How can i sort a list of Points!

hi,

i have a number of points.

i want to put them in multiple (list) groups.

if the groups are build,

then try to calculate the closest point

to the midpoint of the particular group.

hope to get an answer!

thanks

Not sure if this is what you were after, but I've had a go at your definition and done so that it maintains the flow of multiple objects through the components and keeps each set of geometry together to produce the results you were after. In the image below you can see the user defined variables for 3 sets of geometry. If you what to know more about the definition let me know.

dear danny,

i have try to work with your definition,
but it seems to me that I didn´t understand
your definition correctly, because I´m not able
to build a rekursiv tiling on it.
if you could help me one more time,
I really would appreciate it!

thanks a lot.

Hi Rassul,

Straight Of I can see your problem. In order to let a definition work independently for multiple inputs you cannot use either a Flatten Component or a Flattening Input Utility. It has to be managed by another way that keeps the multi level structure intact. This normally takes the form of the Pathmapper Component or some other Path management components.

I'll have a look and see what needs to be done with this case.

Hi Rassul,

I've added a C# Script written by Daniel Davis called "Compare every item in a list" component, available from here: (thanks to Andrew Heumann for the heads up) http://parametricmodel.com/Compareeveryiteminalist/38.html

This has gotten rid of your duplicate points problem from weeks ago. What it does is compares the first item with every other item and the second with every item except the first and so on.

Apart from the Pathmappers the other addition I've done is to automatically generate the boundary curve from the furthest points out on the "spokes". In order to do this though you need to order them around the centre. See definition for method.
