| 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. | 
| 1837 | + |  |

| 1839 | + | from Nicolas Boneel. | 
| 1840 | + |  | 
| 1841 | + | Added Ruby rewrite of objview.csh by Rob Guglielmetti. | 
| 1842 | + |  | 
| 1843 | + | Fixed bug in reciprocity for tensor tree BTDF representations.  Thanks | 
| 1844 | + | to Andy McNeil for identifying the problem. | 
| 1845 | + |  | 
| 1846 | + | Added MNAME and ZNAME variables to ranimove for debugging & testing. | 
| 1847 | + |  | 
| 1848 | + | Created pmblur2 command to take motion and depth buffers from ranimove | 
| 1849 | + | to compute a better motion blur. |
