Creating a HyperNURBS Object with GH

Hi Everyone,

I'm wondering this issue for quite some time, and I hope to find an answer between you experts here..

I'm looking for a definition or a component within GH that will enable "smoothing" shapes, like the HyperNurbs option in C4D.

Does any of you have any idea what is the best way to achieve a similar operation in GH?

Looking forward for your answers,

LIM

What C4D calls HyperNurbs is usually referred as mesh subdivision or sub-d. Install the Weaverbird plugin for Grasshopper and use the Catmull-Clark or Loop subdivision components.

Hi Vicente,

Thanks for you replay.

It's really helpful.

Are you familiar with any basic tuts on how to use Weaverbird?

Thanks,

Lim

No i'm not, but there's not much to it. A new tab called WB should appear in the Grasshopper ribbon with new components. At the far right you'll find the subdivision components. Just connect a mesh output to a Catmull-Clark or Loop subdivision component. Quads usually work better with the former and triangles with the latter, but i suggest just to play with them for a bit and see what they do.

There are specific Wb components for smoothing mesh. David also just added one on the regular Mesh menu.

Hi Taz,

Thank you! That's great help!

The "smooth mesh" component has the same effect as the _smooth command in Rhino, and, as the WB smoothing components, does not increase face count and are not subdivision components. Only the subdivision components create the same effect as C4D's HyperNurbs function.

Good point! Obviously not sub-d if the face count doesn't change.
