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.
LIGHTS
LIGHTING Set light positions. Attach lights to camera
LAYERS Set layer colours, surface reflectance and
shininess
REFLECT Displays a Phong shaded sphere as it would
appear at the view target with the attributes of
the zero layer. Used for testing Phong shading
parameters and light position.
NO CLEAR Turns the screen clear off until the next redraw
command. this is useful for shading over PCX
