Added automatic flushing to the output of total, except when the -r |
| 2455 |
|
(running subtotals) option is used. |
| 2456 |

|
| 2457 |

Improved behavior of little-used -aw option, so that it avoids sea-level |
| 2458 |
+ |
rise caused by adding its own estimate back into the ambient level remainder. |
| 2459 |
+ |
It ended up being simple enough to derate the final average by the factor |
| 2460 |
+ |
corresponding to average surface absorpition, thus removing the average |
| 2461 |
+ |
from the final bounce estimate. |

Introduced ies2rad upgrades by Randolph Fritz. Randolph says it |
| 2464 |
+ |
fixes the following problems: |
| 2465 |
+ |
|
| 2466 |
+ |
1. Generates correct Radiance geometry for spheres in 1995, 2002, |
| 2467 |
+ |
and 2019 IES files. |
| 2468 |
+ |
|
| 2469 |
+ |
2. Generates correct Radiance geometry for vertical cylinders that |
| 2470 |
+ |
are taller than they are wide. |
| 2471 |
+ |
|
| 2472 |
+ |
3. Ignores the file source ("File Generation Type") field in the |
| 2473 |
+ |
2019 version of the file, which would otherwise be incorrectly used |
| 2474 |
+ |
as an output multiplier. |
| 2475 |
+ |
|
| 2476 |
+ |
It also offers the following enhancements: |
| 2477 |
+ |
|
| 2478 |
+ |
1. Shape information is included in the .rad file comments. |
| 2479 |
+ |
|
| 2480 |
+ |
2. 1995, 2002, and 2019-version luminous opening geometry is |
| 2481 |
+ |
accounted for. |
| 2482 |
+ |
|
| 2483 |
+ |
3. The 2002 and 2019 IES file versions are recognized and |
| 2484 |
+ |
processed appropriately. |
| 2485 |
+ |
|
| 2486 |
+ |
4. I have made an attempt to do something intelligent with less |
| 2487 |
+ |
common "luminous opening" shapes in the 1995, 2002, and 2019 versions |
| 2488 |
+ |
of the standard, though I have not implemented any support for new |
| 2489 |
+ |
geometry; approximations are substituted and warning messages issued. |
| 2490 |
+ |
Unfortunately, this code is not tested, since I don't have any IES |
| 2491 |
+ |
files that use these shapes. |
| 2492 |
+ |
|
| 2493 |
+ |
Added support for depth-of-field blurring in vwrays using -pd option. |
| 2494 |
+ |
Also, made -c count work with vwrays -i, producing multiple samples |
| 2495 |
+ |
per indicated pixel position. At the same time, support for the -pd |
| 2496 |
+ |
option was added to rtpict, which calls on vwrays for its samples. |
| 2497 |
+ |
|
| 2498 |
+ |
Fixed issue with BSDFs that didn't obey reciprocity, where direct |
| 2499 |
+ |
sampling wasn't following exactly with indirect sampling. This was |
| 2500 |
+ |
discovered and reported by Jon Sargent. |
| 2501 |
+ |
|
| 2502 |
+ |
Created checkBSDF tool to test XML BSDF reciprocity and perform similar |
| 2503 |
+ |
sanity checks. |
