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.) |

|
| 2714 |

Added rxpict rendering tool based on C++ RpictSimulManager class. |
| 2715 |
+ |
Multi-processing and spectral output are supported. |
| 2716 |
+ |
|
| 2717 |
+ |
Wrote rxpiece tool that will render pictures using tiling and |
| 2718 |
+ |
can handle different output formats and hyperspectral pictures. |
| 2719 |
+ |
Only runs on a single machine, however -- now NFS locking on |
| 2720 |
+ |
shared volumes. Mainly a demonstration tool for RpictSimulManager |
| 2721 |
+ |
C++ class, but may have its uses. |
| 2722 |
+ |
|
| 2723 |
+ |
Fixed a bug in BSDF sampling of sources pointed out by |
| 2724 |
+ |
David Geisler-Moroder, which tended to overestimate specular |
| 2725 |
+ |
contributions for some BSDFs. |
| 2726 |
+ |
|
| 2727 |
+ |
Added crude ability to read and convert spectra to RGB in ximage, |
| 2728 |
+ |
ra_bmp, ra_ps, and ra_rgbe programs. Also updated fast tone-mapping |
| 2729 |
+ |
library to handle spectral HSR inputs at the same time. HSR |
| 2730 |
+ |
input handling was added in a similar fashion to pcond and pvalue |
| 2731 |
+ |
for convenience. |
| 2732 |
+ |
|
| 2733 |
+ |
Added handling of hyperspectral images to normtiff, a handy program |
| 2734 |
+ |
for quickly tone-mapping Radiance RGBE, XYZE, and now hyperspectral |
| 2735 |
+ |
pictures, as well as IEEE float or LogLuv TIFFs. |
| 2736 |
+ |
|
| 2737 |
+ |
Added handling of hyperspectral pictures to pextrem, though |
| 2738 |
+ |
results are still reported in RGB. |
| 2739 |
+ |
|
| 2740 |
+ |
Added accurate conversion of hyperspectral pictures to ra_xyze. |
| 2741 |
+ |
|
| 2742 |
+ |
Added hyperspectral picture conversion to ra_tiff, with accurate |
| 2743 |
+ |
color when targeting 16-bit/comp., LogLuv, and float utput, |
| 2744 |
+ |
and the approximate method for 24-bit RGB. |
