libglbsp-dev - 2.24-8+b1 main

glBSP 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.
.
There are many DOOM ports that understand the GL Nodes which glBSP creates,
including EDGE, the Doomsday engine (JDOOM), Doom3D, PrBoom, and Vavoom.
