|
scanner positions. These are 145 patches with identical |
| 2684 |
|
row counts to Tregenza, but starting from a different |
| 2685 |
|
azimuth and reversing row directions at adjacent altitudes. |
| 2686 |
+ |
|
| 2687 |
+ |
Added optimization for long argument lists and arrays in |
| 2688 |
+ |
the calcomp routines used for rendering and in rcalc, etc. |
| 2689 |
+ |
|
| 2690 |
+ |
Added error estimate spreading to ambient super-sampling |
| 2691 |
+ |
algorithm (-as) to improve performance especially in |
| 2692 |
+ |
scenes with sharp cut-offs. |
| 2693 |
+ |
|
| 2694 |
+ |
Added -i option to gendaymtx to match -i option of gendaylit. |
| 2695 |
+ |
Thanks to Yongqing for initial implementation. |
| 2696 |
+ |
|
| 2697 |
+ |
Changed rcrop so negative #rows or #cols counts back from end. |
| 2698 |
+ |
|
| 2699 |
+ |
Added rcomb -n option for multi-processing of very large matrices. |
| 2700 |
+ |
|
| 2701 |
+ |
Made it so rsplit and rlam can handle any number of input files |
| 2702 |
+ |
up to active open file descriptor limit. |
| 2703 |
+ |
|
| 2704 |
+ |
Taoning Wang added genssky tool for generating spectral sky |
| 2705 |
+ |
descriptions. |
| 2706 |
+ |
|
| 2707 |
+ |
Taoning added gensdaymtx utility based on gendaymtx, and |
| 2708 |
+ |
added epw2wea -a option to include required information. |
| 2709 |
+ |
|
| 2710 |
+ |
Fixed bug introduced in Auguest 2022 (5.4 release) in distant |
| 2711 |
+ |
light source sampling, which caused aiming failures. (Thanks |
| 2712 |
+ |
to Mike DiPompeo of LightStanza for reporting the issue.) |
| 2713 |
+ |
|
| 2714 |
+ |
Added rxpict rendering tool based on C++ RpictSimulManager class. |
| 2715 |
+ |
Multi-processing and spectral output are supported. |
| 2716 |
+ |
|
| 2717 |
+ |
Wrote rxpiece tool that will render pictures using tiling and |
| 2718 |
+ |
can handle different output formats and hyperspectral pictures. |
| 2719 |
+ |
Only runs on a single machine, however -- now NFS locking on |
| 2720 |
+ |
shared volumes. Mainly a demonstration tool for RpictSimulManager |
| 2721 |
+ |
C++ class, but may have its uses. |
| 2722 |
+ |
|
| 2723 |
+ |
Fixed a bug in BSDF sampling of sources pointed out by |
| 2724 |
+ |
David Geisler-Moroder, which tended to overestimate specular |
| 2725 |
+ |
contributions for some BSDFs. |
| 2726 |
+ |
|
| 2727 |
+ |
Added crude ability to read and convert spectra to RGB in ximage, |
| 2728 |
+ |
ra_bmp, ra_ps, and ra_rgbe programs. Also updated fast tone-mapping |
| 2729 |
+ |
library to handle spectral HSR inputs at the same time. HSR |
| 2730 |
+ |
input handling was added in a similar fashion to pcond and pvalue |
| 2731 |
+ |
for convenience. |
| 2732 |
+ |
|
| 2733 |
+ |
Added handling of hyperspectral images to normtiff, a handy program |
| 2734 |
+ |
for quickly tone-mapping Radiance RGBE, XYZE, and now hyperspectral |
| 2735 |
+ |
pictures, as well as IEEE float or LogLuv TIFFs. |
| 2736 |
+ |
|
| 2737 |
+ |
Added handling of hyperspectral pictures to pextrem, though |
| 2738 |
+ |
results are still reported in RGB. |
| 2739 |
+ |
|
| 2740 |
+ |
Added accurate conversion of hyperspectral pictures to ra_xyze. |
| 2741 |
+ |
|
| 2742 |
+ |
Added hyperspectral picture conversion to ra_tiff, with accurate |
| 2743 |
+ |
color when targeting 16-bit/comp., LogLuv, and float utput, |
| 2744 |
+ |
and the approximate method for 24-bit RGB. |
| 2745 |
+ |
|
| 2746 |
+ |
Taoning added genssky -L option to specify global and diffuse |
| 2747 |
+ |
illuminance values for output calibration. |
| 2748 |
+ |
|
| 2749 |
+ |
Created C++ class for rcontrib and example tool rxcontrib, which |
| 2750 |
+ |
is an optional compile in the src/rt directory. The output |
| 2751 |
+ |
model is more general in some respects and the operations more |
| 2752 |
+ |
efficient, but standard output is not supported, nor is ASCII |
| 2753 |
+ |
results data. |
| 2754 |
+ |
|
| 2755 |
+ |
Added experimental source-skipping method to rpict for scenes |
| 2756 |
+ |
with large number of light sources. Currently works with |
| 2757 |
+ |
rcontrib and separate srcsamp image-processing tool. Controlling |
| 2758 |
+ |
rpict options are -dS for skip bitmap specification and -dC |
| 2759 |
+ |
for correction coefficient image. Compile using -DSSKIPOPT |
| 2760 |
+ |
to include this option. |
