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

## Description

```
void
```**swf_polarview**

(double
dist, double
azimuth, double
incidence, double
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.
