# swf_polarview

(PHP 4 >= 4.0.0)

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.
