Made reciprocity averaging default to "off" in bsdf2ttree, as it seems |
| 2605 |
|
to create more problems than it solves. |

==================== |
| 2608 |
+ |
Version 6.0 |
| 2609 |
+ |
|
| 2610 |
+ |
Extensive changes to enable spectral rendering, which defaults to "off" |
| 2611 |
+ |
to maintain backwards-compatibility with previous versions, with the |
| 2612 |
+ |
exception of the ambient file format, which is changed. The MAXCSAMP |
| 2613 |
+ |
macro, which defaults to 24, sets the maximum number of spectral samples. |
| 2614 |
+ |
The actual number of samples is set by the "-cs" option, which defaults |
| 2615 |
+ |
to 3 for rpict, rtrace, and rcontrib. The latter two programs support |
| 2616 |
+ |
straight spectral output, but rpict is initially restricted to |
| 2617 |
+ |
tristimulus output pictures. New pattern primitives "spectrum", |
| 2618 |
+ |
"specfile", and "specfunc" have been added as a means to specify |
| 2619 |
+ |
spectral reflectance, emittance, etc. to materials that still have |
| 2620 |
+ |
only 3 color channels. Those RGB channels will still affect the |
| 2621 |
+ |
spectrum if used. Unfortunately photon-mapping is currently broken when |
| 2622 |
+ |
spectral sampling is enabled, but we will fix this as soon as possible. |
| 2623 |
+ |
Calculation overhead appears to be approximately 10-15% for RGB |
| 2624 |
+ |
renderings compared to version 5.4a. |
| 2625 |
+ |
|
| 2626 |
+ |
Added spectral rendering to rvu as well, and made -cs and -cw |
| 2627 |
+ |
options standard across the rendering library. I also brought |
| 2628 |
+ |
mkillum, ranimove, rsensor, and mksource into the fold. These |
| 2629 |
+ |
tools were broken in the initial release. (Hopefully, they are |
| 2630 |
+ |
working now, but none have been tested as yet.) |
| 2631 |
+ |
There was also an indexing bug in the spectral->RGB conversions |
| 2632 |
+ |
that made reds into blues and vice versa, which has been fixed. |
