Can Grasshopper produce the organic shapes of a tree trunk?

[bieleckianthony]

Hello all,

After watching Grasshopper’s introductory videos on https://www.grasshopper3d.com/page/tutorials-1, I’m still unsure if Grasshopper can (or should) be used for what I want to do. I’m trying to create organic looking trees (just trunk and branches, no leaves). So far I’ve been able to create reasonable approximations to what I want in Rhino simply by drawing curves and using the Pipe command. What I’d like to do now is extract surfaces from the pipes I’ve created and then slightly move every control point of those surfaces so that they’re not so uniformly round. Is this something Rhino can help me do and, if so, could you point me towards the functions I should learn about?

Thank you for your time.

Skeleton fattener + mesh cage morph

Hi everyone, Here is a first prototype of 2 new tools (as a .gha plugin), one for thickening skeletons into closed quad meshes, and one for morphing geometry with a mesh cage. Fattener.gha (27 KB) and some notes on how to use it here. Please bear in mind this is just an alpha version - no promises how well it will work. (This is following on from some of the earlier discussion in this thread: Creating smooth meshes from pipes, like tsPipe had in T-Splines? - #8 by DanielPiker) Thanks to a…

Check this you will need to apply some displacement on mesh

What scanner did you use for this? And what is the purpose for scanning trees?

[martinsiegrist]

Used my Artec Leo.

So far, scanning trees for no specific reason other than documenting weird and wonderful natural creations.

This is exactly what I was looking for! Thank you!!
