Added rsensor program to compute sensor signal for daylighting controls. Funding for this component was provided by the Architectural Energy Corporation in Boulder, CO, and directed by Zack Rogers. + +Added "planisphere" (stereographic) fisheye view type for traditional +daylighting analysis. Feature requested & explained by Axel Jacobs. + +Modified -c option to rtcontrib so it can take a number of input +rays to average over, rather than only produce a single accumulated +record (which can now be done with -c 0). + +===================== +Version 4.0 + +Added -n option to rvu to provide parallel rendering. + +****** COMPATIBILITY CHANGE ******** +Changed ".pic" extension to ".hdr" in all sources and documentation +to improve interoperability with other software, since this has become +the de facto extension for Radiance RGBE and XYZE pictures. Since file +extensions were never more than a convention in Radiance, this does not +affect operation, but may require the update of scripts, etc. written +by others that assume the ".pic" suffix for Radiance output. + +Added -N option to objview to support multiprocessing. + +Improved sampling of circular sources (source, sphere, ring types) with +quite a bit of help from David Geisler-Moroder. + +Added "rpict" and "rvu" variables to rad, and made these as well as +the "oconv", "mkillum" and "pfilt" variables accept an alternate +command path in each case. Change suggested by Lars Grobe based +on similar Radzilla (radz) facility by Carsten Bauer. + +Fixed rad -v N specification to use actual view name if one. + +Fixed error in mkillum calculation where it neglected indirect +source contributions from BTDF illum's. + +Added GMT and LATLONG header lines for Greenwich Mean Time and +degrees North Latitude / East Longitude. + +Added gendaylit to distribution (finally). + +Added ability in vwright(1) to get view from command line arguments. + +Created genklemsamp(1) utility to generate samples suitable for +BSDF-based annual calculations. This is the first Perl script to +be added to Radiance. Hopefully, others will follow. + +Added klems_int.cal file to compute Klems bins for windows. + +Created gentregvec utility to sample a particular sky and +evaluate average radiance over the standard Tregenza sky patches.
