Tetrachord Lib
by Viola-Siemens
Tetrachord Lib is a library and optimization Minecraft mod from Viola-Siemens with 31.7K downloads on the Orca catalog. It runs on Fabric, Forge and NeoForge, so it slots into a matching Minecraft profile without hand-patching anything. Tetrachord Lib is free to download and free to host on Orca: press Play and Orca launches Minecraft with Tetrachord Lib already installed, or host it on a free server to play with friends. There is no control panel and no config files to edit, and no command line to learn. Describe what you want in plain English and Orca installs Tetrachord Lib along with the loader and Minecraft version it needs, then you and your friends are playing in minutes.
A lightweight library mod that provides various data structures such as KD Trees and Segment Trees, alongside some other utilitarian functionalities.
