I want to be able to duplicate flat geometry, then offset and scale it to create an outline effect behind it when viewed in orthographic view. This is what I have so far:
The shape on the left is created with the geometry node setup shown beneath it. The shape on the right was created manually, and is the effect I am aiming for.
The problem is that the Scale Elements node scales from a central point, which works fine for symmetrical shapes which can have a central origin point. However, when you try to apply this to an irregular shape, you end up with uneven edges. I would like to be able to scale the shape behind it in a way that makes an even border around the whole shape.
I have already tried Higgsas’ Inset Faces node group, but it doesn’t work for this since it insets every single face individually, instead of adding a border around the whole mesh.
The idea is something conceptually similar to the Inflate tool (Alt + S) in Edit Mode, where each vertex is pushed out in the direction of it’s normal, but this method doesn’t work for a 2D face since the normals all point in the same direction. If there is a way to rotate the normals of each point outwards, then that might work, but I haven’t figured out a node setup for that, and I’m not 100% sure that would create an even border.
Any ideas how to accomplish this?
