Grasshopper

algorithmic modeling for Rhino

Hi guys,

Is there a way to split a list when a "new line starts" as the image below indicates in blue? The grid is not regular so "flip matrix" would not work. I have also tried using distances to dispatch but faced another issue.

Many thanks,

Arthur

You can use this.

Order of points matter.

Absolutely brilliant!! 

Thanks so much Systemiq!

Two questions if you have time: 

-How does the C# script work?


int j = 0;
DataTree <Point3d> Tree = new DataTree<Point3d>();
{GH_Path Path = new GH_Path(j);
Tree.Add(x[0], Path);}

for(int i = 1;i <= x.Count - 1;i++)
{if (x[i].DistanceTo(x[i - 1]) > dist) j++;
GH_Path Path = new GH_Path(j);
Tree.Add(x[i], Path);
}
A = Tree;

 

-Can you use this to classify the polyline cells around the points?

It simply iterates through the points in the list, if there is a "row jump" (i.e. distance to previous point is > to some preset value) the current point is added in a new branch.

You can input the cells and they will get same data structure.

Excellent ! 

Merci beaucoup, ça marche comme sur des roulettes :)

This would be such a useful GH component !
