I tried doing this type of effect, here’s my feedback:
- I couldn’t use fields, because it was just missing nodes and attributes that I would have wanted to manipulate
- I wanted to use boolean operations, to clip the lines onto the mesh, but that wasn’t possible (I think), so I had to do raycasts (which aren’t available in fields yet)
- There is no way to smooth the normals of geometry generated in geo nodes, not even by trying to set the
normalattribute (I believe?!) - Boolean values are only being exposed as a float on the modifier
- Start- and end position modes would be a nice addition to the grid node
- That a geometry nodes setup is automatically available inside of other geo nodes setups as a node group is sooo good! I miss this all the time with shading nodes, so it’s great to see this done right in geo nodes.
- The performance is pretty good imo
- I only had to do very little attribute stuff
