ET-XreaL Continues Moving Towards Better Graphics
While hope may be lost with Urban Terror HD, it seems the XreaL version of Enemy Territory is moving along nicely.
XreaL is an open-source game engine that Phoronix was the first to report on in April of 2009. The lead developer of XreaL claims it to be the most advanced open-source game engine. It's code is based upon the open-source id Tech 3 engine , but it's been rewritten to provide a pure GLSL (GL Shading Language) renderer, is written against the OpenGL ES 2.0 specification, emerging OpenGL 3.x support, a true 64-bit HDR rendering pipeline, shadow mapping, light interaction system, and many other visual features lacking from nearly all open-source game engines. XreaL is not up to the same level as say the Unigine engine, but it's graphics back in 2009 were great and on the same level -- if not better -- than Nexuiz, which could be considered the open-source game with the most compelling graphics capabilities.
