NAME

polarview - define the viewer’s position in polar coordinates

SYNOPSIS

C
polarview(dist, azim, inc, twist)
Coord dist;
Angle azim, inc, twist;

FORTRAN
subroutine polarv(dist, azim, inc, twist)
real dist
integer∗2 azim, inc, twist

Pascal
procedure polarview(dist: Coord; azim, inc, twist: Angle);

DESCRIPTION

Polarview defines the viewer’s position in polar coordinates.  The first three parameters, dist, azim, and inc, define a viewpoint.  Dist is the distance from the viewpoint to the world space origin.  Azim is the angle in the x-y plane, measured from the y axis.  Inc is the angle in y-z plane, measured from the z axis.  The line of sight extends from the viewpoint through the world space origin.  Twist rotates the viewpoint around the line of sight using the right-hand rule.  All angles are specified in tenths of degrees and are integers.
