glBSP - The GL-Node Builder

ABOUT	news	download	specs

Introduction

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.

Status

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.

Copyright

glBSP is Copyright (C) 2000-2007 Andrew Apted. It is based on 'BSP 2.3' Copyright (C) 1998 Colin Reed and Lee Killough, which was created from the basic theory stated in DEU5 (OBJECTS.C) by Raphael Quinet.
