I'm kind of confused by this article.
There is a formula in it :
Bias = (float)DepthBias * 2**(exponent(max z in primitive) - r) + SlopeScaledDepthBias * MaxDepthSlope;
First , what's ** after the number "2" ? Is it a typo ?
Second , about this part , exponent(max z in primitive) - r , could someone give me a more clear explanation ? It doesn't make any sense to me.
Thanks in advance.
