Freeform reciprocal frame system

by Elena

mesh%20machine.ghHi! I'm new to kangaroo, so sorry for probably lame question.

I'm trying to do something like this

http://www.parametricism.co.uk/blog/portfolio/freeform-reciprocal-f...

that is a workshop in Salerno 2013 about Reciprocal Frames with Daniel Picker and Gennaro Senatore. 

I've strarted from a plane and symmetrical mesh, and I triangulated it using Mesh Machine (target lenght = 1). Then I apllied the particle spring method of Kangaroo in order to find a funicular form. 

Now I would to obtain a neat triangular mesh (target lenght 3-4) that would be "regular" and symmetrical. Using MeshMachine I obtained a mesh that is not symmetrical.

Any advices?

Thamks you in advance

    As soon as you use MeshMachine, you're not going to get symmetry.

    You could try setting a target edge length using K2, whilst pulling nodes back to a surface. If you get three lengths the same, you've got an equilateral triangle. You can't tessellate a freeform shape with identical equilateral triangles though of course.

    However, it sounds like you might be best using some subdivision tools (weaverbird or similar) starting from some rational geometry.
