NAME

projray - project rays to a X-Y plane

DESCRIPTION

projray projects rays to a X-Y plane with a given Z coordinate value. It reads and writes bpipe formatted ray streams.

PARAMETERS

projray uses an IRAF-compatible parameter interface.

The following parameters are available:

input file

Input ray stream. If the filename is the string stdin, it reads the UNIX standard input stream. It accepts rays in bpipe format.

output file

Output ray stream. If the filename is the string stdout, it writes to the UNIX standard output stream. It writes rays in bpipe format.

z float

The Z position of the plane to which the rays will be projected.

debug list

A list of debug flags. The following are defined:

save-history

If specified, the new position is prepended the list of positions stored in the ray packet, rather than replacing the previous position.
