| 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.) |
