Sorry to here you can't open the file what version of rhino and GH are you you using, can you post up a screen capture of the error message when you try and open it in GH.

The file maps the tri-grid to the surface and extrudes these triangles to 3 different heights.

Hello,

We actually used dynamics for this project (using Nucleus/Maya, but I do not see any reason why Kangaroo shouldn't do the job either). Here's a small video showing the process:

And a paper which features the project and some more in-depth explanations:

Hope that helps shed some light on it :)

thanks!

Afraid not. But I would encourage you to check out the references in the paper I linked to. In particular this one: http://www.autodeskresearch.com/pdf/CF09-Physics-based%20Generative... (Which I believe Daniel Piker (Kangaroo), might also have mentioned on the Grasshopper forums somewhere).

Hi Anders!

Here's some more documentation for those interested in seeing how GH was was part of the process...

Hi! No equilateral and no 3 diferent highs :( just another aproach with your surface, the module has 0.74-0.80 all of them. i will try to introduce only 3 highs, now thre are random values, and i think will be better if the extruded high (move) were based in a diferent angles not in the normal to every surface . ;)

Thanks for the screen captures. The reason your unable to open anyone's files is your running a much older version of GH 0.8.004 to be exact.

As your running Rhino V4 SR9 you should download and install the latest Grasshopper(0.8.0063) from the link below with no problems. That should let you open all the files we have posted for you.
