Modified -c option to rtcontrib so it can take a number of input | 
| 1665 | 
  | 
rays to average over, rather than only produce a single accumulated | 
| 1666 | 
  | 
record (which can now be done with -c 0). |

===================== | 
| 1669 | 
+ | 
Version 4.0 | 
| 1670 | 
+ | 
 | 
| 1671 | 
+ | 
Added -n option to rvu to provide parallel rendering. | 
| 1672 |

****** COMPATIBILITY CHANGE ******** | 
| 1674 | 
+ | 
Changed ".pic" extension to ".hdr" in all sources and documentation | 
| 1675 | 
+ | 
to improve interoperability with other software, since this has become | 
| 1676 | 
+ | 
the de facto extension for Radiance RGBE and XYZE pictures.  Since file | 
| 1677 | 
+ | 
extensions were never more than a convention in Radiance, this does not | 
| 1678 | 
+ | 
affect operation, but may require the update of scripts, etc. written | 
| 1679 | 
+ | 
by others that assume the ".pic" suffix for Radiance output. | 
| 1680 | 
+ | 
 | 
| 1681 | 
+ | 
Added -N option to objview to support multiprocessing. | 
| 1682 | 
+ | 
 | 
| 1683 | 
+ | 
Improved sampling of circular sources (source, sphere, ring types) with | 
| 1684 | 
+ | 
quite a bit of help from David Geisler-Moroder. | 
| 1685 | 
+ | 
 | 
| 1686 | 
+ | 
Added "rpict" and "rvu" variables to rad, and made these as well as | 
| 1687 | 
+ | 
the "oconv", "mkillum" and "pfilt" variables accept an alternate | 
| 1688 | 
+ | 
command path in each case.  Change suggested by Lars Grobe based | 
| 1689 | 
+ | 
on similar Radzilla (radz) facility by Carsten Bauer. | 
| 1690 | 
+ | 
 | 
| 1691 | 
+ | 
Fixed rad -v N specification to use actual view name if one. |
