Description
This started as a test scene for some coding experiments for auto correcting/adjusting of white balance based in part upon Gustav Kirchhoff's theory on black body radiation. And looked nice enough to share.

Well, first I was working on a way to do renders with no noise, that worked fine, unfortunately it gave heavy banding effects under some conditions and had to be scrapped, for now. I worked on white balance instead.

Each glass sphere contains a black body of different temperature, from 1100K (red) to 9900K (blue), laid out in a spiral. The emission of each have been normalised in the visible range as the range is several orders of magnitude in difference between the red and blue, as can be seen here . Next is to extend this to regular materials as very few materials are black.

If the range of colours look familiar, it isn't surprising as they are, for instance, often seen in the sky during the day. Rendered in a nice and large 16:9 format. Enjoy.

Update:
