| 1824 |  |  | 
| 1825 |  | Removed requirement for pflip -h to be given input file (can pipe from stdin). | 
| 1826 | + |  | 
| 1827 | + | Added "Number of processes" slider to trad "Action" pane to control rad -N | 
| 1828 | + | option for rvu and batch rendering. | 
| 1829 | + |  | 
| 1830 | + | Added -c option to vwrays to repeat pixels for rtcontrib. | 
| 1831 | + |  | 
| 1832 | + | Reworked rtcontrib program and renamed to rcontrib.  New version runs much | 
| 1833 | + | faster, especially on multiprocessor systems, and doesn't require as much | 
| 1834 | + | memory.  No longer calls rtrace; instead does all the work itself. | 
| 1835 | + |  | 
| 1836 | + | Added -d option to genskyvec to produce direct-only (sun no sky) vector. |
