# Line 2672 | Line 2672 | put out as many color channels as specified in any -cs
2672  
2673   Added ability of mgf2rad to convert spectral data at least
2674   for light, glow, plastic, and metal primitive types.  Need
2675 < to use new '-s' option to get new output.
2675 > to use new '-s' option to get new output.  Added support for
2676 > new WGMDfunc type as well, which is considerably more flexible
2677 > at supporting different spectral components.
2678  
2679 < Added handling of spectral images to rcode2bmp script.
2679 > Added handling of spectral pictures (HSR) to rcode2bmp script.
2680  
2681   Minor change to rcollate to allow explicit byte records to
2682   be any specified length without checks against header input.
# Line 2718 | Line 2720 | Wrote rxpiece tool that will render pictures using til
2720   can handle different output formats and hyperspectral pictures.
2721   Only runs on a single machine, however -- no NFS locking on
2722   shared volumes.  Mainly a demonstration tool for RpictSimulManager
2723 < C++ class, but may have its uses.
2723 > C++ class, but later added to standard Rmakefile targets.
2724  
2725   Fixed a bug in BSDF sampling of sources pointed out by
2726   David Geisler-Moroder, which tended to overestimate specular
# Line 2740 | Line 2742 | results are still reported in RGB.
2742   Added accurate conversion of hyperspectral pictures to ra_xyze.
2743  
2744   Added hyperspectral picture conversion to ra_tiff, with accurate
2745 < color when targeting 16-bit/comp., LogLuv, and float utput,
2745 > color when targeting 16-bit/comp., LogLuv, and float output,
2746   and the approximate method for 24-bit RGB.
2747  
2748   Taoning added genssky -L option to specify global and diffuse
# Line 2820 | Line 2822 | half-maximum sizes of peaks in SIR and XML inputs.
2822   Changed default super-sampling in bsdf2ttree from 256 to 64,
2823   since there doesn't seem to be much benefit to the higher
2824   sampling rate for most BSDFs.
2825 +
2826 + Fixed problem with "mirror" primitive, which was not permitting
2827 + indirect rays to transmit through alternate material type.
2828 + Thanks to Jon Sargent for finding problem and help resolving it.
2829 +
2830 + Added experimental C++ based rxpiece tool to default installation
2831 + in makeall/Rmakefile.
2832 +
2833 + Added rcomb -mt option to transpose concatenation matrix.
