GLHexen V0.9 [18/09/99]
-----------------------

GLHexen is an OpenGL port of Hexen for Win32.
GLHexen compiles with Microsoft Visual C V4.0 & V5.0 compilers.
Minimal requirements are a Pentium & 32Mb of memory.
For fast rendering, a 3D accelerated card is needed (OpenGL compatible).
It runs fine on a P200 with a voodoo1 3dfx card.

GLHexen only works with Hexen V1.1. (http://www.raven-games.com/kokak/hexn11rp.exe)

What's new in Version 0.9:
--------------------------
- Clipping problems fixed (thanks to Thierry Van Elsuwe, author of the Doom Legacy GL project, for the tips).
 in hexenrc.cfg:
	clippingquality	0, 1 or 2: 0 is the faster solution (lots of polygons missing)
							   1 is the default solution (some polygons missing).
							   2 is the slower solution (no polygon missing).
- PWADs compatibility:
	+ Tesselation errors now generates a warning instead of a fatal error, when you use a PWAD. Certainly, there will be holes
	in this sector. So you should edit it (removing the useless linedefs or adding the missing linedefs).
	+ Textures larger than 256x256 should now be visible on the 3Dfx cards.
- Polyobjects / sectors not updated when you teleport to an already visited map fixed.
- Spikes now raise/sink normally.
- "Always run" key added (key_alwaysrun in hexenrc.cfg).

GLHexen has been successfully tested on (with a decent framerate):
 P200     + voodoo1 (Win95)                [V0.9]
 PII450   + voodoo2 (Win98)                [V0.8]
 P233 MMX, 64mb RAM, Voodoo2, Win98 [V0.8]
 K6-2/300 + Riva TNT (Win98)               [V0.6]
 PII300   + 3DFX Voodoo 3 2000             [V0.6]
 PII300   + ATI Rage Pro (WinNT)           [V0.1]		(transparent sprites are invisible)
 PII266   + Riva TNT (Win98)               [V0.08]
 PII266   + S3 Savage 4 (Win98)            [V0.08]
 PII400   + voodoo2 (Win98)                [V0.08]

Note for 3Dfx users:
--------------------
Here how to install OpenGL beta 2.1 drivers from 3Dfx:
1- Download from: http://www.3dfx.com/view.asp?IOID=26
2- Run opengl2.exe and uncompress it in a temp directory.
3- Copy 3dfxopengl.dll into your Doom directory.
4- Rename it into opengl32.dll.
Similar procedure for MiniGL & Quake3 drivers.

Quick Start:
------------
Put GLHexen.exe in your Hexen directory.
3D PCI cards < 8Mb users: launch VOODOO1.BAT
3D PCI cards > 8Mb users: launch VOODOO2.BAT
AGP users: launch AGP.BAT

Important note:
+++++++++++++++
 When you start GLHexen, there is information displayed in a console.
 If you play fullscreen or with a 3Dfx, you may miss this console. You can
 redirect it to a log file by using: GLHexen ..your command line switches here.. > log.log
 If you want to send me any problem, please attach this log.log file to your e-mail.
Screenshots:
++++++++++++
  You can make screenshots: use -ravpic & F1 key like the classic Hexen.
  A RAW file (GLshot.raw, flipped 640x480 RGB format) is generated.
  If you have a problem and want to send me a screenshot, please convert it to JPG (with PaintShopPro for example).
