# Line 2683 | Line 2683 | Added new hemisphere type to rfluxmtx, "h=cie" for CIE
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.
