# Line 2745 | Line 2745 | 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.
2767 +
2768 + 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.
2771 +
2772 + Simplified synchronization between processes sharing indirect
2773 + irradiance values via an ambient file. Removed file locking
2774 + operations in favor of simpler operation relying on O_APPEND flag.
2775 + Not sure if this will have any affect on shared filesystems, but
2776 + it should reduce overhead for massively parallel machines.
2777 +
2778 + Added rad -N option to rholo run for multiprocessing when
2779 + mkillum and/or mkpmap are involved in octree prep.
