Checkerboard Challenge

Every layer uses ~50% of the remaining pixels (if you draw front to back).


Not necessarily correct. 1 layer can take op way less than 50%. and also way more.

How many layers can a mid range modern GPU render at 640x480@60hz? I know it'll be some daft number, but would be interesting for comparison ;-)

I was like "wait, what?" when I read "Every lawyer uses ~50% of the remaining pixels (if you draw front to back)."

I accept only one lawyer to use 50 % of the remaining pixels, because he's always been Frank to us.

You're not serious, right? We're talking about millions of polygons.

Yeah. Keep adding layers until you start dropping frames. How many millions of layers?

it will definitely not be millions. Hundreds to few thousands (if not).

@SCA: I checked this typical case:
BB Image

the 4 layers (light to dark) occupy 50.4% , 24.9% , 11.8% and 6.1%

indeed its possible to create far less coverage, but will most likely not work well within the given rules

Announcement for anyone who wants to follow discussions of the Checkerboard Challenge:

Britelite and I will be appearing as guests (together with Urs) in the Mystery Demoscene Theater 9000 livestream show tomorrow night at 21:00 UTC (22:00 CET). We are quite certainly going to be discussing the challenge, among other things. :)

Naive GPU attempt in Shadertoy: https://www.shadertoy.com/view/ltXfRn

Has the depth limit set at 10k layers, but it's quite rare for everything to align to get any decent depth.
