thanks, well first I scan objects with a digital SLR and an in-browser app called 123D catch. Then I download an OBJ file and clean it up and reduce the number of faces in meshlab. Then I import the file into a custom made Processing sketch that is built using a library called He_mesh. He_mesh has all these functions like bend, twist, expand, and so on. I’ve built upon some of these to introduce Perlin noise, etc, and I’ve made my own interface so that I can trigger those functions with keyboard shortcuts and a set of sliders. I call my sketch ccc. It also algorithmically generates colour patterns and gradients. The sketch exports the models as VRML files with colours assigned to each face. To prepare these objects for 3D printing I use Magics which automatically checks the file for errors and can hollow out a solid. I then send these to print via Shapeways. The whole process can take 2 - 5 hours which is not bad compared to traditional approaches to sculpture.
