# Procedural fantasy city creation using Geometry Nodes in Blender

The evolution of Geometry Nodes in Blender has enabled the creation of increasingly larger procedural projects and setups over the past year. This talk focuses on the construction of a fantasy city from basic building blocks.

Starting with a simple idea, a city layout and terrain are generated, buildings are grown from the ground up, populated with props and shaded procedurally.

Geometry Nodes is a system for modifying the geometry of an object with node-based operations. It can be accessed by adding a Geometry Nodes Modifier.

The geometry node tree connected to a modifier is a Node Group. The geometry from the state before the modifier (the original geometry or the result of the previous modifier) will be passed to the Group Input node. Then the node group can operate on the geometry and pass an output to the Group Output node, where it will be passed to the next modifier.

Geometry nodes can modify different types of geometry: Meshes Curves Point Clouds Volumes Instances
