VREAM Installation Procedure
============================

Overview
--------

The VREAM Virtual Reality Development System is contained in a compressed 
format on four 3.5" 1.44 MB high density diskettes. The VREAM System must be 
installed on a hard disk drive in order to be executed. In order to install 
the VREAM System, about 11MB of space is required on the target hard drive.

The VREAM Virtual Reality Development System includes an installation 
program, which will install the VREAM System onto your computer. The 
installation program will ask you a series of questions in order to determine 
the appropriate hard disk drive and subdirectory to use for the installation. 
The installation program will then prompt you to insert each of the disks 
into the floppy disk drive so that the files on the disk may be decompressed 
and installed onto the hard drive. Step by step instructions are provided 
below.

Installing the VREAM System
---------------------------

To start the VREAM installation program, insert VREAM Disk #1 into a 3.5" 
diskette drive. The following commands will assume that your 3.5" disk 
drive is designated as Drive B on your computer. If your 3.5" disk drive has 
a designation other than B (such as A), then substitute that letter for B 
in the following commands.

With VREAM Disk #1 inserted into the 3.5" disk drive (Drive B), execute the 
following command to change the active disk to drive B:

B: (enter)

This will display the standard DOS prompt as shown below. Remember, if 
your 3.5" disk has a designation other than B, then use that letter in place 
of B.

B:\>

To invoke the installation program, at the DOS prompt type:

B:\>INSTALL (enter)

When the installation program begins, it will display an introductory screen. 
This screen contains a general description of the installation process. It 
also contains a reminder that the VREAM System requires about 11 MB of 
space 
on the hard drive. The installation program will automatically verify that 
enough space is available on your hard drive before beginning the 
installation procedure.

As the VREAM installation program continues, you will be asked a series of 
questions. The installation program will provide you with default answers to 
the questions. If a default answer is correct, press the Enter key in 
response to the question. Otherwise, type the desired answer and then press 
the Enter key. 

At this point, if you wish to cancel the installation procedure, you may 
press the [Esc] key. If you wish to continue, press any other key.

The second screen of the installation program allows you to choose the hard 
drive onto which you would like to install the VREAM Virtual Reality 
Development System. If the default drive (the flashing one) is correct, 
simply press the Enter key. If you wish to choose another drive, use the up 
and down arrow keys to move the flashing bar to another option, and then 
press the Enter key.

The third screen allows you to choose the directory into which you would 
like to install the VREAM System. If you would like to use the default 
directory, simply press the Enter key. If you would like to use a different 
directory, backspace over the default directory name, enter the name of the 
desired directory, and press the Enter key. 

If the entered directory does not already exist, then it will be created. If 
you are installing the VREAM System into a directory which does already exist 
then any files which contain the same names as the files being installed will 
be overwritten.

The fourth screen allows you to verify that the previously entered hard disk 
drive and directory name are correct, and to confirm whether to proceed with 
the VREAM installation. The default flashing option within the window will 
allow the VREAM installation to proceed. If you would like to select the 
default option, simply press the Enter key. If you would like to cancel the 
installation procedure, press the down arrow to move the flashing bar to the 
Cancel VREAM Installation option, and then press the Enter key.

The fifth screen explains how the installation process works, and begins that 
process. During the installation process, you will be prompted to put each of 
the VREAM diskettes into the floppy disk drive. Each VREAM floppy disk 
contains a series of compressed files which will be decompressed and 
installed onto the hard drive. This process will take a few minutes for each 
disk.

As the installation program works, it will display the name of each VREAM 
System file as it is decompressed, installed in the target directory, and 
verified.

When the files on the first disk are completely installed, the installation 
program will prompt you to insert Disk #2 into the floppy disk drive. At 
this point, you may remove Disk #1 from the disk drive and replace it with 
Disk #2. 

When prompted to do so, repeat the process with Disk #3 and Disk #4.

When the installation process is completed, the program will prompt you to 
re-insert Disk #1. This will finalize the installation procedure.

The installation program will then prompt you to hit any key to return to 
DOS. Upon returning to DOS, you will be located in the directory containing 
the newly installed VREAM Virtual Reality Development System.

Currently, in order to execute the VREAM System, all of the VREAM System 
files, VREAMScript files, and supplemental files must be contained in the 
main VREAM directory.

VREAM System Updates
====================

This section contains a list of updates made to the VREAM Virtual Reality 
Development System. The updates are listed under the Version number in 
which they were implemented.


Version 1.0001
--------------

Extrusion Object Primitives are handled properly within Group Objects.

DXF Files that do not contain Table and Block data may be imported without 
generating a DXF file read error. 

The VRMCFIG.SYS file contains the proper PGLOVE_ VREAMScript 
Interface Device commands.

The sample world CRYSEYES.VST now uses the runtime graphics mode 
number 100 instead of mode number 19.

The size of the PCX texture file pine1.pcx was reduced so that it contains 
less than 65535 total pixels.


Version 1.0002
--------------

The WORLD_TO_VIEW_COORDINATES and 
VIEW_TO_WORLD_COORDINATES link response commands were updated 
so that they now work properly.

The DXF Import facility now supports Polyface Mesh Entities.

The DXF Import facility now supports Blocks containing other Inserted 
Blocks.

The DXF Import facility now performs memory checks to make sure that 
enough memory exists to load the DXF file.

When a DXF file is imported into the 3D World Editor, the environment 
Wireframe attribute is automatically set On, and the environment Solid 
attribute is automatically set Off. This improves the speed at which the 
imported DXF object will be initially drawn, and allows for easy 
visualization of all of the imported DXF entities.

The SCRIPT_CALL link response command now allows a new world to be 
properly loaded with object elimination on, and the hand displayed.

In the VRMCFIG.SYS file, the default value of the 
JOYSTICK_CONFIGURATION Interface Device command was changed 
from 2 to 1.

The sample world JUKEBOX1.VST now has the SOUND world attribute set 
On.

The sample world JUKEBOX2.VST now contains a link that will play a sound 
when the juke box is pushed.

Object Elimination has been set off for the sample worlds SCRPTCL1.VST 
and SCRPTCL2.VST.

The README.TXT file is included on Disk #1.


Version 1.0002b
---------------

The Install program was added.


Version 1.0003
---------------

Object variables may attempt to access objects that are not yet created, 
without causing the system to crash.

Objects will properly respond to multiple gravity surfaces within an 
environment.

A Throw link response may be activated in response to the Initialize link 
condition.

Variable names greater than 12 characters long are properly handled.

Character literals used within a Variable link condition or link response 
command, will be surrounded by double quotes when saved from within the 
3D World Editor, or by the SCRIPT_SAVE link response command within the 
Runtime System.

Group objects consisting of only one object, may be created dynamically 
within the Runtime System, without causing the system to crash.

Links within an environment other than environment #0, may be edited within 
the 3D World Editor, and successfully saved within their proper environment.


Version 1.0004
---------------

Internal memory allocations within the parser have been updated.

The System variables SI_YEAR, SI_MONTH, and SI_DAY have been 
enabled.

The 3D World Editor will properly save System variable names which are used 
within the Text parameter of an INFO_TEXT command.

The World | Set Colors | Assign Shades menu option within the 3D World 
Editor will display an information window that says "This Option Is Not 
Enabled".
