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. |
