RE: [Algorithms] Maximum Distance Point To AABB

[Tom F. <to...@mu...>]

I wouldn't worry about trying to bin the smaller mipmap levels - they are so
much less memory than the larger ones that it's pointless trying to bin them
- (a) you save very little memory, (b) even close-to things can use smaller
mipmaps (if they are edge-on) and (c) most hardware doesn't support having
missing small mipmaps - you'll only confuse it horribly.

Saving the larger mipmaps is obviously a win though.
