swf_polarview --
Define the viewer's position with polar coordinates

## 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.
