Added DBLUR variable to ranimate and pmdblur script to handle simultaneous |
| 1398 |
< |
motion and depth-of-field blurring. |

Added setting of focus distance in rvu ("focus" command) and rholo |
| 1401 |
|
('f'/"frame" command). |
| 1402 |

|
| 1403 |

Changed default remote shell in ranimate to "ssh" rather than "rsh", |
| 1404 |
+ |
which has been abandoned on most Unix systems due to security issues. |
| 1405 |
+ |
|
| 1406 |
+ |
Fixed behavior of source primitive using illum with no alternate |
| 1407 |
+ |
material. These now become transparent so one can see the sky or |
| 1408 |
+ |
light-probe background for use in image-based lighting. Previously, |
| 1409 |
+ |
the user needed to specify the background glow as the alternate |
| 1410 |
+ |
material for a distant illum source to behave properly. (This still |
| 1411 |
+ |
works.) |
| 1412 |
+ |
|
| 1413 |
+ |
Fixed some minor problems and inconsistencies with 16-bit/channel |
| 1414 |
+ |
TIFF i/o in ra_tiff. |
| 1415 |
+ |
|
| 1416 |
+ |
Created mksource program to generate distant sources for improved |
| 1417 |
+ |
image-based lighting with light probes. |
| 1418 |
+ |
|
| 1419 |
+ |
Changed ambient calculation so that -ad will not limit recursion |
| 1420 |
+ |
depth, and a minimum of 27 samples will be sent out for each stored |
| 1421 |
+ |
ambient value, or 3 samples if -aa is 0 (caching off). |
| 1422 |
+ |
|
| 1423 |
+ |
Added -oM option to rtrace to report material (rather than modifier) |
| 1424 |
+ |
for cases where actual material is aliased or further up modifier chain. |
| 1425 |
+ |
|
| 1426 |
+ |
Rearranged the way ray contributions are computed so that it might be |
| 1427 |
+ |
possible to use rtrace to derive daylight coefficients and optical |
| 1428 |
+ |
transfer functions. The new -oTW option of rtrace produces color |
| 1429 |
+ |
contribution weights for each ray, which combined with the -ti (or -tI) |
| 1430 |
+ |
option permits the contribution of selected surfaces or sources to |
| 1431 |
+ |
be determined. Using the -oTW option, one should also specify |
| 1432 |
+ |
options "-dt 0 -aa 0 -as 0" for optimal results. In particular, |
| 1433 |
+ |
one cannot expect reasonable tallies with -ab >= 1 and irradiance |
| 1434 |
+ |
caching on (-aa > 0). |
| 1435 |
+ |
|
| 1436 |
+ |
The same code modifications included a change to the indirect computation |
| 1437 |
+ |
with caching switched off (-aa 0). Whereas before, the number of secondary |
| 1438 |
+ |
rays after the first bounce were half of the previous generation, they are |
| 1439 |
+ |
now determined by the surface reflectance, making for a better and faster |
| 1440 |
+ |
calculation. It should now be possible to compute many bounces with -aa 0, |
| 1441 |
+ |
which used to be prohibitively expensive. |
| 1442 |
+ |
|
| 1443 |
+ |
Added -T option to xshowtrace to trace rays to light sources. |
| 1444 |
+ |
|
| 1445 |
+ |
Added meta2bmp program to produce BMP files from metafile graphics. |
