mxwldmn - filter rays based upon their weight
mxwldmn uses the standard parameter interface
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 first seed for the random number generator.
The second seed for the random number generator.
The block in the random number sequence at which to start using random numbers. (There are 1,048,576 blocks of 1,073,741,824 random numbers each).

mxwldmn reads a ray stream in bpipe format and discards rays based upon their weight. It generates a uniformly distributed random number (using ranlib's genunf function) between 0 and 1, and discards the ray if it's weight is less than the random number. The weights of rays which are not discarded are set to unity; their polarization information is discarded as well.
It writes out a bpipe formatted ray stream.
