minecraft-measurement-mod

The Minecraft Measurement Mod allows the terrain to be measured from the player's perspective. Custom LiDAR and IMU sensors can be simulated. Cave-survey like measurements with edges and vertices are also possible. The measurement data is saved externally as CSV.

Setup

The recommended Minecraft version is 1.20.*.

1. Download and install Minecraft Forge
2. Download a MMM-release that fits your Minecraft version
3. Put the .jar file of the Minecraft Measurement Mod in your mods folder in .minecraft (usually located here: C:\Users\<userName>\AppData\Roaming\.minecraft)
4. Run the game

Example 2/2: Survey Measurement

This example shows a survey with multiple vertices and edges. The data is being saved into a edges.csv and a vertices.csv file. Each vertex has an ID and a position. Each edge has an ID, a start vertex and an end vertex. By changing the head of the survey, one vertex can be connected to multiple edges.
