Thank you very much!!! It was really helpful!! I'm just having some trouble, because in one of the skins it doesn't work, and I think it is because of the planes I'm using..

 

Hope you can help me again! =)

Have a lok at the ghx.

 

The pathmapper are not needed, but looks better this way:-)

The Join does not work because you have a different amount of curves (param shows 111 and 114 branches), but you can still ues it. Grasshopper ignores it.

wich surface I have to set in S & T?

 

thanks a lot

The Logic is:

 

create a voronoi in plane (this is S-Base Srf)

then map onto a curved Srf (this is T- Targed Srf)

ok,....but it's my screenshot!

 

I want to have that voronoi on each surface (GREEN with red dot)

 

I have only that surface and a red box (the box that I set with SET ONE BOX for obtain the voronoi)

 

and now?

 

thanks alot

First thing I would do is decompose your Pts. And set all y values to the same one.

 

then select the face the Pts are in (explodeBrep-output F- by item)

 

Have a look at my file above. at the bottom there is exatcly what I describe (besides the decompose)

 

Problem is the green Srf are not rectengular. What are you up to? that the voronoi is completly inseide each face or somehow?

well,

 

i would to connect a voronoi on each face (the green ) and I don't mean each face like a unique face....

Ok,

 

I would do it like this:

- Create a bounding sphere

- search in the forum for -voronoi sphere-

- create the voronoi onto the sphere

- project the voronoic crvs onto the srf (brep)

 

how about this?

Best Regards

i'm doin' the same thing but projecting on every surface one voronoi curve...

 

can I show you a brand new discussion that I opened for obtain one thing?
