| 1284 |  | Added tone-mapping and monitor primary options to ra_bmp.  This gives | 
| 1285 |  | new functionality similar to normtiff and ximage.  It would be nice to | 
| 1286 |  | add this feature to the other ra_* programs as well...  someday. | 
| 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 lenths 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. |
