Oops, maybe saying I’d have it “done soon” was a bad idea. Anyway, I have not yet been able to finish the detailed documentation, but here’s the update for now:
The changes in this update are described in my previous post. As for the problem with the new absorption calculations, I instead used the formula in v2.1 and removed an unnecessary step. Some of the glass materials have changed as a result, but they should be more correct.
I’ll be updating the top post when I finish the documentation!
