POSITIONING PARAMETRIC DESIGN

Tri-Surf Video Demo

I have reassembled the Tri-Surf project and reprogrammed the Arduino. Click here to watch the high quality version of it on YouTube if you cannot see the embed player below.

What if we had something that could model a variety of surfaces in real-time? Tri-Surf is my attempt to do this by moving a collection of triangles to form an approximation of the surface modeled in Rhino. This previous post contains a few 3D images along with a slightly longer description.

The assembly process was far more challenging than I anticipated. There remain errors with the design due to the tolerance in the length of the string, however the current model using elastic string is much better than the original with fishing line (which may have been the worst idea ever). I also learned that you cannot run 9 servos on one 5v source if you want them all to move at the same time.

The new and very much improved version:

Design is an iterative process.
