Detailed Description
A perspective camera defines a perspective projection from a viewpoint. The viewing volume for a perspective camera is a truncated right pyramid.
By default, the camera is located at (0,0,1) and looks along the negative z-axis; the position and orientation fields can be used to change these values. The heightAngle field defines the total vertical angle of the viewing volume; this and the aspectRatio field determine the horizontal angle.

If the useAspectRatio field is not 0.0 (the default), the camera uses that ratio instead of the one it has.
