Peak is a Minecraft density function library that computes coordinates.

Peak is licensed under the Mozilla Public License version 2.0. A copy of the license is included, and an FAQ regarding the license can be found here.

The current supported versions of Minecraft are 1.19 and 1.19.1, however the pack may still work on older versions.

The x and z coordinates provided are inexact, and may change for a given seed based on implementation details, so implementations are given different names. A given version of Peak is guaranteed to be compatible with any other version based on the same Minecraft version, meaning that all density functions and noises in all stable implementations will work, and give the same result, when multiple versions of Peak are loaded. The purpose of this is to make embedding Peak in a data pack safer, and to make it easier to build new implementations from other ones, while also maintaining performance. Stable implementations reside in peak:s/, while unstable ones should be in peak:exp/.

The density functions that compute the coordinates can be accessed at peak:s/<impl>/x, peak:s/<impl>/y, and peak:s/<impl>/z. With the simple (and currently only) implementation base, it would look like peak:s/base/x.

Embedding Peak into a data pack is suggested for ease of distribution, and because loading multiple data packs containing different versions of Peak should not cause any issues. The peak namespace folder in data contains an additional copy of the license, so the entire folder can just be copied into a data pack.
