# Line 2671 | Line 2671 | put out as many color channels as specified in any -cs
2671   (default is 3 for RGB).
2672  
2673   Added ability of mgf2rad to convert spectral data at least
2674 < for light, glow, plastic, and metal primitive types.
2674 > for light, glow, plastic, and metal primitive types.  Need
2675 > to use new '-s' option to get new output.
2676  
2677   Added handling of spectral images to rcode2bmp script.
2678 +
2679 + Minor change to rcollate to allow explicit byte records to
2680 + be any specified length without checks against header input.
2681 +
2682 + Added new hemisphere type to rfluxmtx, "h=cie" for CIE sky
2683 + 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.
