# Line 1456 | Line 1456 | coefficient calculations for annual simulations, among
1456   Added tilde ('~') output option as part of the -o* specification of
1457   rtrace.  This permits ray trees to be parsed more easily in binary
1458   output mode, as needed by rtcontrib.
1459 +
1460 + Implemented Russian roulette ray termination with -lr <= 0.
1461 + Made -lr -10 the default in rtcontrib.
1462 +
1463 + Made rtcontrib -f option search RAYPATH directories.
1464 +
1465 + Made it so -o option of rtcontrib can pipe -o output to a command.
1466 +
1467 + Added -if and -of options to total for binary i/o (following rcalc mold).
1468 +
1469 + Switched default options in rtrace to use Russian roulette.  (Rpict and rvu
1470 + still use biased ray termination.)
1471 +
1472 + Added rtcontrib -r option to recover partial output.
1473 +
1474 + Added -R rendering option for pure Monte Carlo sampling.
1475 + (Got rid of -DMC compile option, whicht his makes superfluous.)
