| 1709 | > | Created genskyvec  utility to sample a particular sky and | 
| 1710 |  | evaluate average radiance over the standard Tregenza sky patches. | 
| 1711 |  |  | 
| 1712 |  | Created dctimestep program to compute a set of sensor values or | 
| 1715 |  |  | 
| 1716 |  | Created src/rt/rayfifo.c for first-in/first-out handling of | 
| 1717 |  | multiprocessing by raypcalls.c. | 
| 1718 | + |  | 
| 1719 | + | Added -n option to rtrace for executing on multiple cores | 
| 1720 | + | using new rayfifo calls. |

| 1727 | + | home directory. | 
| 1728 | + |  | 
| 1729 | + | Changed standard transmission function normalization back to what | 
| 1730 | + | it was in version 3.5, following recommendation of David Geisler-Moroder, | 
| 1731 | + | who pointed out that the revised BTDF increased too much at grazing. |
