| 2388 | 
  | 
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) |

| 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. |

to use new '-s' option to get new output.  Added support for |

new WGMDfunc type as well, which is considerably more flexible | 
| 2677 |

at supporting different spectral components. |

Added handling of spectral images to rcode2bmp script. |

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. | 
| 2720 | 
  | 
can handle different output formats and hyperspectral pictures. | 
| 2721 | 
  | 
Only runs on a single machine, however -- no NFS locking on | 
| 2722 | 
  | 
shared volumes.  Mainly a demonstration tool for RpictSimulManager | 
| 2723 | 
< | 
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 | 
| 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. |
