Increased polygon vertex limit to 512 in obj2mesh and obj2rad and added warning if this limit is exceeded. + +Added tone-mapping and monitor primary options to ra_bmp. This gives +new functionality similar to normtiff and ximage. It would be nice to +add this feature to the other ra_* programs as well... someday. + +Fixed long-standing bug in reported pixel ordering out of certain +protate commands. + +Added -p option to rcalc for "passive mode" that transmits +unrecognized input -- useful for substituting data in the +middle of a stream. + +Fixed a very obscure bug in rpict that caused a dark horizontal +line in certain cylindrical projections due to improper drawing +of the sky dome source in rt/srcdraw.c. + +Fixed problems with effective ray lenths computed for dielectric +and BRTDfunc materials. This was most evident in breakup of holodeck +views when VDISTANCE=True. + +Fixed rad so that 'scene' variable may consist only of inline commands. + +Fixed bug introduced in shadow caching routines where sources in the +middle of spheres were not illuminating properly. Thanks to Guilio +Antonutto for spotting this problem. + +Modified gensky behavior so if time is given with standard time zone +designation, any -m option is ignored. + +Added -n option to mkillum for (shared memory) parallel processing. + +Fixed a long-standing bug in parallel processing code that only +seemed to manifest with the new mkillum -n option, where rtrace +would deadlock upon termination. The reason it never showed up +before is because I always closed processes in the reverse order +of opening them in other programs. I went through and found similar +(potential) bugs in the rview device subprocess code and util/netproc.c. + +Corrected the normalization of the Gaussian reflectance model. This will +cause an increase in specularity for low-lying light sources. +Thanks to Don Walters of Boeing and Arne Duer of the Univ. of Innsbruck +for pointing out this error. The square root used for the two cosines +in the denominator of the normalization factor should not be present. +This was a serious mistake I made in the original model, which went +undiscovered (at least to my knowledge) for over a decade. I think +Bruce Walter of Cornell may have known about it, but I never heard +the details of his discovery.
