of the camera types follows later. In the sub-sections which follows, we explain how to place and orient the camera by the use of these four vectors and the sky and look_at modifiers. You may wish to refer to the illustration of the perspective camera below as you read about these vectors.
