The output +model is more general in some respects and the operations more +efficient, but standard output is not supported, nor is ASCII +results data. + +Added strnstr.c compatibility module in ray/src/common, since +it isn't present on Linux derivatives. + +Added WGMDfunc material type with programmable roughness and +separate modifier paths for the different components. + +Added gensurf -i option at the request of Peter Apian-Bennewitz +to reverse surface normals, mostly for data input, when it is +a bit more difficult to adjust. + +Added rad -N option to rholo call for multiprocessing when +mkillum and/or mkpmap are involved in octree prep. + +Added ability of gendaymtx to read EPW as well as WEA files. +When EPW input is provided, the 3-hour average dew point is +used to compute a more accurate precipitable water content +value. It currently does not use these data directly from +the EPW input, relying instead on a dew-point-to-W calculation. +This follows the request and recommendations of David G-M. + +Removed limitation in rfluxmtx, which was disallowing distant +and local receivers. Found this to be a perfectly valid approach +for some annual daylighting scenarios. + +Wrote new pvsum tool to handle cases dctimestep can't, like +spectral input pictures. It also adds a -N option for multi- +processing on Unix machines, which utilizes memory-mapped +inputs for efficient i/o sharing. + +Made it so genBSDF can use spectral rendering for a +more accurate photometric result. + +Changed default matrix representation to float rather than +double, which uses less RAM and supports faster operations +in general. Build with compiler flag: + -DDTnativeDTrmx_native=DTdouble +to get back higher precision representation. + +Taoning Wang updated genssky and gensdaymtx to provide illuminance +calibration and accept EPW files directly as input. + +Added -e expr and -f file.cal options to all rendering tools, not +just rcontrib/rxcontrib. Feature request from Peter A-B. + +Fixed slight bias in indirect calculation caused by ambient +collision detection, pointed out by Jon Sargent. New code +keeps track of rejected samples and sells them back to +later calls to get something closer to a true Poisson +sampling method. + +Altered rvu "origin" command to take shift amounts forward, +right, and up rather than taking an explicit origin, which +can be done easily enough with the "view" command. Peter A-B +requested (sort of). + +Added genglaze tool created by Taoning Wang to generate +spectral glazing materials based on CGDB data and models.
