I wan't to orientate my cylinders along the blue arrows. I am thinking that normals are the solution but since I am new to Geonodes in Blender I dont know how. Can you help me?
Unfortunately, due to the structure of your Geometry Nodes, it is not entirely clear to me what exactly your goal is, so I'll try to provide an answer here based on a guess that might help you.
There are a lot of questions/answers that deal exactly with this topic, but in principle require the understanding of the node
Align Euler to Vector.
Hence a try:
I assume you want to instantiate cylinders circularly on multiple planes.
- Create a cylinder first.
- Move it by half of its height on the Z-axis. Thus its rotation center is around the lower end.
- Then instantiate it along the points of a circle.
- Use the input node
Normalon the input Vector of the node
Align Euler to Vectorto create a Rotation for the objects to be instantiated. Simply put, this node uses the normals of the points, and in this case aligns the Z-axis of the object to be instantiated along them.
- Then instantiate this geometry again along the points of a line.
Maybe this answer will help you a bit. I just didn't want to leave the question unanswered.
