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.. [...]

Goldfish V4 UI panel – Encoder Rings

2014-05-19T12:29:29+00:00

The FPGA-based Goldfish is still in constant flux. I decided it needed more encoders on the frontpanel, AND some visual feedback for the value of each of the encoders. Each [...]
