ZDoomGL V1.22 gl(0.4) [29/03/99]
--------------------------------

ZDoomGL is an OpenGL port of ZDoom.
ZDoom  (http://zdoom.notgod.com) is a Win32 port of Doom by Randy Heit (rheit@iastate.edu).
ZDoomGL compiles with Microsoft Visual C V5.0 compiler.
Minimal requirements are a Pentium & 32Mb of memory.
A 3D accelerated card is needed (OpenGL compatible).
It runs fine on a P200 with a voodoo1 3dfx card.

What's new in V0.4:
-------------------
- You can now add dynamic ligthing to any state of any items (like emit light when a monster fire).
- A lot of optimisations (especially items rendering & dynamic lighting 2).
- 3Dfx MiniGL driver support. If if you have a low end machine with a 3Dfx card (like me), you should use it, it is a lot faster. Remaining problems with MiniGL are MD2 & Mirrors.
- External camera bug fixed.
- "Fog on transparent walls" bug fixed.
- FOV support.
- End episode / intermission screens crashs fixed (except end of episode 3 for Doom 1).

ZDoomGL has been successfully tested on (with a decent framerate):
 P200     + voodoo1 (Win98)                [V0.4]
 PIII500  + TNT2 (WinNT)                   [V0.3]
 PII450   + GeForce 256 (Win98)            [V0.2] 
 PII450   + voodoo2 (Win98)                [V0.2]
 PII450   + S3 Savage 4 (Win98)            [V0.06] 
 PII300   + G200                           [V0.02]

Important note:
---------------
You need to install ZDoom before running ZDoomGL.

Quick Start:
------------
Put ZDoomGL.exe in your doom directory (shareware V1.9, Doom V1.9 or Doom II V1.9).
3D PCI cards < 8Mb users: launch VOODOO1.BAT
3D PCI cards > 8Mb users: launch VOODOO2.BAT
AGP users: simply launch ZDoomGL.exe.
Please, note that all 3Dfx cards (except voodoo1) should use the VOODOO2.BAT file.
(3Dfx cards don't support AGP memory texturing).

MD2 support:
++++++++++++
Please read the MD2.TXT file.
Note that the md2.ini provided with ZDoomGL is for Edmundo Bordeu's MD2 pack. If you want to use YPOD models rename md2-YPOD.ini to md2.ini.
The MD2 skies work only with Doom II (and DoomII PWADs with no custom sky). You need to download the MD2 files from www.doomworld.com/doomgl.
If you don't have the MD2 HUD weapons from the Q2 Generation mod, just use the md2.ini from the last Edmundo's MD2 pack.
(You can find the "Generations" mod here: http://fileplanet.com/index.asp?search=generation),
