I wanted to learn geometry nodes, so I started a course called “Geometry Nodes From Scratch” from Blender Studio. Here’s how it’s going:
.
Project 1: Rock generator
Fairly simple. Done by rotating ico spheres around and using boolean mods. These four different results are created by tweaking these few settings:
.
Project 2: Rock Scattering
This project takes the rocks created in the first project and makes a system to scatter them around a plane. The deformation of the plane was also done with geometry nodes.
The density of the rocks is roughly tied to a vertex group which can be weight painted. Don’t know why I did a ‘G’.
.
Project 3: Tree Generator
I added the trunk myself using the concepts from the videos.

Conclusion
Its interesting stuff and I’ve enjoyed it so far. The theory videos took me a couple viewings to fully understand, but the projects exemplify the concepts well. It is a paid series, since you have to be subscribed to Blender Studio, but I figured I might as well throw them a few bucks since Blender is free and they’re the people developing it. There’s one more section I haven’t done yet, so I’ll post my results after I get to that one.
