Laser cut 3D sculptures remind us of an old Playstation

[Paul] a.k.a. [VoidFraction] put up the source and documentation for his sculptures made with laser cut polygons.

For computing his triangles, [Paul] developed LcAgl, an algorithm that transforms a 3D model into the AutoCAD file needed to cut a whole bunch of triangles and connectors. This file was shot over to a laser cutter and after a confusing assembly, … Read the rest

Simulated annealing

annealing

Here’s an update on our earlier post about genetic programming. Altered Qualia has posted a new implementation of [Ron Alsing]‘s idea. It starts with 50 polygons and then randomly changes one parameter with each optimization step. If the the change results in fewer differences from the target image, it’s kept as the new best DNA. This search method is … Read the rest
