Geometry Nodes – make an object follow a curve
We can make a mesh move along a curve in Blender using Geometry Nodes. Let’s take a simple example of how to do this.

Mapping node for Geometry Nodes
The Mapping node does not exist in Blender Geometry Nodes by default. However, we can build it ourselves.
Accessing custom attributes created in Geometry Nodes
With Geometry Nodes in Blender is easy to create additional custom attributes for objects and transfer the necessary data to them. However, there is no direct access to such created attributes.

How to show parameters from Geometry Nodes inputs on a custom UI panel
Input parameters from Blender Geometry Nodes are automatically placed on the “Geometry Nodes” modifier panel in the “Properties” window on the modifier tab. However, this tab is not always open, and it is not always convenient to switch to it to adjust values. For quick access to the input parameters of Geometry Nodes, we can duplicate them on the custom panel in the 3D Viewport window.

Delete Geometry Node
Geometry Nodes has a node that allows us to remove required vertices from a mesh. This is the “Delete Geometry” node.
Using UV coordinates for working with mesh geometry
With the coordinates of the UV, we can manipulate not only materials but also the geometry of the mesh itself. We can connect the UV coordinates with the mesh geometry using “Geometry Nodes” in Blender.

Displacement with Geometry Nodes
Let’s look at how we can use displacement with the “Geometry Nodes” in Blender.
First, add a cylinder (with the 0.1 diameters, without upper and lower closing polygons) to the scene: shift+a – Mesh – Cylinder.
Switch to edit mode (tab) and add edges to make the uniform grid: ctrl+r – 100 – Enter.
