| 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. | 
| 2535 | + |  | 
| 2536 | + | Added getinfo -r option, which is similar to -a except it will | 
| 2537 | + | replace indicated lines with new ones. | 
| 2538 | + |  | 
| 2539 | + | Slight change to vwrays -d option to not spit out "-ld-", and to | 
| 2540 | + | produce "-ld+" without requiring input picture as argument. | 
| 2541 | + |  | 
| 2542 | + | Added automatic overture calculation to rtpict with -n > 1 if | 
| 2543 | + | ambient cache is on and file is named.  If straight image output | 
| 2544 | + | is requested, we randomize all samples and avoid cache collisions. | 
| 2545 | + |  | 
| 2546 | + | Added cnt -s option to shuffle output. | 
| 2547 | + |  | 
| 2548 | + | Fixed issue with divide-by-zero errors in the ambient super-sampling | 
| 2549 | + | routine discovered by Jon Sargent of Solemma.  This affected regions | 
| 2550 | + | that had zero radiance, such as black backgrounds or unlit areas | 
| 2551 | + | with -av 0 0 0, when super-sampling was effectively disabled, causing | 
| 2552 | + | some loss in accuracy of the results. | 
| 2553 | + |  | 
| 2554 | + | Updated Klems Half- and Quarter-bases to match angles currently used | 
| 2555 | + | in WINDOW. | 
| 2556 | + |  | 
| 2557 | + | Eliminated most aiming failures for triangular light sources, at the | 
| 2558 | + | expense of conservative sampling near the centroid.  Thanks to | 
| 2559 | + | David Geisler-Moroder for his help on this. |
