Note that if your nodes disappear, you can get them back by clicking on the “Geometry Nodes” modifier in the right-hand pane: Now, we click on “New” to create a new geometry node setup: We won’t be needing the window in the upper left that shows the positions of all our vertices, so we can close that: Click on that, and choose “General -> Geometry Nodes”. If you don’t see this, look for a little down arrow near the top right corner of the top menu bar. We’ll create a new Workspace (tab) at the top of blender, which will allow us to see our geometry node setup alongside our donut: This enables all sorts of cool stuff, from the ability to dynamically generate frost or icicles on a surface, to the ability to create buildings whose height, window position, and number of floors are all procedurally controlled. Much like the nodes we’ve used so far to create texture, geometry nodes allow use to procedurally generate changes to the mesh (changes to our objects). In previous versions of the donut tutorial, “particles” were used, but “geometry nodes” are a better option in Blender 3.x. Next, we want to add some sprinkles to the donut. This file is the result of my work after following along with the steps in the YouTube video.

Just some notes I made while following along with this now-famous blender donut tutorial.
