algorithmic modeling for Rhino

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!

Hi Daniel,

Super interesting work. I'm curious if there is a way to deform the surface at points within the circles which could vary the diameter with your spring-particle solver? I'm thinking this could allow "pressure" to be determined at certain points given a certain weft-warp tension.

Hi Daniel,

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,

Hi Daniel, is this tool good enough for a beta release now?? I'd like to use it very much. thanks..

Thanks man!

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...

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.

i can finally stop reading pottman's papers and books :) great job and looking forward to the next release! eta?
