glBSP - The GL-Node Builder

  ABOUT     news     download     specs  


glBSP is a node builder specially designed for OpenGL ports of the DOOM game engine.  It adheres to the "GL-Nodes Specification", which means it adds some new special lumps to a WAD file that makes it easy and fast for an OpenGL DOOM engine to compute the polygons needed for drawing the levels.

There are many DOOM ports that understand the GL-Nodes which glBSP creates, including: EDGE, the Doomsday engine (JDOOM), PrBoom, Legacy 2.0, Vavoom, Doom3D and ZDoomGL.  See the links below.


The current version is 2.24, released on 26th July 2007.  Both the command-line version (glbsp) and the windowing version (glBSPX) are considered stable now.
