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. |
