Generative + cnc.
An experiment with Nodebox output to a cnc laser cutter.
The idea was to make a fossile with a (heavy) laser cutter and use Nodebox to generate the model in.
The centipede-like structure is a generative design made by using mainly core nodes and functionality. The math behind the skeleton was done over an additional python file that renders Voronoi segmentation. The skeleton itself is the medial axis path derived from that segmentation.
The cnc laser cutter (we could use one at a local fab lab) was set to engraving and expects a png file. The variation in graycolor is translated to depth by the machine.
Here is a step by step tutorial on instructables on creating the centipede. You can download all files at the end of the last step.
