Matthias Schiffer	c7e04649ff	Resource: Biome: add 1.19 biomes ... Add the new biome temperature and rainfall values, as found in decompiled Minecraft code: - Deep Dark uses the same the values as plains - Mangrove Swamp has the same temperature/rainfall as regular Swamp, but a different water color	2022-10-16 13:14:31 +02:00
Andrew Cox	600a20cde6	Update to compile on Mac OS (#26)	2022-07-01 23:27:58 +02:00

Matthias Schiffer	37340926f4	MinedMap: fix warning for unused fscanf result	2021-12-19 23:11:21 +01:00
Matthias Schiffer	fac2e4c8da	World: Chunk: add support for unordered sections ... MC1.18 doesn't always store sections sorted by their Y value, possibly related to "optimize world".	2021-12-12 12:18:18 +01:00
Matthias Schiffer	a2fe33ef1f	World: Section: add support for Int tag section Y values ... For some reason, MC1.18 sometimes uses Int instead of Byte tags for section Y values after "optimize world". Add support for this (but still only accept values that fit in a int8_t).	2021-12-12 12:15:31 +01:00
Matthias Schiffer	d18e004743	World: Section: fix biome palette size check ... We were accidentally checking the block type palette size.	2021-12-12 10:28:17 +01:00

Matthias Schiffer	76e5d322b1	Resource: Biome: add biome palette name mapping ... For now we will continue to use the numerical biome IDs internally, as our biome storage format is based on these IDs.	2021-12-11 22:50:23 +01:00
Matthias Schiffer	aacea26716	World: add support for negative Y coordinates and MC 1.18 chunks ... MC 1.18 biomes are not handled yet.	2021-12-11 22:50:23 +01:00

Matthias Schiffer	457e993c92	Introduce separate types for block/section/chunk indices ... Newtypes are cumbersome in C++, so this is mostly documentation for now. Also replace lots of questionable uses of size_t with int or types with explicit width and add a few comments for constants.	2021-12-11 22:50:23 +01:00
Matthias Schiffer	d4be401bcd	Resource: Biome: fix integer underflow ... Explicitly cast height value to signed integer to fix incorrect biome color values below a height of 64.	2021-12-11 22:28:22 +01:00

Matthias Schiffer	fdce587c74	build: update to modern CMake, use pkg-config for zlib and libpng ... Starting with CMake 3.7, we can avoid dealing with individual variables for include dirs, libraries, ... for dependencies found using pkg-config, and instead just reference them using an imported target.	2021-08-24 13:14:48 +02:00
Matthias Schiffer	73e5c12cde	Rename .inc files to .inc.cpp for better language detection by editors and Github	2021-06-25 19:43:14 +02:00
Matthias Schiffer	af1afc3315	Biome: add Dripstone Caves and Lush Caves ... Temperature and downfall values were taken from the Caves & Cliffs: Part II Preview datapack.	2021-06-24 19:28:25 +02:00
Matthias Schiffer	0a42605a2b	Add Minecraft 1.17 block types, update all color values	2021-06-24 19:28:25 +02:00
Matthias Schiffer	9ac3b00b6e	Make region iteration more efficient for sparse worlds ... Do not iterate over each region coordinate in the bounding box. Closes #12	2021-02-13 11:06:30 +01:00
Matthias Schiffer	c06af49068	Info: restructure mipmap level data structure	2021-02-13 11:06:30 +01:00

Matthias Schiffer	d2802b73f5	Info: make tile existence map mor efficient for sparse worlds ... Explicitly list the coordinates where tiles exist instead of including a full array with the size of the bounding box.	2021-02-13 11:06:21 +01:00
Matthias Schiffer	0ebc895ec0	Info: print concise JSON ... Reduce size by removing pretty-printing	2021-02-13 10:20:19 +01:00
Aaron Webster	367078178f	Change BlockType from struct to class ... Fixes the -Wmismatched-tags compilation warning.	2020-09-16 18:14:09 -07:00
Matthias Schiffer	3ec83c8cf8	Compare file contents with old data before writing ... Do not writeoutput files when their content hasn't changed. This saves time for incremental generation (as compressing a PNG takes much longer than decompressing it) and avoids modification timestamp updates that might trigger subsequent generation steps.	2020-06-20 15:01:52 +02:00
Matthias Schiffer	ef69a34034	PNG: export format byte count	2020-06-20 15:01:09 +02:00

Matthias Schiffer	eb831608e0	Add smooth transitions between biomes ... Simliar to the way biome transitions are rendered in Minecraft itself, add smoothing by averaging biome-based colors over all biome values with distance ≤3 (1-norm).	2020-06-20 12:15:32 +02:00
Matthias Schiffer	623d70ec9e	More preparation for biome smoothing	2020-06-20 11:40:29 +02:00

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	dc97c4a8c1	PNG: add support for grayscale images without alpha	2020-06-20 00:58:08 +02:00
