NAME

DoParallel − Create a parallel studio attribute object for cameras

SYNOPSIS

C:

DtObject DoParallel(window_size, hither, yon)
DtReal window_size, hither, yon;

Fortran:

INTEGER∗4 DOPAR(WWSIZE, HITHER, YON)
REAL∗8 WWSIZE, HITHER, YON

DESCRIPTION

DoParallel creates a parallel studio attribute object for cameras.  The parameter window_size specifies the square size of the field of view that is centered at the origin and parallel to the XY-plane.  The parameters hither and yon specify the location of the front and the back clipping planes in camera coordinates.  Note that, for parallel cameras, these planes may actually be behind the camera (that is, positive numbers). 

ERRORS

DoParallel will fail if hither is less than or equal to yon

[WARNING - value out of range]
