swf_polarview — Set viewport in polar coordinates
void swf_polarview(distance, azimuth, incidence, twist);
string distance: Viewport
string azimuth: Azimuth
string incidence: Angle of
string twist: Rotation of
Defines the viewer's position in polar coordinates. distance selects the distance from
the viewpoint to the world space origin. azimuth defines the azimuthal angle in
the x-y plane, measured from the y axis. incidence specifies the angle of
incidence in the y-z plane, measured from the z axis. The
incidence angle is the angle of the viewport relative to
the z axis. twist defines the
amount that the viewpoint is to be rotated around the
line of sight using the right-hand rule.
