| 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. | 
| 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. | 
| 2526 | + |  | 
| 2527 | + | Added -P option to rcalc to pass formatted input when cond is <= 0. | 
| 2528 | + |  | 
| 2529 | + | Created rcrop utility for cropping matrices and pictures more | 
| 2530 | + | conveniently, correcting view information.  Expect it to be handy | 
| 2531 | + | for extracting rows and columns from matrices, mostly. | 
| 2532 | + |  | 
| 2533 | + | Changed pcomb so -o option elides original exposure values | 
| 2534 | + | from indented source headers. |
