Freeform reciprocal frame system

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.

Thanks for your reply. Yeah, of course I don't look for identical triangles, I just would like the mesh to be symmetrical as the surface is. What do you meen with rational geometry?
