algorithmic modeling for Rhino
Weaverbird - mesh topologies in Grasshopper
Topologies in Grasshopper
Weaverbird is a plug-in for topological transformations in Rhino 4.0 and Grasshopper 0.8. It helps smoothing, modifying and preparing meshes for rapid manufacturing technologies from within Grasshopper.
Contains these commands:
- Catmull-Clark smoothing
- Split mesh into Quads
- Loop smoothing
- Split mesh with inner face
- Sierpinsky Triangles subdivision
- Frame
- Sierpinsky Carpet
- Window
- more...

Hi Arthur, there is a problem in the Grasshopper installer if you go back from 0.7 to 0.6. The rh_common folder is not deleted and Grasshopper tries to load it. If you are currently using Gh 0.6, please manually delete the folder rh_common from "C:\Program Files\Rhinoceros 4.0\Plugins\Grasshopper". The error should disappear. Please let me know if this solves it,
- Giulio

Hi Se, I see! Did you install the component to the default locations?
If not, could you please try uninstalling it and re-installing?
Thanks, I'll pm you, Giulio

Thanks Giulio,
It has a little trouble with
maybe load WeaverBird problem...

Arthur - you might want to look at these papers:

Thanks Giulio,
I am trying to reproduce a giant LillyPad using weaverbird but since it s a complicated solid i think it's harder to compute. Would you have any ideas as to how i could subdivide such a polysurface?

Hi Arthur, Loop subdivision creates that special vertex (it's how it works) when four edges meet at the same vertex. Catmull-Clark subdivision works better for quad meshes (like a box). There are other subdivision schemes, like Sqrt(3), that do not have this problem, but have other limitations. Hope it helps, - Giulio

Hi Giulio,
I was trying to make subdivide a boxy mesh with weaverbird and i always get a strange edge (image below) which i wish i wouldn't have.
Would there be a special tool i could use to subdivide with no edges ?
many thanks,
Arthur
