BSP2MAP v0.1

bsp to map convertor.

BSP2MAP.ZIP - bsp to map convertor, exe for Win32 and src.

--------------------

this program reads bsp file, and generetes map file from it.

it is just version 0.1 and is not wery good.

my goal was not to make realy usable convertor, but just to proof that it is

possible.

still its usable for small (and maybe even medium) maps.

method used in this program is wery simple: it creates one brush

for each face found in bsp file, so resulting map file contains much

more brushes than original. so after converting big levels back to map it

contains too many brushes for QBSP to handle and for most editors to load.

there is problems with water/slime/lava brushes

also it sometimes generates "brush with duplicate plane" and "brush plane with

no normal"

its not good to create brush for each face, but its was easy (i spent

only 2 days to write this program). it must connect brushes together

and use all other information found in bsp file unfortunatly i know

nothing about BSP trees, Nodes, Leaves.

im not sure that i will continue work on this program, probably will not.

i tested it with:

start.map had 4900 brushes (4096 is max for QBSP)

dm4.map had 1800 brushes

dm5.map had 2060 brushes and i succesfully QBSPed these maps and played in

Quake.

Notice

--------------------

this program contains some functions from Carmack's QBSP (from qbsp/map.c).

to compile this program you also must to have quake utils2 (files

common/bspfile.c,

common/cmdlib.c, common/mathlib.c and corresponding .h files (which are not

included in this package))

you are free to use this program

you are free to use/modify/compile source code

you can do anything you want with it

John Carmack, for quake utils2

peoples on rgcq.editing for saying that it is absolutely impossible to

convert bsp to map, w/o them i would never wrote this program.
