# Line 1446 | Line 1446 | Added meta2bmp program to produce BMP files from metaf
1446  
1447   Added cct_x(t) and cct_y(t) to src/cal/cal/blackbody.cal to interpolate
1448   CIE chromaticities for particular black-body temperatures.
1449 +
1450 + Increased maximum number of input pictures in pcomb and pcompos to 512.
1451 +
1452 + Created rtcontrib program for computing ray contribution coefficients.
1453 + This tool may be used to do standard optical ray tracing or daylight
1454 + coefficient calculations for annual simulations, among other uses.
1455 +
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.)
1476 +
1477 + Changed -t option of rlam to accept strings as well as single characters.
