Introduction to Geometry Node Setups

Geometry node setups in Blender are a way to manipulate and control the geometry of an object using a visual node-based system. They provide a powerful and flexible way to create complex effects and transformations without having to write code.

In a geometry node setup, you work with nodes that represent different operations or functions. Each node performs a specific task, such as modifying the position, rotation, or scale of the geometry, or applying various mathematical operations.

To create a geometry node setup, you start by adding a Geometry node to your object. This node represents the input geometry that you want to manipulate. Then, you can add other nodes such as Modifiers, Deformers, or Procedural Textures, and connect them together to define the desired transformations or effects.

For example, you can use nodes to scatter objects across the surface of another object, deform geometry based on procedural noise patterns, create patterns and repetitions, or even generate complex procedural shapes.

By connecting nodes in different ways and adjusting their parameters, you can achieve a wide range of creative results. Geometry node setups provide a non-destructive workflow, meaning you can easily tweak and modify the setup at any time to refine your effects or try out different variations.
