ZDoomGL (v1)

ZDoomGL is an OpenGL port of ZDoom, maintained by Tim "Timmie" Stump. Originally it was developed by Michaël "Kokak" Ryssen, but once he got a job working at Ubisoft, development on the port slowed considerably (and eventually stopped). In 2003, Timmie picked up development, and rewrote the port from scratch to be up to date with what was, at the time, the latest version of ZDoom. The latest official release, 0.81, was released on August 7, 2005.

As of Feb 13th, 2006, Timmie has been working on ZDoomGL v2, which is another rewrite of the engine. [1 ] As of 2010 development on ZDoomGL appears to have stalled.
