Using the black body radiation concept, we can compute XYZ of all black-body illuminant. Prediction of this illuminants seems to be very close to CIE recommended illuminants such as CIE illuminant A
Let's show a quick example. We know illuminant A 2856K has 10 degree observer based X =111.144, Y=100, Z=35.200
Now, lets compute using our black body illuminant formula
get_XYZ_of_blackbody(2856).*100
ans =
111.1385 100.0000 35.2127
Pretty close! :)
Have fun!
