cubiomes
Cubiomes is a standalone library, written in C, that mimics the Minecraft biome and feature generation. It is intended as a powerful tool to devise very fast, custom seed finding applications and large scale map viewers.
Audience
You should be familiar with the C programming language, also a basic understanding of the Minecraft biome generation process would be helpful. A POSIX environment is required to compile the finders library and examples, but the core generator library may also work on other platforms.
Documentation
There is a reference document for the generator layers which contains a summary for most generator layers and their function within the generation process.
Example
There are two example programs in this repository which can be compiled using the makefile provided.
Finding Quad-Witch-Huts at a Specific Location
This classic type of finder uses several optimisations reguarding positioning of temples in the world. One of which allows you to specify the exact region (512x512) position about which the quad-hut should generate, without affecting the performance. For example:
./find_quadhut 0 0
will start a search with a regional positioning around the origin. (Actually the huts will be positioned in regions (-1,-1) to (0,0) this way.)
To my knowlege, as of the time of writing, this is fastest single-thread quad-hut-finder out there. However, note that the current implementation of the biome finding optimisations causes the finder to miss some seeds (< 2%) in favour for speed.
Finding Compact Biome Seeds
This finder searches for seeds that contain all major biome types within 1024 blocks of the origin. These seeds are very rare and it might take a moment for the finder to yield any. The commandline arguments are:
./find_compactbiomes [starting_seed] [end_seed] [threads]
Cool Seeds
All Biomes near Origin
Below is a list of some very rare seeds that have all the interesing biomes in very close proximity to the origin, offering some unique scenery. TIP: If you are creating a new world you can use the Custom World Generation setting to reduce the biome size by a factor of up to 4, which puts all the biomes even closer together.

Lots of Witch Huts
Four is the maximum number of huts that can generate close enough together to be operated by a single player. However, if you have a server, or you just want multiple witch farms in your world, then you can consider seeds with more than one multi-huts. Unfortunately, seeds that have two quad-huts are extremely rare, and it turns out that the closest distance between any two perfect quad-huts is around 269000 blocks. Instead we can look for seeds with less constraints, such as having triple witch huts in proximity to the origin.
For seeds that have a quad-hut with 2 additional tri-huts, I present to you all seeds that have the multi-huts in the closest proximity to spawn. In fact there are only 6 seeds that have all of them within 40000 blocks. Luckily all of the hut coordinates are inside a swamp, giving a total of 630×3 spawning spaces for each of the seeds.
| Seed | Quad Hut | Tri Hut #1 | Tri Hut #2 |
|---|---|---|---|
| 181201211981019340 | ( 5480, 4984) | (10616, -8344) | (-23688,28520) |
| 2178171917826985089 | (-3736,-3720) | ( 1400,-17048) | (-32904,19816) |

| 3382334921639955859 | (28008, -648) | (33144,-13976) | ( -1160,22888) |
| -8386696804585992813 | (28008, -648) | (33144,-13976) | ( -1160,22888) |
| 4027541812768105332 | (-5784,-7304) | ( -648,-20632) | (-34952,16232) |
Also there exist a hand full of seeds with two imperfect quad huts that are relatively close to spawn. These huts can be up to 2 chunks further appart. Unfortunately this means that they always have some parts that are just outside the 128 block despawn radius, meaning that they will only have the efficency of about 3 huts. However, they have a much larger operation area, so you can move around while the farm in running. A list of these seeds can be found in ./seeds/imperfect_doublequadhut.md.
