void vuangl (phi, theta, radius) D3PLT.C Level 1
 
float phi, theta Angles of viewpoint from center of workbox in degrees. theta is the angle to the z axis. phi is the angle from the x axis in the x-y plane.
float radius Distance of viewpoint from center of workbox in workbox units.
 
This routine allows you to specify a viewpoint in spherical coordinates with origin at the center of the workbox. Do not use with view() or vuabs(). See vuabs() for viewpoint restrictions.
