anselm / openglribbon.java
Created December 13, 2011 22:17
A snippet of code to draw opengl ribbons given a series of connected line segments
// Note that I wrote this in java in Processing - paste this GIST into processing to see it in action.
// It is not the most elegant thing ever but it does deal with end caps and ribbon loops and the like.
// If you port this over to say objective-c / opengl / c etc - you may need to deal with polygon direction
// here is a snapshot of it running : http://www.flickr.com/photos/anselmhook/6507471719/in/photostream

anselm / TCP_Client_Server_
Created June 20, 2014 18:08
C# TCP Client Server TcpListener NetworkStream UDP
/*
Some scratch code for testing a variety of patterns of client server connection.
I needed to send data from an android phone to a macbook via USB and I happened to be using C# under Unity 3D. Some of the problems I ran into included:
- co-routines under unity were not fully exhausting the tcp buffers fast enough i think; even when I aggressively polled until they were empty...
- kept running into a curious bug where when the android device overheated that there would be a huge latency in traffic from the android device to the desktop.
