Added new hemisphere type to rfluxmtx, "h=cie" for CIE sky |

scanner positions. These are 145 patches with identical |

Fixed bug introduced in Auguest 2022 (5.4 release) in distant |

Added rxpict rendering tool based on C++ RpictSimulManager class. |

Multi-processing and spectral output are supported. |

Wrote rxpiece tool that will render pictures using tiling and |

can handle different output formats and hyperspectral pictures. |
| 2719 |

Only runs on a single machine, however -- no NFS locking on |
| 2720 |

shared volumes. Mainly a demonstration tool for RpictSimulManager |
| 2721 |

C++ class, but may have its uses. |

Fixed a bug in BSDF sampling of sources pointed out by |

David Geisler-Moroder, which tended to overestimate specular |

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 |

input handling was added in a similar fashion to pcond and pvalue |

Added handling of hyperspectral images to normtiff, a handy program |

for quickly tone-mapping Radiance RGBE, XYZE, and now hyperspectral |

pictures, as well as IEEE float or LogLuv TIFFs. |

results are still reported in RGB. |

Added accurate conversion of hyperspectral pictures to ra_xyze. |

Added hyperspectral picture conversion to ra_tiff, with accurate |

color when targeting 16-bit/comp., LogLuv, and float utput, |

Created C++ class for rcontrib and example tool rxcontrib, which |
| 2750 |
> |
is an optional compile in the src/rt directory. The output |
| 2751 |

model is more general in some respects and the operations more |
| 2752 |

efficient, but standard output is not supported, nor is ASCII |
| 2753 |

results data. |
| 2754 |

Added strnstr.c compatibility module in ray/src/common, since |
| 2756 |

it isn't present on Linux derivatives. |
| 2757 |

Added WGMDfunc material type with programmable roughness and |
| 2759 |

separate modifier paths for the different components. |

Added gensurf -i option at the request of Peter Apian-Bennewitz |
| 2762 |

to reverse surface normals, mostly for data input, when it is |
| 2763 |

a bit more difficult to adjust. |

Added rad -N option to rholo call for multiprocessing when |
| 2766 |

mkillum and/or mkpmap are involved in octree prep. |

|
| 2768 |

Added ability of gendaymtx to read EPW as well as WEA files. |
| 2769 |
> |
When EPW input is provided, the 3-hour average dew point is |
| 2770 |
> |
used to compute a more accurate precipitable water content |
| 2771 |
> |
value. It currently does not use these data directly from |
| 2772 |
> |
the EPW input, relying instead on a dew-point-to-W calculation. |
| 2773 |

This follows the request and recommendations of David G-M. |

Removed limitation in rfluxmtx, which was disallowing distant |
| 2776 |

for some annual daylighting scenarios. |

Wrote new pvsum tool to handle cases dctimestep can't, like |
| 2780 |

spectral input pictures. It also adds a -N option for multi- |

processing on Unix machines, which utilizes memory-mapped |
| 2782 |

inputs for efficient i/o sharing. |
| 2783 |

Made it so genBSDF can use spectral rendering for a |
| 2785 |

more accurate photometric result. |

|
| 2787 |

Changed default matrix representation to float rather than |
| 2788 |
> |
double, which uses less RAM and supports faster operations |
| 2789 |

in general. Build with compiler flag: |
| 2790 |

-DDTnativeDTrmx_native=DTdouble |
| 2791 |

to get back higher precision representation. |
