algorithmic modeling for Rhino

Transpose list

Posted the below question on the grasshopper google group.
Does anybody have a tip on how to write this little script?
Any references to C# for grasshopper?!

The best way is to use a C# or a VB component to transpose these
lists. I think in C# you can use transpose directly. You can ask this
on the VB/C# forum on our new website, www.grasshopper3d.com

Tonsgaard,

is your point list multidimensional (a datatree)?

You mean something like this?

This example divides several curves into points, then rearranges this lists into a new set of lists where one contains first point of all the curves, another contains the second point of all the curves, etc.

Yup... exactly like this.

(it is multidimensional as all lines are divided in one go)

any way I could get that script for reference?!

It's not a script, it's done entirely out of components. You should be able to reproduce it from the screenshot. I think the only hidden bits are that the input list of the 'list item' component is flattened out and in the series components +1 is added to the number '4' from the text panel since when you divide a curve in 4 parts it results in 5 points.

There's a discussion about this in the old forum:

Obviously not script.. definition then.
I recreated it and it works... thanks a lot mate!! :-)

for developers: maybe a transpose list component would be good to have!?!
