ZDoomGL V1.21 gl(0.2) [02/12/99]
--------------------------------

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 V0.2
-------------------
First beta version.
- ZDoom V1.21 port.
- Support for MD2 HUD weapons: 
	The md2.ini included in this archive works with the "Generations" weapons models.
	You can find the "Generations" mod here: http://fileplanet.com/index.asp?search=generation&file=11764.
- New sky code:
	+ Method 1: the original sky code.
	+ Method 2: Inspired from the JHexen sky code (thanks to Jaakko Kernen author of JHexen).
	+ Method 3: MD2 sky (thanks to Edmundo Bordeu for the MD2 skies).
	The method 3 works only with Doom II (and DoomII PWADs with no custom sky).
	In the console: "g_bSkyMethod" 0 = Method 1 / 1 = Method 2 / 2 = Method 3.
	Please note that ZDoom specific skies (double sky, scrolling sky, etc) are not currently supported.
- Another 2-sided walls bug fixed. (some backface textures were misaligned).

ZDoomGL has been successfully tested on (with a decent framerate):
 PII300   + voodoo1 (Win98)                [V0.2]
 PIII500  + TNT2 (WinNT)                   [V0.2]
 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.
