===================== | 
| 1669 | 
  | 
Version 4.0 | 
| 1670 | 
+ | 
 | 
| 1671 | 
+ | 
Added -n option to rvu to provide parallel rendering. | 
| 1672 | 
+ | 
 | 
| 1673 | 
+ | 
****** 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. |
