| 2707 |  | Taoning added gensdaymtx utility based on gendaymtx, and | 
| 2708 |  | added epw2wea -a option to include required information. | 
| 2709 | + |  | 
| 2710 | + | Fixed bug introduced in Auguest 2022 (5.4 release) in distant | 
| 2711 | + | light source sampling, which caused aiming failures.  (Thanks | 
| 2712 | + | to Mike DiPompeo of LightStanza for reporting the issue.) | 
| 2713 | + |  | 
| 2714 | + | Added rxpict rendering tool based on C++ RpictSimulManager class. | 
| 2715 | + | Multi-processing and spectral output are supported. | 
| 2716 | + |  | 
| 2717 | + | Added crude ability to read and convert spectra to RGB in ximage, | 
| 2718 | + | ra_bmp, and ra_rgbe programs.  Also updated fast tone-mapping | 
| 2719 | + | library to handle spectral HSR inputs at the same time.  HSR | 
| 2720 | + | input handling was added in a similar fashion to pcond and pvalue. | 
| 2721 | + |  | 
| 2722 | + | Wrote rxpiece tool that will render pictures using tiling and | 
| 2723 | + | can handle different output formats and hyperspectral pictures. | 
| 2724 | + | Only runs on a single machine, however -- now NFS locking on | 
| 2725 | + | shared volumes.  Mainly a demonstration tool for RpictSimulManager | 
| 2726 | + | C++ class, but may have its uses. | 
| 2727 | + |  | 
| 2728 | + | Fixed a bug in BSDF sampling of sources pointed out by | 
| 2729 | + | David Geisler-Moroder, which tended to overestimate specular | 
| 2730 | + | contributions for some BSDFs. | 
| 2731 | + |  | 
| 2732 | + | Added handling of hyperspectral pictures to pextrem, though | 
| 2733 | + | results are still reported in RGB. | 
| 2734 | + |  | 
| 2735 | + | Added conversion of hyperspectral pictures to ra_xyze, although | 
| 2736 | + | it is even slower than rcomb for this process.  It is more | 
| 2737 | + | accurate than most of the other tools, at least. | 
| 2738 | + |  | 
| 2739 | + | Added handling of hyperspectral images to normtiff, a little-used | 
| 2740 | + | but handy program for quickly tone-mapping pictures and TIFFs. | 
| 2741 | + |  | 
| 2742 | + | Added conversion of hyperspectral pictures to ra_ps using | 
| 2743 | + | approximate color method. | 
| 2744 | + |  | 
| 2745 | + | Added hyperspectral picture conversion to ra_tiff, with accurate | 
| 2746 | + | color when targeting 16-bit/comp. or LogLuv output, and approximate | 
| 2747 | + | method for 24-bit RGB. |
