| 2396 |  | Modified bsdf2ttree to allow different parameters per input SIR file. |

| 2398 | < | Fixed issues with very large matrix files (> 2GB) in dctimestep, rmtxop, and rcollate. |

| 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. |

| 2412 | > | Added explicit tests for on-edge intersections with polygons.  This should |

| 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). |
