Since quite some time I have an interest in GIS and rendering, and after experimenting with the two separately I decided to finally try and render geographical data from OpenStreetMap in 3D, focusing on a small scale never bigger than a city.

In this article I will go through the process of generating a triangle mesh from a building shape, rendering and exporting it in a format suitable for Blender or game engines like Godot. I’m not an expert in the field but I’m sure there are people out there facing the same issues that may enjoy reading this.
