Matthias Schiffer	248a641035	Restructure crates ... Get rid of the arbitrary bin/lib split and instead move as much as possible into the bin crate, which becomes the main crate again. The types and NBT handling are moved into separate crates, so they can be reused by nbtdump and regiondump.	2023-08-20 17:00:10 +02:00
Matthias Schiffer	05a8056cbf	Add documentation comments for all items	2023-08-20 11:21:29 +02:00
Matthias Schiffer	0842cb4ec2	Rename library crate to minedmap-core ... Rustdoc can't deal with a bin and lib crate with the same name.	2023-08-18 19:20:21 +02:00
Matthias Schiffer	427a992897	minedmap/tile_renderer: keep HashSet of populated regions ... Rather than attemping to read the file metadata, it's more elegant to check whether a tile is supposed to be available first.	2023-08-15 20:48:41 +02:00
Matthias Schiffer	722fe00d77	minedmap: move inputs to processing steps from run() to new()	2023-08-15 18:45:38 +02:00
Matthias Schiffer	6a82fcc9b4	minedmap/tile_renderer: terminate on errors ... Only the processing step may fail for individual tiles (when a region is currently being saved when attempting to process it), the other steps should never fail.	2023-08-15 18:31:53 +02:00
Matthias Schiffer	155171803d	minedmap/tile_renderer: parallel processing	2023-08-15 17:43:58 +02:00
Matthias Schiffer	b5980b82af	minedmap/tile_renderer: async region cache ... Prepare for sharing the region cache between multiple threads by making lookup/load async.	2023-08-15 17:42:27 +02:00
Matthias Schiffer	21035a1f7f	Move coord offset to new util module, make more efficient ... div_floor_mod() generates inefficient code. For power-of-2 divisors, shift and mask can be used instead.	2023-08-06 11:26:08 +02:00
Matthias Schiffer	b80d9ee420	minedmap/tile_renderer: make biome HashMap more efficient ... Using a u32 instead of a tuple makes the hash calculation faster, because the fields don't have to be hashed separately.	2023-08-06 00:07:46 +02:00
Matthias Schiffer	84bee6d6d9	minedmap: add region cache ... Cache the last loaded processed regions.	2023-08-05 20:26:59 +02:00
Matthias Schiffer	7b46adf6e7	minedmap: split up big types by adding Boxes ... Make these values faster to move around, and optimize their size when used in Options.	2023-08-05 18:11:39 +02:00
Matthias Schiffer	7d231b92ea	Format let-else blocks ... Use nightly rustfmt to format let-else.	2023-08-05 10:46:47 +02:00
Matthias Schiffer	deb33814ee	minedmap/tile_renderer: avoid calling block_color() more often than necessary ... Collect all biome indices/weights for a chunk and deduplicate using a hash map.	2023-08-03 23:07:16 +02:00
Matthias Schiffer	fb712cd2f5	Store per-region biome list in IndexSet ... Index into the biome list instead of duplicating the biome data for each coordinate. This reduces the size of the processed data and speeds up encoding/decoding.	2023-08-03 23:07:16 +02:00
Matthias Schiffer	c38f00e411	minedmap/tile_renderer: implement biome smoothing ... Rather than the diamond-shaped kernel used by the old implemenation, we now use the approximation of a Gauss filter. In addition, the kernel size is decreased, reducing the strength of the blur effect.	2023-08-03 19:06:20 +02:00
Matthias Schiffer	b650b096ef	resource: return block color as float vector ... Deferring conversion to integers is convenient for biome smoothing.	2023-08-03 18:31:45 +02:00
Matthias Schiffer	0a485343a0	resource: do not require Biome to get color for all block types ... Only grass, foliage and water have biome-dependent colors.	2023-08-03 18:28:57 +02:00
Matthias Schiffer	45171aa26a	minedmap/tile_renderer: factor out block_color_at() from render_chunk() ... Also pass in a few more values to prepare for biome smoothing.	2023-08-03 18:12:56 +02:00
Matthias Schiffer	8e848394cd	minedmap/tile_renderer: add biome_at() helper ... Retrieve the biome at a given coordinate, possibly offset by a number of blocks.	2023-08-03 18:02:26 +02:00
Matthias Schiffer	dee00e7a02	minedmap/tile_renderer: add coord_offset() helper	2023-08-03 18:02:26 +02:00
Matthias Schiffer	35bbd167ba	minedmap/tile_renderer: load 3x3 neighbourhoods of regions ... Prepare for biome smoothing by always loading neighbouring regions.	2023-08-03 18:02:26 +02:00
Matthias Schiffer	a30266f67f	minedmap/tile_renderer: take into account neighboring regions ... Biome smoothing uses biome data from neighboring regions. Collect paths and timestamps from 3x3 region groups.	2023-08-03 17:55:39 +02:00
Matthias Schiffer	e39f48d8fe	types: use const generics for more generic coordinate types ... Enum support in const generics would be even nicer, but for now the integer generic is the best Rust can do.	2023-08-02 02:55:13 +02:00
Matthias Schiffer	80781c9c20	minedmap: skip generation steps when the inputs are unchanged	2023-07-31 00:23:06 +02:00
Matthias Schiffer	6077138292	Add version field to file metadata	2023-07-30 21:48:58 +02:00
Matthias Schiffer	628a702fd7	Store source modified timestamp with processed, lightmap and map tiles ... Allows to check whether the source is newer than the last update of the output files.	2023-07-30 21:19:24 +02:00
Matthias Schiffer	f9fc9efe8d	Revert "minedmap: store region list in BTreeSet" ... This reverts commit b53d34da3d. With the change of the mipmapper data structure, we need a conversion step anyways, so we can keep using the Vec before mipmapping.	2023-07-02 22:19:35 +02:00
Matthias Schiffer	86382772c3	minedmap/tile_renderer: print tile path relative to output directory ... We will use strings of the same format for mipmap tile paths.	2023-07-02 20:05:57 +02:00
Matthias Schiffer	b1f7f759f1	minedmap: introduce generic tile path function, pass mipmap level	2023-07-02 18:58:08 +02:00
Matthias Schiffer	b53d34da3d	minedmap: store region list in BTreeSet ... We want to have a sorted list in the end anyways to make metadata generation deterministic, and we don't have to worry about deduplication of coordinates when generating mipmap tile lists.	2023-07-02 18:16:35 +02:00
Matthias Schiffer	007ce010d4	minedmap: rename RegionCoords to TileCoords ... With mipmapping, coords will not always correspond to regions anymore.	2023-07-02 15:11:16 +02:00
Matthias Schiffer	17a02dc74c	minedmap: use fs helpers	2023-06-01 23:14:35 +02:00
Matthias Schiffer	31eb92864c	Split up BlockInfo type ... By storing block types and depth values separately, the processed world data can be compressed better, decreasing data size by ~10%.	2023-05-06 00:52:40 +02:00
Matthias Schiffer	2d5eec13c2	world/layer: move Option into BlockInfo struct ... Preparation for top_layer() cleanup.	2023-05-05 23:29:57 +02:00
Matthias Schiffer	25710bb1ed	Move block_color() to new module	2023-05-04 22:18:15 +02:00
Matthias Schiffer	2dd9283d95	minedmap: move some internal functions out of impl blocks	2023-05-01 17:51:38 +02:00
Matthias Schiffer	1a5e8894fe	minedmap: split up main module	2023-04-30 11:07:47 +02:00
