zdbsp

node builder library for OpenGL-based Doom-style games

zdbsp is a node builder specially designed to be used with OpenGL ports of the DOOM game engine. It adheres to the "GL-Friendly Nodes" specification, which means it adds some new special nodes to a WAD file that makes it very easy (and fast!) for an OpenGL DOOM engine to compute the polygons needed for drawing the levels.
