Grasshopper Experiments

Intermediate Rapid Prototyping Technologies. Spring 2019. David Touretzky.

My overall goal with this project was to create the impression of a hand by populating the space or surface in interesting parametric ways ways. It didn't work out quite as I hoped, but I was able to interpret the hand mesh in a couple slightly different ways.

The one to the far left is the only one I had time to clean up and print before the project was due.

This is a zip file of the Rhino, Grasshopper, and STL files: https://www.dropbox.com/s/8n6ft3dml6t3ibp/handLattice_handin.zip?dl=0

Process

At first I wanted have a single line wrap around the whole mesh. I tried to project a helix curve onto the mesh but for some reason the result was a collection of disjoint curves. So I decided to use two collections of such curves from two helixes rotated at different angles.

Lofted mesh along projected curve:

I ran into problems with printing these models out for real however.

I then tried to use Grasshopper's Cocoon plugin, but I didn't get around to printing it out.

In the end, I took the intersection of the mesh and several flat cylinders along a line.

These were a couple other experiments:
