Polygons to Edges¶
Functionality¶
Each polygon is defined by a closed chain of vertices which form the edges of the polygon. The edges of each polygon can be extracted. If a polygon is defined by a list of vertex indices (keys) as [3,5,11,23]
then automatically the edge keys can be inferred as [[3,5],[5,11],[11,23],[23,3]]
. Note here that the last key closes the edge loop and reconnects with the first key in the sequence.

Parameters¶
Unique Edges : When active the node will remove the doubled edges
Advanced Parameters¶
In the N-Panel (and on the right-click menu) you can find:
Output NumPy: Get NumPy arrays in stead of regular lists (makes the node faster)
