Types of Projection

The following list explains the different projection types that can be used with the camera. The most common types are the perspective and orthographic projections. In general the CAMERA_TYPE should be the first item in a camera statement. If none is specified, the perspective camera is the default.

Orthographic projection :
This projection uses parallel camera rays to create an image of the scene. The size of the image is determined by the lengths of the right and up vectors.
