# Line 2716 | Line 2716 | Multi-processing and spectral output are supported.
2716  
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.

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.
2755 > Added strnstr.c compatibility module in ray/src/common, since
2756 > it isn't present on Linux derivatives.
2757 >
2758 > Added WGMDfunc material type with programmable roughness and
2759 > separate modifier paths for the different components.
2760 >
2761 > Added gensurf -i option at the request of Peter Apian-Bennewitz
2762 > to reverse surface normals, mostly for data input, when it is
2763 > a bit more difficult to adjust.
2764 >
2765 > Added rad -N option to rholo call for multiprocessing when
2766 > mkillum and/or mkpmap are involved in octree prep.
2767 >
2768 > Added ability of gendaymtx to read EPW as well as WEA files.
2769 > When EPW input is provided, the 3-hour average dew point is
2770 > used to compute a more accurate precipitable water content
2771 > value.  It currently does not use these data directly from
2772 > the EPW input, relying instead on a dew-point-to-W calculation.
2773 > This follows the request and recommendations of David G-M.
2774 >
2775 > Removed limitation in rfluxmtx, which was disallowing distant
2776 > and local receivers. Found this to be a perfectly valid approach
2777 > for some annual daylighting scenarios.
2778 >
2779 > Wrote new pvsum tool to handle cases dctimestep can't, like
2780 > spectral input pictures.  It also adds a -N option for multi-
2781 > processing on Unix machines, which utilizes memory-mapped
2782 > inputs for efficient i/o sharing.
