projray - project rays to a X-Y plane
projray projects rays to a X-Y plane with a given Z coordinate value. It reads and writes bpipe formatted ray streams.
projray uses an IRAF-compatible parameter interface.
The following parameters are available:
Input ray stream. If the filename is the string stdin, it reads the UNIX standard input stream. It accepts rays in bpipe format.
Output ray stream. If the filename is the string stdout, it writes to the UNIX standard output stream. It writes rays in bpipe format.
The Z position of the plane to which the rays will be projected.
A list of debug flags. The following are defined:
If specified, the new position is prepended the list of positions stored in the ray packet, rather than replacing the previous position.
