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 |
< |
Also added spectral picture support to rcrop and radcompare. |
| 2636 |
> |
New symbolic rmtxop -c options, such as RGB, XYZ, S (for scotopic) |
| 2637 |
> |
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 |

|
| 2644 |

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 |

|
| 2694 |

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. |

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.) |
