Map curves from one shape to another

Hi all,

I'm new to grasshopper and am currently making my way through the primer. Currently I'm trying to learn by doing some small projects.

I've tried to map a simple voronoi structure from the initial rectangular to a circle, but with no success. I've tried to follow instructions from here http://www.grasshopper3d.com/forum/topics/map-voronoi-to-surface?id... which does not seem to work for my case.

Hence my question:

If I can only generate a 2d voronoi structure within a rectangle, how can I project the resulting curves/points into a different 2d shape?

Alternatively: How can I generate a voronoi structure with bounds other than a rectangle?

I've attached my surface mapping attempt.

Any hints appreciated! :)

Hi there,

I've managed to map points from outside the curve onto the curve. Unfortunately I have trouble with joining the points into a consistent list in the data tree. When I join the lists it seems that the data tree is messed up. Can anyone help please?

What I get is:

but i want is something along the yellow lines:

Can anyone point me in the right direction? This is the path that I use to pull the control points onto the curve:

Thanks for your advice!

Regards,

Florian
