Vladimír Vondruš	8f8dcd0076	doc: adapt the atlas doc image generator to latest changes. I made the binary data use 16-bit integers instead of 32-bit to make them occupy less space and forgot to update it here. Also they're in a different path now.	3 years ago

doc: adapt the atlas doc image generator to latest changes.

I made the binary data use 16-bit integers instead of 32-bit to make
them occupy less space and forgot to update it here. Also they're in a
different path now.

TextureTools: new landfill atlas packer.

Just the dumbest possible idea I had, and it compares surprisingly well
in both efficiency (~comparable to stb_rect_pack) and speed
(significantly faster than stb_rect_pack with tons of tiny images,
slower with larger ones -- would probably need to SIMD Math::max() and
such, haha). It's the very first implementation without any additional
improvements I have in mind, so it'll likely improve further.

Includes a benchmark with a bunch of "datasets" extracted from both
fonts and large glTF models. The stb_rect_pack file isn't commited as
it's not useful apart from this single benchmark, put it to
AtlasTestFiles/ and recompile.

TextureTools: doc snippet and sample output for atlasArrayPowerOfTwo().

Finally, sorry it took over a year. I did the visualization for the
article, it'd be sad to not use it. And add a link to the article too.
