Description
void 
swf_polarview ( float dist, float azimuth, float incidence, float twist )
     The swf_polarview() function defines the
     viewer's position in polar coordinates.  The
     dist parameter gives the distance between
     the viewpoint to the world space origin.  The
     azimuth parameter defines the azimuthal
     angle in the x,y coordinate plane, measured in distance from the
     y axis.  The incidence parameter defines
     the angle of incidence in the y,z plane, measured in distance
     from the z axis.  The incidence angle is defined as the angle of
     the viewport relative to the z axis.  Finally the
     twist specifies the amount that the
     viewpoint is to be rotated about the line of sight using the
     right hand rule.
