This triangular tessellation is an abstraction of an image and is generated through a script I wrote using the Processing programming language. I wrote the script to interpret an input image and give a resultant triangular tessellation with larger triangles representing brighter areas of the image and vice versa. After initial investigations/experiments I am very much liking the results that I have been able to produce.

Adding to this, I wrote a couple of RhinoScripts to interpret the data from Processing, recreate the triangular geometries as Rhino-native polylines, and simplify the resulting network of lines into the simplest, straightest paths for a CNC mill. I did this in order to convert this 2D representation into a 3-dimensional abstraction. The linework is milled out of a painted wooden board to create a rather intriguing relief.

Although I used a number of softwares/mediums to get the final finished product, I built the bulk of the programming in Processing.
