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.
