The third one is more than just Bias. I will be explaining this in my book. (I was already working on a shader book before Coop started this process. I plan to let Deecey handle the basics for free on the SM site, and you'll have to buy the book to get the intermediate and advanced stuff.)
Robyn and CobaltDream have been reviewing the book, so they already know some of the stuff that are necessary to understand what I'm doing here in the third one. I'm using the "Complement" function.
C(x) = 1 - x
The last one is a function I came up with called IBias:
IBias(a, b) = C(Bias(C(x), 1-b))
It's very handy.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
