# Line 1256 | Line 1256 | Added -I option to replmarks for mesh instancing.
1256   Made similar change for virtual sources to allow modifiers and aliases
1257   on the mirror and prism types to work properly.

1259 > Rob Guglielmetti added -lw and -lh options to falsecolor to control the
1260   legend dimensions.  Made it so -lw 0 and/or -lh 0 turns legend off.
1261  
1262   Made it so pcompos will read everything from a stream even if it doesn't
# Line 1287 | Line 1287 | add this feature to the other ra_* programs as well...
1287  
1288   Fixed long-standing bug in reported pixel ordering out of certain
1289   protate commands.
1290 +
1291 + Added -p option to rcalc for "passive mode" that transmits
1292 + unrecognized input -- useful for substituting data in the
1293 + middle of a stream.
1294 +
1295 + Fixed a very obscure bug in rpict that caused a dark horizontal
1296 + line in certain cylindrical projections due to improper drawing
1297 + of the sky dome source in rt/srcdraw.c.
1298 +
1299 + Fixed problems with effective ray lengths computed for dielectric
1300 + and BRTDfunc materials.  This was most evident in breakup of holodeck
1301 + views when VDISTANCE=True.
1302 +
1303 + Fixed rad so that 'scene' variable may consist only of inline commands.
1304 +
1305 + Fixed bug introduced in shadow caching routines where sources in the
1306 + middle of spheres were not illuminating properly.  Thanks to Guilio
1307 + Antonutto for spotting this problem.
1308 +
1309 + Modified gensky behavior so if time is given with standard time zone
1310 + designation, any -m option is ignored.
1311 +
1312 + Added -n option to mkillum for (shared memory) parallel processing.
1313 +
1314 + Fixed a long-standing bug in parallel processing code that only
1315 + seemed to manifest with the new mkillum -n option, where rtrace
1316 + would deadlock upon termination.  The reason it never showed up
1317 + before is because I always closed processes in the reverse order
1318 + of opening them in other programs.  I went through and found similar
1319 + (potential) bugs in the rview device subprocess code and util/netproc.c.
1320 +
1321 + Corrected the normalization of the Gaussian reflectance model.  This will
1322 + cause an increase in specularity for low-lying light sources.
1323 + Thanks to Don Walters of Boeing and Arne Duer of the Univ. of Innsbruck
1324 + for pointing out this error.  The square root used for the two cosines
1325 + in the denominator of the normalization factor should not be present.
1326 + This was a serious mistake I made in the original model, which went
1327 + undiscovered (at least to my knowledge) for over a decade.  I think
1328 + Bruce Walter of Cornell may have known about it, but I never heard
1329 + the details of his discovery.
1330 +
1331 + Enabled the -p option for primary conversion without tone-mapping
1332 + in ra_bmp.  Also provides for XYZE input conversion to RGB.
1333 +
1334 + Fixed what I consider a bug in pvalue -o when taking XYZE files on input,
1335 + where it was inappropriately undoing the exposure value so that it always
1336 + reported radiance rather than XYZ values with Y in cd/m^2.
1337 +
1338 + Made it so ra_bmp only produces run-length encoded 8-bit output for
1339 + grayscale images that are tone-mapped.  This minimizes circumstances
1340 + under which output scanline order is reversed.
