Matthias Schiffer	f539d668eb	Collect biome data ... We store the biome data as grayscale images, as biome indices are represented as bytes and we get PNG compression for free.	2020-06-20 00:58:08 +02:00

Matthias Schiffer	ae68c3bab4	Add quirk for stone_slab rename ... The old stone_slab block from pre-1.14 has been renamed to smooth_stone_slab, and the name stone_slab was reused for a new block. Resolve the palette entry depending on the chunk's dataVersion.	2019-05-25 19:51:28 +02:00

Matthias Schiffer	0bdf249307	Add biome color computation ... Rather than using fixed values for all biomes, generate grass and foliage colors based on (height-dependent) temperature and rainfall parameters. This changes a lot of colors; in general, the new colors should be closer to the actual Minecraft rendering. It also fixes a few colors that were completely off (like in the badlands biomes) and adds the MC 1.13 biomes (which were rendered in black). Some of the newer biomes (warm/cold/... oceans) don't have proper parameters yet, and we do not derive the water color from the biome yet. Fixes #1.	2018-11-08 17:49:28 +01:00
