Creating Look-At Target in Blender Geometry Nodes

The focus of this video lies in creating a rotation control for a laser. This simple node setup can be seen as a look at constraint which can be useful in many projects, for example pointing multiple instances toward a single target.

The key to achieving this control lies in understanding the Align Euler to Vector node. Instead of manually setting degrees for an object's rotation, this node enables us to align the object towards a specific point in 3D space.
