PQ Circular mesh in Kangaroo

Planar Quadrilateral meshes (and particularly the special cases of Circular and Conical meshes) have numerous advantages for architecture and fabrication (see the work of Bobenko or Pottmann for details).

I am developing ways of optimizing meshes within Kangaroo in a way that allows the user to interact during the process. A balance can be set between factors such as how tightly the mesh is pulled onto the NURBS surface, planarity, panel size etc.
Because they are integrated directly into the physics engine it is possible to combine these geometric constraints with any of the other force-based form finding methods I have shown earlier.

It's time to move beyond post-rationalization of 'free-form' surfaces. 'Construction-aware-design' here we come!

It is a great job. I am very interested in what are you doing in particular PQ meshes.

I would be appreciated it if you could share the GH file of this example.

Thank you very much,

Amir

Comment by Ioanna Symeonidou on October 4, 2010 at 1:05pm: Great work Daniel, as always! And yeah....we all learnt a lot at the AAG.
I would love to see this definition with the circles, today i was asked to do something similar at work and didn't have a clue (!) i should start playing with kangaroo...
Cheers!

Comment by Daniel Piker on October 4, 2010 at 12:48pm: Rodrigo - I should say, I picked up that phrase construction aware design at the recent AAG (I think from Jacob Riiber and Martin Tamke's presentation), and thought it nailed a general idea that seemed to be very much in the air (of course there was a fair amount of the old post-rationalization stuff too, but I sensed a growing shift). Also Embedded Rationality (from Robert Aish) is another nice label for it.
And yes - I'm a big fan of Lorenz's work.

Comment by Daniel Piker on October 4, 2010 at 9:15am: Thanks all. I'll test it out on a bigger mesh. If someone has a nice NURBS surface to use as a test case please let me know!
