Data Tree question - simplify tree so that every branch has a distinct path {A}

Ok, I've never asked a question on these forums before so any advice or help would be very much appreciated.

What I'm wondering is how can you simplify a tree structure such that every branch is renumbered by the following logic:

{0;0}  >  {0}

{1:0}  >  {1}

{1:1}  >  {2}

{1:2}  >  {3}

{2:0}  >  {4}

Any help would be great.

Thanks,

James

Hi James,

You can use the Path Mapper to achieve this. If you have Grasshopper 0.9.0062 or newer you can use the presets in the menu to automatically create this mapping:

The mapping for this is always {?????} -> {path_index}

Where the question marks represent what you actually have. If your input is {0;0}, {0;1}, {0;2}, {1:0}, {1:1} etc. then ????? will be {A;B}

David,

Thank you very much for your quick response.  That was exactly what I was after.
