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.

Examples

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 the 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.

Seed	Notable biomes within 250 blocks of spawn	Remarks
2458028242930	Ocean, Plains, Forest, Taiga, Swampland, Ice Plains, Roofed Forest, Cold Taiga, Mega Taiga, Sunflower Plains, Ice Spikes	Decently sized Mushroom Island

Lots of Witch Huts

No more than four huts 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-hut.

For seeds that have a quad-hut with 2 additional tri-huts, I present to you (possibly all) seeds that have the multi-huts in the closest proximity to spawn. These seeds have one quad-hut and 2 tri-huts within 40000 blocks.
