Added i/o for spectral pictures to rmtxop, the first program that can | 
| 2635 | 
  | 
ingest them.  (Only rtrace, rcontrib, and rfluxmtx can render them.) | 
| 2636 | 
  | 
New symbolic rmtxop -c options, such as RGB, XYZ, S (for scotopic) | 
| 2637 | 
< | 
and M (for melanopic) make color conversions simpler. | 
| 2638 | 
< | 
Also added spectral picture support to rcrop and radcompare. |

and M (for melanopic) make color conversions simpler.  Alternatively, | 
| 2638 |

a reference matrix or picture may be given and the color space of | 
| 2639 | 
> | 
that file will be used.  The -C option takes either a symbolic | 
| 2640 | 
> | 
color space or reference file and is "sticky," so it applies to | 
| 2641 | 
> | 
all subsequent input files that do not have their own -c right ahead | 
| 2642 |

of them. | 
| 2643 |

Added spectral picture support to rcrop and radcompare. | 
| 2645 |

 | 
| 2646 |

Added new utility, rcomb, which is something like a combination | 
| 2647 | 
> | 
of rmtxop and pcomb, it works with all the inputs and | 
| 2648 | 
> | 
outputs that rmtxop handles, but allows for general expressions | 
| 2649 | 
> | 
like those in pcomb for putting matrices together, working on | 
| 2650 | 
> | 
an element at a time.  (No resizing of matrices or accessing | 
| 2651 | 
> | 
neighboring elements, as permitted in pcomb.)  It saves memory | 
| 2652 | 
> | 
over rmtxop by operating on a row at a time, so can handle | 
| 2653 | 
> | 
input and output matrices with any number of rows.  It does | 
| 2654 | 
> | 
provide for a single matrix-multiplication operation at the end, | 
| 2655 | 
> | 
which only requires memory for that final matrix. | 
| 2656 |

 | 
| 2657 |

Added support for filtering hyperspectral images to pfilt. | 
| 2658 |

 | 
| 2659 |

Added support for 1- and 3-component float matrix i/o to | 
| 2660 | 
> | 
pcomb to allow for better interoperability. | 
| 2661 |

 | 
| 2662 |

Added support for -co+ option to rtpict, so it can directly | 
| 2663 | 
> | 
produce hyperspectral images. | 
| 2664 | 
> | 
 | 
| 2665 | 
> | 
Added new "specdata" and "specpict" primitives to support | 
| 2666 | 
> | 
interpolated spectral data files and hyperspectral images | 
| 2667 | 
> | 
as patterns. | 
| 2668 | 
> | 
 | 
| 2669 |

Added support for multispectal sampling in rsensor, which will | 
| 2670 | 
> | 
put out as many color channels as specified in any -cs option | 
| 2671 | 
> | 
(default is 3 for RGB). | 
| 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. | 
| 2676 | 
> | 
 | 
| 2677 |

Added handling of spectral images to rcode2bmp script. | 
| 2678 | 
> | 
 | 
| 2679 | 
> | 
Minor change to rcollate to allow explicit byte records to | 
| 2680 | 
> | 
be any specified length without checks against header input. | 
| 2681 | 
> | 
 | 
| 2682 | 
> | 
Added new hemisphere type to rfluxmtx, "h=cie" for CIE sky | 
| 2683 | 
> | 
scanner positions.  These are 145 patches with identical | 
| 2684 | 
> | 
row counts to Tregenza, but starting from a different | 
| 2685 | 
> | 
azimuth and reversing row directions at adjacent altitudes. | 
| 2686 | 
> | 
 | 
| 2687 | 
> | 
Added optimization for long argument lists and arrays in | 
| 2688 | 
> | 
the calcomp routines used for rendering and in rcalc, etc. | 
| 2689 | 
> | 
 | 
| 2690 |

Added error estimate spreading to ambient super-sampling | 
| 2691 | 
> | 
algorithm (-as) to improve performance especially in | 
| 2692 | 
> | 
scenes with sharp cut-offs. | 
| 2693 |

Added -i option to gendaymtx to match -i option of gendaylit. | 
| 2695 | 
> | 
Thanks to Yongqing for initial implementation. | 
| 2696 |

 | 
| 2697 |

Changed rcrop so negative #rows or #cols counts back from end. | 
| 2698 | 
> | 
 | 
| 2699 | 
> | 
Added rcomb -n option for multi-processing of very large matrices. | 
| 2700 | 
> | 
 | 
| 2701 | 
> | 
Made it so rsplit and rlam can handle any number of input files | 
| 2702 | 
> | 
up to active open file descriptor limit. | 
| 2703 |

Taoning Wang added genssky tool for generating spectral sky | 
| 2705 | 
> | 
descriptions. | 
| 2706 |

 | 
| 2707 | 
> | 
Taoning added gensdaymtx utility based on gendaymtx, and | 
| 2708 |

added epw2wea -a option to include required information. |
