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 backgrounds SHADESTYLE Set the shading algorithm. INFO Displays information about the current drawing RENORMAL Recalculates the surface normals based on new adjacent surface normal constraints. SET COLOUR Select new 16 colour palette WALK MODE Toggles between two methods of piloting in model space. The zoom mode uses the S and F keys for forward back motion PROJECTIONS Toggles between two methods of presenting the 4-View.(second or third angle) HOT BUTTS Coded system control. Also displays the 256 colour palette in 256 colour modes DRAW FACES Draws each face instead of just the lines. TEST Recognises faces and lines for testing continuity between faces. LENS MM Sets the lens size. FILES GET MOD Reads in a MOD File. NOTE: VeriScope requires a default MOD file to run properly GET DXF Reads in a DXF file, converting it to MOD format and generating a MOD file of the same name. GET PCX Displays a PCX file. GET MOVIE Plays a movie file. EXIT Exits VeriScope. DIR Lists all files, switches directories, allows direct viewing of a file in ASCII format. CAPTURE Records the current screen to a PCX file. MOVIES MOVIE Movie generation. PREVIEW Preview line drawn frames of a movie before actually generating the movie. KEY FRAMES Resets the Key Frame count to zero. BACKGROUND Specify background PCX file for movies. X->Y->Z Change Vertical Axis.
