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 back clipping planes in camera coordinates.  Because the camera’s location in its own relative coordinate system is always at (0.0, 0.0, 0.0) looking down the negative Z axis, both hither and yon will typically be negative. 

ERRORS

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

[WARNING - value out of range]
