Fixed rad so that 'scene' variable may consist only of inline commands. |

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. |

Modified gensky behavior so if time is given with standard time zone | 
| 1310 | 
+ | 
designation, any -m option is ignored. |

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 |

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. |

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. |
