1.1 Installation instructions
---------------------------------
Please read the install.txt file for instructions.  This is essential
if you want to compile the programs with few problems.


2.1 Using the Utilities
-----------------------
The utilities are designed to be run from a directory other than where
the executable exists.  You MUST add either \pr\bin or \pr\winbin to your
path statement in your autoexec.bat file, depending on if you are using
the DOS or Windows version.  You must reboot for this change to take
effect.  After doing this, you can run any of the utilities from any
directory on your system.  This means you can make a directory, put all
your objects and textures in it, and work on them without worrying about
where the utilities are located.  You MUST NOT type any directory before
the utility name when you run it.
ie do not type "c:\pr\bin\texskin duck.pro"
Some of the utilities need data files that exist in the current directory
and they will not be found if you do this.


You must have the guidata.prl file in the same directory as your program,
if you are using the graphical user interface functions such as mouse
routines.  This file contains the graphical data needed for the GUI
library and startup screen.


3.1 Documentation
-----------------
Our documentation is in the Microsoft Word 97 format.  If you do not have
Microsoft Word, you can download a separate Word Viewer application.
See http://www.microsoft.com/word/Internet/Viewer/default.htm
for more information.

This release is integrated with WGT 5.1 and WGT95.  You do not need these
libraries to link a Power Render application, however the full WGT 5.1 and
WGT95 products contain more libraries and content than Power Render alone.
The Power Render libraries include the main WGT library and the scrolling
library (which is used by the terrain demo to load tiled maps).  The
rest of the libraries are included when you buy Power Render.


4.1 Release Notes
-----------------
This is a final version.  There are still some bugs left and I will release
some maintenance patches later.  However this will probably be the last
major version of Power Render.

- Known bugs:
- For some reason the WinGlide versions of the PHONG utility crash.  You
should use the dos version if you need this utility, or figure out what
I did wrong :)

- I also noticed a bug in the DirectDraw/D3D versions of the terrain library.
The terrain bitmaps seem to use the wrong pitch with bitmaps that are not
a multiples of 8.

- I am using an AT3D Voodoo Rush development board and it seems to have
trouble switching resolutions.  It will lock up after running a 640x480x16
application with a Win95 desktop running in 800x600x16.  If you keep your
desktop in 640x480x16 it seems to work fine.  Also, if you run the DirectDraw
versions of the utilities the mouse cursor smears the background.  There
is a bug in their DirectDraw drivers because it works fine on a
Matrox Mystique.

- Holes in terrain rendering when using software rendering.  Note that you
  can hide this if the sky color is black.
