Is it possible to raycast or perform other intersection-tests against geometry that is points or lines? (not triangles or volumes)
I'm looking to create a 3d visualization tool, so the geometry doesn't need actual physics collision, but I need the user to be able to mouse-pick to select various shapes, some of which are just lines or point-sets. But the points and lines can change dynamically.
I know how to do this in straight OpenGL or D3D, but I don't see how to do this in Godot.
Thanks in advance,
Lee
