| 2394 |
|
Added "test" target to makeall to run unit tests. |
| 2395 |
|
|
| 2396 |
|
Modified bsdf2ttree to allow different parameters per input SIR file. |
| 2397 |
+ |
|
| 2398 |
+ |
Fixed issues with very large matrix files (> 2GB) in dctimestep, rmtxop, |
| 2399 |
+ |
and rcollate. |
| 2400 |
+ |
|
| 2401 |
+ |
Added -rf and -rb options to rmtxop to load front or back reflectance |
| 2402 |
+ |
matrix data from XML file rather than transmission. (Lars Grobe suggested.) |
| 2403 |
+ |
|
| 2404 |
+ |
Improved behavior for coincident surfaces with different materials. |
| 2405 |
+ |
Rather than returning one surface or the other based on floating-point |
| 2406 |
+ |
vagaries, opaque materials are now preferred over transparent ones. |
| 2407 |
+ |
If the materials are both transparent or both opaque, then whichever |
| 2408 |
+ |
surface appeared later in the scene description will be selected. |
| 2409 |
+ |
This came of a request for consistent behavior with legal CAD output |
| 2410 |
+ |
from Peter Apian-Bennewitz. |
| 2411 |
+ |
|
| 2412 |
+ |
Added explicit tests for on-edge intersections with polygons. This should |
| 2413 |
+ |
eliminate stray rays and tiny light leaks that often appear even in |
| 2414 |
+ |
well-constructed geometry. |
| 2415 |
+ |
|
| 2416 |
+ |
Added "-s up" option to pabopto2bsdf to allow for 180 degree symmetry, |
| 2417 |
+ |
meaning that data repeats after 180 degree rotation (as distinguished |
| 2418 |
+ |
from "-s bilateral" whose data is mirrored about a vertical plane). |
| 2419 |
+ |
Thanks to Helen Rose Wilson for the suggestion and informing me that |
| 2420 |
+ |
such a thing exists. |
| 2421 |
+ |
|
| 2422 |
+ |
Removed upper limit on number of modifiers in rcontrib. |
| 2423 |
+ |
|
| 2424 |
+ |
Put cap on maximum ambient gradient to avoid over-extrapolation of |
| 2425 |
+ |
poorly computed irradiance cache values. |
| 2426 |
+ |
|
| 2427 |
+ |
Added robjutil +T option to triangulate all faces in .OBJ description. |
| 2428 |
+ |
|
| 2429 |
+ |
Altered BSDF library to have both front and back diffuse transmittance |
| 2430 |
+ |
values, which can be different. This was necessary to avoid issues |
| 2431 |
+ |
caused by measurement and modeling discrepancies. |
| 2432 |
+ |
|
| 2433 |
+ |
Added pabopto2bsdf -g option to cull near-grazing scattering to avoid |
| 2434 |
+ |
issues with noise and negative values. |
| 2435 |
+ |
|
| 2436 |
+ |
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. 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 |
+ |
|
| 2445 |
+ |
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 |
| 2451 |
+ |
PRIMARIES= line is also produced on output from rpict or rvu with |
| 2452 |
+ |
the correct set of primaries based on how the system was compiled. |
| 2453 |
+ |
|
| 2454 |
+ |
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. |
| 2462 |
+ |
|
| 2463 |
+ |
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. |
