Increased default dynamic range from 32 to 100 in pcond and normtiff. |
| 2437 |

|
| 2438 |
|
Added -o and -n options to genbox to create .OBJ output and segment |
| 2439 |
< |
edges and corners for transparent materials. |

edges and corners for transparent materials. Also added -s option |
| 2440 |

to control smoothing for .OBJ and Radiance with segmented rounding. |
| 2441 |

|
| 2442 |

Made it so robjutil with the +r option for Radiance output now |
| 2443 |

produces normal smoothing unless normals are removed with -n. |
| 2444 |

Added exposure preservation to pcompos when possible (i.e., when |
| 2446 |

there is only one input or inputs agree on exposure). |
| 2447 |

|
| 2448 |

Added -DSHARP_RGB compile-time option to use sharp RGB color space |
| 2449 |

rather than historic default. This can make for more accurate color |
| 2450 |

calculations, but requires that materials be recalibrated. The |

PRIMARIES= line is also produced on output from rpict or rvu with |

the correct set of primaries based on how the system was compiled. |

Added automatic flushing to the output of total, except when the -r |

(running subtotals) option is used. |

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. |

It ended up being simple enough to derate the final average by the factor |

corresponding to average surface absorpition, thus removing the average |

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. |

|

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. |

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 |

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. |
| 2504 |
> |
|
| 2505 |
> |
Added -O option to pvalue and pextrem to report watts/sr/m^2 even if |
| 2506 |
> |
picture is XYZE. |
| 2507 |
> |
|
| 2508 |
> |
Made subtle changes to header i/o routines to preserve alignment in |
| 2509 |
> |
binary file formats to enable memory-mapping. Implemented memory-mapped |
| 2510 |
> |
matrix loading in rmtxop for binary double files. |
| 2511 |
> |
|
| 2512 |
> |
Removed ambient value sorting, which was written when ambient caches |
| 2513 |
> |
could overwhelm available memory. This is rarely the case these days, |
| 2514 |
> |
and the added code complexity and updating of cache values with LRU |
| 2515 |
> |
counts dirties pages that would otherwise remain clean, so it was |
| 2516 |
> |
often a loss even when VM was an issue. |
| 2517 |

|
| 2518 |
> |
Added iso2klems script to compute a Klems BSDF based on specular |
| 2519 |
> |
and diffuse measurements as a function of incident angle. |
| 2520 |
> |
|
| 2521 |
> |
Fixed issue with over-counting diffuse component during aBSDF |
| 2522 |
> |
peak extraction. |
| 2523 |
> |
|
| 2524 |
> |
Added dctimestep -x and -y options to specify image dimensions |
| 2525 |
> |
for multiple outputs corresponding to result vectors. |
