— Programs: Light —

ColCalc — 309 KB inclusive documentation; Windows 2000 and newer — February 2014.
The program ColCalc.exe version 1.02 (66 KB) calculates any colour along the Colour Wheel from the entered RGB values and the angle and returns the resulting RGB colour values. Good for Bryce if negative lights are used or to calculate appropriate neighbouring colours. An illustrated 3 page documentation is included.

HDRT9624 — 2.5 MB inclusive documentation; Windows 2000 and newer — March 2014.
The program HDRT9624.exe version 1.22 (134 KB) is a simple global tone-mapper. The program reads HDR RGBE RLE, 96-bit floating point TIFF and 96-bit floatmap PFM files and writes a tone-mapped 24-bit TIFF file. HDRI images in excess of 30,000 by 15,000 pixels can be processed provided there is sufficient memory available. The illustrated 9 page documentation is included.

UniHDRI — 328 KB inclusive documentation; Windows 2000 and newer — July 2017.
The program UniHDRI.exe version 1.00 (34 KB) generates a single colour spherical HDRI panorama 400 x 200 pixel. The primary colours red, green and blue, as well as a pixel multiplier can be entered. The resulting file is in the RGBE RLE2 format with the file type .hdr. This HDRI format can be used in most of the 3D CG programs. The illustrated 3 page documentation is included.

PanoRot — 3.3 MB inclusive documentation; Windows 2000 and newer — February 2016.
The program PanoRot.exe version 1.04 (88 KB) mirrors and rotates spherical HDRI and LDRI panoramas in 1° steps left and right. HDR (RGBE rle-2) and 96-bit TIF HDRI as well as 48-bit and 24-bit TIF LDRI in almost any size can be processed (tested up to 302 mega pixel). The illustrated 6 page documentation is included.

LightMap — 764 KB inclusive documentation; Windows 2000 and newer — September 2016.
The program LightMap.exe version 1.07 (49 KB) creates a spherical panorama from an IES photometric data file and saves it as 8-bit greyscale TIF (with and without gamma 2.2) for use as mask or gobo on a radial; and also as HDRI (RGBE rle-2) for use in IBL. An illustrated 6 page documentation is included.
