Playing with adaptive level of detail quadtrees

2014-05-27T17:55:21+00:00

Quadtrees never fail to amuse. Source + binary (C#, Visual Studio 2012): QuadTreeImageToy Loosely based on http://devmag.org.za/2011/02/23/quadtrees-implementation/ The usual disclaimer applies: batteries not entirely included, unoptimized, it could be done cleaner.. [...]

Kezboards, umlauts and USB

2014-05-27T11:42:58+00:00

While searching for some easy-to-add USB options for the new Goldfish development, I revisisted the V-USB package. This package allows you to add USB to any small microcontroller that can [...]
