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.
