Topologizer/Network CleanUp

To complement the recent Exoskeleton wireframe thickening tool by David Stasiuk and myself,

I am also sharing this component for cleaning up messy wireframes or line networks.

You provide it with any list of lines and it turns them into a clean directed graph or network.

So it :

-Snaps together nearby points

-Removes duplicates, Overlapping lines and stray segments

-Splits lines at crossings and creates new nodes

-Keeps an optional set of input points fixed

It also outputs the topology information of the network, saying what connects to what:

For each point:

-A list of indexes for all the other points to which it is connected by a line

-A list of indexes of the lines which end at that point

-A list of indexes of the lines which start at that point

For each line:

-The index of its start point

-The index of its end point

and also, the simplified graph - with all nodes of valence 2 collapsed.

appears under the Mesh>Triangulation tab

mr piker does it again. merry christmas.

Here's an example of how it can be used with Kangaroo. Connected lines are trying to align/bundle near the nodes. The topology information allows us to set the interaction only between the relevant segments instead of all-with-all, speeding things up significantly.
