GitHub Blog Highlights Open-Source Project That Turns Real-World

What happened

Louis Erbkamm created the open-source project Arnis, which transforms real-world locations into Minecraft worlds. The project has reached nearly 900,000 downloads since its launch in 2022.

Arnis queries OpenStreetMap for mapped elements to generate Minecraft worlds, but cannot place elements not mapped. For detailed structures not described in maps, such as the Statue of Liberty, Arnis converts 3D models into Minecraft blocks.

Why it matters

The project has been used in schools as an educational tool, where teachers generate city or park areas for students to improve. Arnis has expanded its capabilities beyond Earth, including the Moon and Mars, showing its potential for broader applications.

Key details

The project has attracted about 70 contributors who have helped translate it into 20 languages and developed major features. Louis Erbkamm developed the first prototype of Arnis in two weeks while on a break from school.

The initial version of Arnis was written in Python and relied only on OpenStreetMap data. Louis chose Arnis, a small town in Germany, as the test location due to its detailed features like buildings, streets, and water.
