I want to to do a 3 fingers grip with Geometry Nodes. Every finger is a curve composed of 4 vertex.
With a variable of the group input named 'Angle' I need to increase the natural angle of each couple of edges (alpha and beta).
I try the GN 'Set Curve Tilt' but I don't know how tell it the direction of the rotation.
My main Geometry Nodes
My Geometry Nodes 'GN finger'
Any idea how to do it?
