1	Introduction

	This file explains how to install and uninstall the GLoria Heidi
	driver. After the installation process you find additional
	documentation in the help file.
	
1.1 	List of files

	After a successful installation you will find the following
	files in the destination directory:

	GLoria.HDI	Heidi driver for GLoria
	GLoriaEN.HLP	English help file
        GLoriaDE.HLP    German help file

	README.TXT	The file you are reading
	LIESMICH.TXT	German translation of README.TXT

1.2 	How to determine the driver's version number

	There are several ways to get the version number of this driver.

1.2.1 	Using the File Manager or Explorer

	Open the properties of the file GLoria.HDI with File Manager
	or Explorer to read the version string.

1.2.2   Using the file GLoria.INI

	Open the file GLoria.INI in the main directory of 3D Studio MAX.
	The line "GLoria_Driver=..." shows the exact version string.

	Note: This file does only exist if the driver has been used
	      at least once by 3DS MAX/VIZ!

1.2.3 	Using README.TXT

	At the top of this you should find a header indicating the
	version number. In rare cases this might be outdated, however.
	The first two methods are preferred.

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

2	Installation/Uninstallation

2.1     Prerequisites

	Please check the following list of requirements to allow
	sucessful installation and usage of this driver.

	- operating system Windows NT 3.51 or 4.0 (Intel)
	- ELSA Windows graphics driver v4.08 or later
	- 3D Studio MAX v1.0, v1.1, v1.2 or 3D Studio VIZ Pre-Release, 
          already installed
	- graphics controller GLoria-4, GLoria-8, GLoria-S, GLoria-M or 
          GLoria-L
	- graphics resolution, which allows for "Double Buffering"
	- color depth of 15bpp (32K colors) or 32bpp (Truecolor)
	- write access to 3D Studio MAX/VIZ' main directory and its
	  subdirectories

2.2 	Procedure of Installation

	Please make sure 3D Studio MAX/VIZ is _not_ running.

	Start SETUP.EXE from the same directory that contained this
	README.TXT file.

	The program will progress as follows:

	- Welcome message

	- Query for your 3D Studio MAX/VIZ main directory. The preset 
          path is the copy of 3DS MAX you installed most recently; in 
          case you have more than one installation on your system you 
          might have to adjust this. Use the "Browse" button to find 
	  the proper directory.

	- Query for the Program Group to hold the icons of the help 
          file and the uninstall program.

	- Copying of all files to the directory Drivers in the indicated
	  main directory and storing of uninstall information.

	- Adjustments in 3DSMAX.INI or 3DSVIZ.INI resp.; the former 
          contents of this file is copyied to the file 3DSMAX.INO or
          3DSVIZ.INO resp..

	- Creation of icons the indicated program group.

	- Success message


2.3 	Uninstallation

	The install program records uninstall information, either in the
	chosen program group or in 
        Start/Settings/Control Panel/Add-Remove Programs.

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

3	Differences of GLoria.HDI vs. WGLINT.HDI

	GLoria.HDI is developped on base of WGLINT.HDI, the Heidi driver
	of 3Dlabs for the GLiNT family of graphics chips.

	GLoria.HDI includes some bug fixes and improved performance, and
	should therefore used on ELSA GLoria instead.

	Texture interpolation in GLoria.HDI supports two modes: the
	default of nearest neighbor, and linear interpolation.

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

4       New Features with version 2.00.00

        - Support for GLoria-L/MX, GLoria-Synergy and GLoria-XL.

        - Page flip double buffering is supported. It is imperative that 
          the current display driver also supports page flipping. This 
          feature immensly improves the drivers performance, especially
          when animating complex scenes. The feature is implemented
          as a user option. It is on by default. Page flipping needs the 
          data to be consistent in the front and back buffer. Because 
          some applications are using a mix of 2D (GDI) and 3D (OpenGL) 
          commands within a 3D view, this consistency cannot be guaranteed. 
          The user then may activate the safe but slower buffer blit 
          method. To do so, activate the "Force Buffer Blit" option 
          within the GLoria Settings. 
        
        - The texure caching mechanism was improved.

        - Support for 3D Studio VIZ Pre-Release.    

4.1     Changes with version 2.00.01

        - A problem with true color textures on a GLoria-Synergy 
          has been fixed.

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

5       Known problems and restrictions 

        Colordepth and resolution
        -------------------------
  
        This driver is not supported in 8bit color mode.

        A resolution lower than 800x600 pixels is not supported.

        Multiscreen
        -----------
        In multi screen mode, 3D Studio MAX/VIZ should always be started 
        on the primary (boot) screen. Otherwise display errors may appear.

        Page Flipping 
        -------------
        If page flipping is enabled, the contents of viewports may become 
        corrupted. In particular, when using software cursors or if the 
        viewports are overlapped by other windows (e.g. Renderer), garbage 
        or other artifacts will be left on screen.  A redraw will clean up 
        the viewports immediately. The redraw must be done manually by the 
        user.        

        Distortion in perspective view 
        ------------------------------
        If two simple objects (e.g. boxes) intersect one another in a way 
        so they form a plane at one of their sides, rendering artifacts 
        may appear. This problem can be solved by increasing the segmentation 
        for those objects.     
        
        General
        -------
        If 3DS MAX/VIZ is dragged off screen and then dragged back to 
        screen, the contents of the windows may become corrupted and the 
        application will not refresh the display. This refresh must be 
        done manually by the user.
