If the polarview subroutine is the first transformation subroutine called after projection matrix is set up and the matrix stack is initialized, it sets up such a mapping. The eye is located a distance, given in the distance parameter, from the world space origin. The incidence and azimuth are measured with respect to the world coordinate system. The polarview subroutine can also be used as a modeling transformation. Whether it behaves as a viewing transformation or a modeling transformation depends entirely on the order in which it is called with respect to the drawing subroutines.
Parameters distance Specifies the distance from the eye to the world space origin.
The angle must be specified as an integer, in tenths of a degree. The angle must be specified as an integer, in tenths of a degree. The angle must be specified as an integer, in tenths of a degree.
