Equilateral trianglar mesh with kangaroo

by SEAN TITTLE

May 25, 2016

Hello, 

I am designer attempting to apply an equilateral triangular grid onto a mesh shell (walls/ceiling).

If the overall shape gets modified as a result of the the sequence that is fine but I would like to preserve the general form.

I have been experimenting with Kangaroo the last few days and am at a bit of a loss.

Unfortunately most of the GH/Kangaroo scripts are for older versions and therefore are missing elements when I import them.

Any assistance would be greatly appreciated!

Thanks for your time.

Sean

    Try the newts Kangaroo2

    At that time of the year the new Kangaroos are
    leaving the field ... have patience!

      Sean,

      FYI, an "equilateral triangle grid" (i.e. triangles of all 60-60-60 degrees) is not possible to tile 3D over surfaces that do not conform to a very rigid set of properties.   Even the triangles you see in a geodesic dome are not equilateral (when flattened into cartesian coordinates).

      Are you looking for a mesh that *looks* equilateral?   In other words, a meshing of triangles that comes as close as possible to having equally sized and angled triangles?   Be aware that over complex surfaces like yours, the triangles will (almost certainly) not be equilateral and each one will (almost certainly) be unique.

      If that's the case, meshmachine is your best and quickest bet.   It will allow you to make a mesh that conforms to your starting geomtery, allow you to pick points and edges to constrain it to, and allow you to pick a target size for each one of your triangles.

      If you're having trouble getting it running, try doing a fresh install of Kangaroo.  Make sure you right click "properties" on the files it installs into your Grasshopper libraries folder and check "unlock".

        What you are referring to are also known as Lobel frames. There's been quite a bit of research on this topic. That might help you to better understand the modelling problems. But yes, it does indeed seem like a job for Kangaroo2 :)
