><P
> The <B
CLASS="function"
>swf_polarview()</B
> function defines the
viewer's position in polar coordinates. The
<TT
CLASS="parameter"
><I
>dist</I
></TT
> parameter gives the distance between
the viewpoint to the world space origin. The
<TT
CLASS="parameter"
><I
>azimuth</I
></TT
> parameter defines the azimuthal
angle in the x,y coordinate plane, measured in distance from the
y axis. The <TT
CLASS="parameter"
><I
>incidence</I
></TT
> 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
<TT
CLASS="parameter"
><I
>twist</I
></TT
> specifies the amount that the
viewpoint is to be rotated about the line of sight using the
right hand rule.
