|
Added rcollate -c option to force operation to continue even if it |
| 2389 |
|
seems unnecessary. Made tool more robust. |
| 2605 |

to create more problems than it solves. |

Version 6.0 (Released July 23, 2025) |
| 2609 |
|
|
| 2610 |
|
Extensive changes to enable spectral rendering, which defaults to "off" |
| 2611 |
|
to maintain backwards-compatibility with previous versions, with the |
| 2672 |
|
|
| 2673 |
|
Added ability of mgf2rad to convert spectral data at least |
| 2674 |
|
for light, glow, plastic, and metal primitive types. Need |
| 2675 |
< |
to use new '-s' option to get new output. |

new WGMDfunc type as well, which is considerably more flexible |

at supporting different spectral components. |
| 2678 |

Added handling of spectral images to rcode2bmp script. |
| 2679 |
> |
Added handling of spectral pictures (HSR) to rcode2bmp script. |
| 2680 |
|
|
| 2681 |
|
Minor change to rcollate to allow explicit byte records to |
| 2682 |
|
be any specified length without checks against header input. |
| 2718 |
|
|
| 2719 |
|
Wrote rxpiece tool that will render pictures using tiling and |
| 2720 |
|
can handle different output formats and hyperspectral pictures. |
| 2721 |

Only runs on a single machine, however -- now NFS locking on |

shared volumes. Mainly a demonstration tool for RpictSimulManager |

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

C++ class, but later added to standard Rmakefile targets. |
| 2724 |
|
|
| 2725 |
|
Fixed a bug in BSDF sampling of sources pointed out by |
| 2726 |
|
David Geisler-Moroder, which tended to overestimate specular |
| 2742 |
|
Added accurate conversion of hyperspectral pictures to ra_xyze. |
| 2743 |
|
|
| 2744 |
|
Added hyperspectral picture conversion to ra_tiff, with accurate |
| 2745 |
< |
color when targeting 16-bit/comp., LogLuv, and float utput, |
| 2745 |
> |
color when targeting 16-bit/comp., LogLuv, and float output, |
| 2746 |
|
and the approximate method for 24-bit RGB. |
| 2747 |
|
|
| 2748 |
|
Taoning added genssky -L option to specify global and diffuse |
| 2749 |
|
illuminance values for output calibration. |
| 2750 |
+ |
|
| 2751 |
+ |
Created C++ class for rcontrib and example tool rxcontrib, which |
| 2752 |
+ |
is an optional compile in the src/rt directory. The output |
| 2753 |
+ |
model is more general in some respects and the operations more |
| 2754 |
+ |
efficient, but standard output is not supported, nor is ASCII |
| 2755 |
+ |
results data. |
| 2756 |
+ |
|
| 2757 |
+ |
Added strnstr.c compatibility module in ray/src/common, since |
| 2758 |
+ |
it isn't present on Linux derivatives. |
| 2759 |
+ |
|
| 2760 |
+ |
Added WGMDfunc material type with programmable roughness and |
| 2761 |
+ |
separate modifier paths for the different components. |
| 2762 |
+ |
|
| 2763 |
+ |
Added gensurf -i option at the request of Peter Apian-Bennewitz |
| 2764 |
+ |
to reverse surface normals, mostly for data input, when it is |
| 2765 |
+ |
a bit more difficult to adjust. |
| 2766 |
+ |
|
| 2767 |
+ |
Added rad -N option to rholo call for multiprocessing when |
| 2768 |
+ |
mkillum and/or mkpmap are involved in octree prep. |
| 2769 |
+ |
|
| 2770 |
+ |
Added ability of gendaymtx to read EPW as well as WEA files. |
| 2771 |
+ |
When EPW input is provided, the 3-hour average dew point is |
| 2772 |
+ |
used to compute a more accurate precipitable water content |
| 2773 |
+ |
value. It currently does not use these data directly from |
| 2774 |
+ |
the EPW input, relying instead on a dew-point-to-W calculation. |
| 2775 |
+ |
This follows the request and recommendations of David G-M. |
| 2776 |
+ |
|
| 2777 |
+ |
Removed limitation in rfluxmtx, which was disallowing distant |
| 2778 |
+ |
and local receivers. Found this to be a perfectly valid approach |
| 2779 |
+ |
for some annual daylighting scenarios. |
| 2780 |
+ |
|
| 2781 |
+ |
Wrote new pvsum tool to handle cases dctimestep can't, like |
| 2782 |
+ |
spectral input pictures. It also adds a -N option for multi- |
| 2783 |
+ |
processing on Unix machines, which utilizes memory-mapped |
| 2784 |
+ |
inputs for efficient i/o sharing. |
| 2785 |
+ |
|
| 2786 |
+ |
Made it so genBSDF can use spectral rendering for a |
| 2787 |
+ |
more accurate photometric result. |
| 2788 |
+ |
|
| 2789 |
+ |
Changed default matrix representation to float rather than |
| 2790 |
+ |
double, which uses less RAM and supports faster operations |
| 2791 |
+ |
in general. Build with compiler flag: |
| 2792 |
+ |
-DDTnativeDTrmx_native=DTdouble |
| 2793 |
+ |
to get back higher precision representation. |
| 2794 |
+ |
|
| 2795 |
+ |
Taoning Wang updated genssky and gensdaymtx to provide illuminance |
| 2796 |
+ |
calibration and accept EPW files directly as input. |
| 2797 |
+ |
|
| 2798 |
+ |
Added -e expr and -f file.cal options to all rendering tools, not |
| 2799 |
+ |
just rcontrib/rxcontrib. Feature request from Peter A-B. |
| 2800 |
+ |
|
| 2801 |
+ |
Fixed slight bias in indirect calculation caused by ambient |
| 2802 |
+ |
collision detection, pointed out by Jon Sargent. New code |
| 2803 |
+ |
keeps track of rejected samples and sells them back to |
| 2804 |
+ |
later calls to get something closer to a true Poisson |
| 2805 |
+ |
sampling method. |
| 2806 |
+ |
|
| 2807 |
+ |
Altered rvu "origin" command to take shift amounts forward, |
| 2808 |
+ |
right, and up rather than taking an explicit origin, which |
| 2809 |
+ |
can be done easily enough with the "view" command. Peter A-B |
| 2810 |
+ |
requested (sort of). |
| 2811 |
+ |
|
| 2812 |
+ |
Added genglaze tool created by Taoning Wang to generate |
| 2813 |
+ |
spectral glazing materials based on CGDB data and models. |
| 2814 |
+ |
|
| 2815 |
+ |
Fixed bug that caused inf and nan errors with -cw setting |
| 2816 |
+ |
where longer wavelength was substantially less than limits |
| 2817 |
+ |
of specified spectra. |
| 2818 |
+ |
|
| 2819 |
+ |
Created bsdfpeaks utility to identify and report full-width, |
| 2820 |
+ |
half-maximum sizes of peaks in SIR and XML inputs. |
| 2821 |
+ |
|
| 2822 |
+ |
Changed default super-sampling in bsdf2ttree from 256 to 64, |
| 2823 |
+ |
since there doesn't seem to be much benefit to the higher |
| 2824 |
+ |
sampling rate for most BSDFs. |
| 2825 |
+ |
|
| 2826 |
+ |
Fixed problem with "mirror" primitive, which was not permitting |
| 2827 |
+ |
indirect rays to transmit through alternate material type. |
| 2828 |
+ |
Thanks to Jon Sargent for finding problem and help resolving it. |
| 2829 |
+ |
|
| 2830 |
+ |
Added experimental C++ based rxpiece tool to default installation |
| 2831 |
+ |
in makeall/Rmakefile. |
| 2832 |
+ |
|
| 2833 |
+ |
Added rcomb -mt option to transpose concatenation matrix. |
| 2834 |
+ |
|
| 2835 |
+ |
==================== |
| 2836 |
+ |
Version 6.1 (Released July 24, 2025) |
| 2837 |
+ |
|
| 2838 |
+ |
Fixed array limit bug in EPW file loader. |
| 2839 |
+ |
|
| 2840 |
+ |
Fixed bug in rcomb, rmtxop -c and -C option not accepting file paths |
| 2841 |
+ |
starting with '.' |
| 2842 |
+ |
|
| 2843 |
+ |
Fixed ordering of spectral data in gensdaymtx output. |
| 2844 |
+ |
|
| 2845 |
+ |
Fixed crash in new Poisson sampling routines for large settings of -ad. |
| 2846 |
+ |
|
| 2847 |
+ |
Fixed reversal of direct and diffuse values in EPW files. (Thanks to |
| 2848 |
+ |
Taoning Wang for spotting the error.) |
| 2849 |
+ |
|
| 2850 |
+ |
Fixed issue with zero radiation values in gensdaymtx (TW). |
| 2851 |
+ |
|
| 2852 |
+ |
(The above fixes were released as official patch 6.0.1) |
| 2853 |
+ |
|
| 2854 |
+ |
Fixed issues with rtpict running under Windows. Thanks to Mehlika |
| 2855 |
+ |
Inanici for help finding problems and testing. |
