Mesh or surface from branch structure

Hi guys,

I have attached the relevant rhino file to this post. Basically I have a branching structure and I need to create a surface around the curves so that they become branches. It would be great if the branches became thicker the more branches join, as in a typical branching structure.

I was thinking that some sort of 'marching cubes' algorithm could work but really not sure. The bit I'm having difficulty figuring out is how to get a smooth intersection between surfaces when the branches converge.

Any help would be much appreciated!

cheers,

Phill

dear systemig,

i'm sure that you can tell me how can i create something similiar
like the possibility in mayas hair-system. i've found something
for grasshopper, but no satisfactory answer until now.

the project by shampoo illustrate very well,
what i mean with maya hair system.

I think the Kangaroo bundling should work well enough for that (see in post Phill linked).

the question was too easy! (:

dear phill,

would you explain how you did the curves,
or share your definition?

look at this:

thanks in advance

Hi Rassul,

I actually used Processing to create my 'optimal paths'. The workflow is pretty straightforward, I just modelled a ruled geometry in grasshopper (hyperbole of revolution) and then exported it into processing via python which exported all the info as a text file. Processing creates particles and springs where the lines were in grasshopper and then does its attraction, physics thing. From processing you export it as a dxf and import it into rhino.

have you seen this post?......http://www.grasshopper3d.com/forum/topics/grid-deformation-in-respo...

yeah the shampoo project from the drl is pretty cool, been using that as a reference myself.

cheers,

Phill

dear phill,

many thanks for the answer and refer.

it sounds interesting what you do...

perhaps even a question:

do you know how a "3d bundling/threads" works?

something like this:
