# Line 2678 | Line 2678 | 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 +
2704 + 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.
2709 +
2710 + 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.)
2713 +
2714 + Added rxpict rendering tool based on C++ RpictSimulManager class.
2715 + Multi-processing and spectral output are supported.
2716 +
2717 + Added crude ability to read and convert spectra to RGB in ximage,
2718 + ra_bmp, and ra_rgbe programs.  Also updated fast tone-mapping
2719 + library to handle spectral HSR inputs at the same time.  HSR
2720 + input handling was added in a similar fashion to pcond and pvalue.
2721 +
2722 + Wrote rxpiece tool that will render pictures using tiling and
2723 + can handle different output formats and hyperspectral pictures.
2724 + Only runs on a single machine, however -- now NFS locking on
2725 + shared volumes.  Mainly a demonstration tool for RpictSimulManager
2726 + C++ class, but may have its uses.
2727 +
2728 + Fixed a bug in BSDF sampling of sources pointed out by
2729 + David Geisler-Moroder, which tended to overestimate specular
2730 + contributions for some BSDFs.
2731 +
2732 + Added handling of hyperspectral pictures to pextrem, though
2733 + results are still reported in RGB.
2734 +
2735 + Added conversion of hyperspectral pictures to ra_xyze, although
2736 + it is even slower than rcomb for this process.  It is more
2737 + accurate than most of the other tools, at least.
2738 +
2739 + Added handling of hyperspectral images to normtiff, a little-used
2740 + but handy program for quickly tone-mapping pictures and TIFFs.
2741 +
2742 + Added conversion of hyperspectral pictures to ra_ps using
2743 + approximate color method.
2744 +
2745 + Added hyperspectral picture conversion to ra_tiff, with accurate
2746 + color when targeting 16-bit/comp. or LogLuv output, and approximate
2747 + method for 24-bit RGB.
