WELCOME TO VERISCOPE

The software that brings reality to your 3-D CAD work!  Move 
through model space in real time and see things as they are 
meant to be seen.  Fast shading and quick production of fully 
shaded animation sequences together with interactive stereo 
viewing make VERISCOPE the best tool for presenting your 
ideas.  

This section of the VERISCOPE Demonstration Guide tells you 
about the hardware you will need to run VERISCOPE, and takes 
you through your first session with one of the sample models.


WHAT YOU NEED TO RUN VERISCOPE Demonstration

*  386 (or better) IBM Compatible PC with Math Co-processor
*  DOS 3.0
*  VGA Video Card with colour monitor
*  Mouse with Microsoft Compatible Driver
*  Hard Disk with 2 megabytes free disk space.
*  640 KBytes RAM Memory

The Extended memory is best used for disk-caching software 
such as Microsoft's Smartdrive.  You can also use a RAM 
Disk.  If you do, set the environment variable TMP to the RAM 
disk.

EXAMPLE  >SET TMP=E:\


GETTING STARTED:  INSTALLING THE PROGRAM

Insert the disk labelled VERISCOPE Demonstration DISK in the 
drive you want to use for installation and close the drive door.  
In this example we assume the installation drive is drive A:

*	Type  A:INSTALL and press ENTER.
*	Follow the instructions in the install program
VeriScope uses files in the MOD format.  These files contain 3-
D information in a compact and easily manipulated form.  
VeriScope can convert 3-D elements from a DXF file into the 
MOD format. This function is NOT disabled on the demonstration 
program. The VeriScope demo disk contains a number of 
sample MOD files for you to use. You have now completed the 
installation procedure.

SUPER VGA

We recommend that you load a VESA compatible BIOS for your 
SuperVGA card if necessary. 

MOUSE

Veriscope Requires a  Microsoft Mouse compatible pointing 
device.
You may need to load a driver to make your pointing device 
appear as a Microsoft Mouse to the program.


SAMPLE EXERCISE

We will now start this sample exercise using the sample file 
ROOM.MOD.

*	Type VDEMO ROOM and press ENTER.

At this point you should see the VeriScope License Screen.  If 
you do not see this screen please refer to the next section 
entitled "VSCOPE Will Not Run".

VeriScope is now checking your video and mouse set-up.  
First, it verifies that there is a colour VGA connected.  Then it 
checks for a Microsoft compatible mouse driver and that a 
mouse or other pointing device is connected.  If these 
conditions are satisfied, it then checks for a VESA compatible 
SuperVGA.  If not found, it then goes on to check if it 
recognises the SuperVGA set-up.  The higher resolution modes 
are enabled automatically.  Some information about the Video 
Setup is displayed. 

*	At the License screen press ENTER.

You should see the ROOM displayed and across the top is a 
menu bar.  Move the cursor to the VIEW heading and press the 
left mouse button.  Drag the cursor down the box to the 
DYNOVIEW option.  Release the mouse button.  Draw the 
mouse towards you.  You see the room rotating as you move 
the mouse.   
Press the space bar to go back to the menu.  Go back to the 
VIEW menu and click on the 3D-WALK option.  Put on the 
coloured glasses.  Hold both mouse buttons down and push 
the mouse away from you.  Hold the right button down and 
move the mouse from side to side.  Press the space bar to go 
back to the menu.  Take off the coloured glasses.

For more information on the 3D WALK and DYNOVIEW, see 
chapter 3 'Using VeriScope'.

Pull down the Main Menu and click on the Shade option.


 

VSCOPE WILL NOT RUN

If VeriScope will not run there will be a message above the 
DOS Prompt.  

Message:	"Bad command or file not found" 
Make sure that the current directory contains the file 
VDEMO.EXE.  You should by now already be in the VSCOPE 
directory, i.e. in the directory containing DEMO.EXE.  If you are 
not: Type CD VSCOPE and press ENTER.  Then try again by 
typing VDEMO ROOM, and press ENTER. 

If the same message persists, try to install the program again.

Message :	"Unable to Load VDEMO.EXE" or 
		"Insufficient Memory" 
These messages indicate that you do not have sufficient free 
DOS Memory to run DEMO.  VeriScope requires 467,000 Bytes 
of memory.  Run the DOS program MEM.COM to see how much 
free memory you have.  You may need to remove some TSR 
programs or device drivers.

Message:	"Co-processor not installed" or equivalent
This means that you do not have a math-co-processor installed 
on your system.  In this case, you must use a different version 
of VeriScope. The demonstration disk does not contain the non-
coprocessor version of VeriScope.


A QUICK REVIEW OF THE COMMANDS

MAIN
SHADE 	Shades the current picture.
REDRAW	Draws the current picture
CLEAR	Clears the screen
RESET	Full plan view of the drawing
PART SHADE	Shades a user defined area
DRAW MODE	Sets the line drawing video mode
SHADEMODE	Sets the shading video mode

VIEW
DYNOVIEW	Displays the entire drawing resets the focal 
distance and allows interactive rotation about 
a central point.
WALKTHRU	Allows user interactive viewing and 
movement through the model space
3-D WALK	Same as WALKTHRU but stereoscopic 
viewing for use with the coloured glasses.

ZOOM
ALL	Displays the full last view 
PAN	Pans across the view
WINDOW	Zooms a user defined box to screen size
AUTO	Zooms the image to full size 
DYNAMIC	Interactive positioning of the view
4-VIEW 	Divides the screen into 4 parts and shows the 
three principal views with light position and 
viewing fulcrum. Also shows a small shading 
of the current view.
