comment Implementing a black-body using Planck's Law in a 3D ray tracer
My XYZ values in part 3 of my question are way off. I know my implementation of Spectrum to XYZ conversion is correct because I've tested it against other data sets. Link to the formula for those interested: brucelindbloom.com/Eqn_Spect_to_XYZ.html

comment Implementing a black-body using Planck's Law in a 3D ray tracer
@Nathaniel In part 3 of my question I can't be sure if my claim is true or not because I'm not getting the XYZ values of D65 from a blackbody radiation with temperature of 6504K. So, either there is something wrong with my implementation of Planck's Law, or something else, hence my part 1 and 2.

@RonMaimon I'm trying to implement blackbody radiation, which is emitted according to Planck's Law as far as I can tell. And it needs to be in terms of wavelength, not frequency.

@dmckee I documented the units of the ones that I know.

@Vineet Menon no real significance. We could use a cuboid, but I went with a sphere.

@Georg The observer and the flashlight are invisible, just for the sake of it, so that they wouldn't absorb any of the energy.
