algorithmic modeling for Rhino

I thought this group sounded like a fun idea, so I thought I would suggest one based on something I was looking at earlier in the week.  

The challenge:

To find the medial axis of a 2d polygon in 15 native components or less without scripting.

Good luck!

Because they are the midpoint of the lines from the delaunay diagram they are equidistant from exactly two points on the perimeter, but i guess they aren't always necessarily the nearest points, so maybe its still an approximation:

Yes, I see your point.  I think you are also right about the center point / end points relationship not necessarily being the closest points...

if we keep going, eventually we will get it ;)


Very interesting analysis.

I have started a discussion here

essentially looking for the same principle applied in a 3d mesh.

Any idea very much appreciated.

Thank you,


hello! is there any way to obtain a medial axis w/in a 3D volume like this?

I am trying to extract the interior volume as an object instead of the negative of a Boolean operation.

I'm hoping to get a media axis between surfaces within this volume to then pipe/t-spline into a new object.
