This addition was suggested by Peter Apian-Bennewitz as an easier |

==================== |
| 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. |
| 2633 |
> |
|
| 2634 |
> |
Added i/o for spectral pictures to rmtxop, the first program that can |
| 2635 |
> |
ingest them. (Only rtrace, rcontrib, and rfluxmtx can render them.) |
| 2636 |
> |
New symbolic rmtxop -c options, such as RGB, XYZ, S (for scotopic) |
| 2637 |
> |
and M (for melanopic) make color conversions simpler. Alternatively, |
| 2638 |
> |
a reference matrix or picture may be given and the color space of |
| 2639 |
> |
that file will be used. The -C option takes either a symbolic |
| 2640 |
> |
color space or reference file and is "sticky," so it applies to |
| 2641 |
> |
all subsequent input files that do not have their own -c right ahead |
| 2642 |
> |
of them. |
| 2643 |
> |
|
| 2644 |
> |
Added spectral picture support to rcrop and radcompare. |
| 2645 |
> |
|
| 2646 |
> |
Added new utility, rmtxcomb, which is hard to type and hard to |
| 2647 |
> |
pronounce, and probably equally difficult to use. Sort of a |
| 2648 |
> |
combination of rmtxop and pcomb, it works with all the inputs and |
| 2649 |
> |
outputs that rmtxop handles, but allows for general expressions |
| 2650 |
> |
like those in pcomb for putting matrices together, working on |
| 2651 |
> |
an element at a time. (No resizing of matrices or accessing |
| 2652 |
> |
neighboring elements, as permitted in pcomb.) It saves memory |
| 2653 |
> |
over rmtxop by operating on a row at a time, so can handle |
| 2654 |
> |
input and output matrices with any number of rows. It does |
| 2655 |
> |
provide for a single matrix-multiplication operation at the end, |
| 2656 |
> |
which only requires memory for that final matrix. |
| 2657 |
> |
|
| 2658 |
> |
Added support for filtering hyperspectral images to pfilt. |
