polarview(3G) polarview(3G)
NAME
polarview - defines the viewer's position in polar
coordinates
SPECIFICATION
C polarview(dist, azim, inc, twist)
Coord dist;
Angle azim, inc, twist;
FORTRAN subroutine polarv(dist, azim, inc, twist)
real dist
integer*4 azim, inc, twist
DESCRIPTION
polarview defines the viewer's position in polar
coordinates. 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 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.
