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 |

Added spectral picture support to rcrop and radcompare. |

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 |

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 |

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. |

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. |

Taoning added gensdaymtx utility based on gendaymtx, and |

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

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 -- now 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 |

contributions for some BSDFs. |

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 |
| 2730 |

input handling was added in a similar fashion to pcond and pvalue |
| 2731 |

for convenience. |

Added handling of hyperspectral images to normtiff, a handy program |
| 2734 |

for quickly tone-mapping Radiance RGBE, XYZE, and now hyperspectral |
| 2735 |

pictures, as well as IEEE float or LogLuv TIFFs. |
| 2736 |

Added handling of hyperspectral pictures to pextrem, though |

results are still reported in RGB. |
| 2739 |

|
| 2740 |

Added accurate conversion of hyperspectral pictures to ra_xyze. |

Added hyperspectral picture conversion to ra_tiff, with accurate |
| 2743 |

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

and the approximate method for 24-bit RGB. |

Taoning added genssky -L option to specify global and diffuse |

illuminance values for output calibration. |

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. |

Added experimental source-skipping method to rpict for scenes |
| 2756 |
> |
with large number of light sources. Currently works with |
| 2757 |
> |
rcontrib and separate srcsamp image-processing tool. Controlling |
| 2758 |

rpict options are -dS for skip bitmap specification and -dC |
| 2759 |

for correction coefficient image. Compile using -DSSKIPOPT |
| 2760 |

to include this option. |

Added strnstr.c compatibility module in ray/src/common, since |
| 2763 |

it isn't present on Linux-derivatives. |

Added WGMDfunc material type with programmable roughness and |
| 2766 |

separate modifier paths for the different components. |

Added gensurf -i option at the request of Peter Apian-Bennewitz |
| 2769 |

to reverse surface normals, mostly for data input when it is |
| 2770 |

a bit more difficult to adjust. |
