# Line 2714 | Line 2714 | to Mike DiPompeo of LightStanza for reporting the issu
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
2717   Wrote rxpiece tool that will render pictures using tiling and
2718   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.
2722 +
2723 + Fixed a bug in BSDF sampling of sources pointed out by
2724 + David Geisler-Moroder, which tended to overestimate specular
2725 + contributions for some BSDFs.
2726 +
2727 + 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.
2732 +
2733 + 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 +
2737 + Added handling of hyperspectral pictures to pextrem, though
2738 + results are still reported in RGB.
2739 +
2740 + Added accurate conversion of hyperspectral pictures to ra_xyze.
2741 +
2742 + Added hyperspectral picture conversion to ra_tiff, with accurate
2743 + color when targeting 16-bit/comp., LogLuv, and float utput,
2744 + and the approximate method for 24-bit RGB.
2745 +
2746 + Taoning added genssky -L option to specify global and diffuse
2747 + illuminance values for output calibration.
2748 +
2749 + 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.
2754 +
2755 + 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.
2761 +
2762 + Added strnstr.c compatibility module in ray/src/common, since
2763 + it isn't present on Linux-derivatives.
2764 +
2765 + Added WGMDfunc material type with programmable roughness and
2766 + separate modifier paths for the different components.
