Cyberware Color 3D Digitizer Demonstration Software for the Silicon Graphics 4D Series Workstations 3 May 1991 This tape contains an assortment of programs and images which you can use to evaluate the Cyberware Color 3D Digitizer. 1. Load the tape. If you have a cartridge tape drive on the local system: tar xvo A directory named 'cyberware_demo' will be created. About 10 Megabytes will be required to load the entire tape. If the cartridge tape drive is on another Iris try the following command or contact your system manager. Replace the word 'host' with the hostname of the workstation that has a drive. tar xvof host:/dev/tape 2. The simplest demo is performed as follows: cd cyberware_demo/easy (or as required) demo The windows may be individually terminated with the menu obtained when the right mouse button is depressed while in the window. 3. Other images are in the directory cyberware_demo/images. They may be viewed with the 'ipaste' command available on most SGI systems. cd cyberware_demo/images (or as required) ipaste steve_closeup ipaste heidi (et cetra) 4. The most powerful demo is accomplished with the program 'cyberware' and the digitizer image files in the directory 'data'. Your workstation must have RGB Bit-planes and Z-buffer for proper operation of this demo. More than the standard 8 Megabytes of memory will greatly speed the demo. cd cyberware_demo (or as required) cyberware Cyberware Color 3d Digitizer - Demonstration Software Cyberware> _ Various commands may be typed at the prompt. The command 'help' will display a list of the available commands. The commands fetch, display and exit are the most used. Read in an image file with the fetch command. For example: Cyberware> fetch heidi Where 'heide' could be the name of any file in the data directory. The file will be read for the image header information and surface data. The 'display' command will display the image. Cyberware> display The 'Help' window will be displayed. The program then computes the surface normals for the lighting computations. A 4D with less than 12 megabytes of RAM may require more than 1 minute for this computation. Cyberware then displays the data in both wireframe and smooth shaded form. Both the 'Wireframe' and 'Render' windows have pop-up menus. The menu is displayed with the RIGHT MOUSE BUTTON. A selection is made when the button is released. We use 'walking menus'. When a menu item has an arrow, push the mouse to the item and then right. A second menu will appear. Select from this menu by the same method. If the image has color information (some do and some do not), the natural surface will initially be displayed; otherwise, a lighting model will be used. In either case, you can use the "Surface Material" and "Texture Map Functions" menus in a variety of combinations to change the lighting and color representation of the image. TRANSFORMATIONS: The transformation selections operate by selecting them from the menu and then moving the mouse about. The LEFT MOUSE BUTTON will terminate the particular transformation and allow another selection to be made. It is quickest to do your transforms in the wireframe window, then redraw the shaded view. HELP: Watch the 'Help' window for clues as to what the program is expecting from you at any particular time. The standard GT 4Sight technique of holding the CTRL or ALT key during mouse movements will lend some sanity to mouse movements that cause the cursor to leave the window. Experimentation is best. We could explain it all here with several thousand words, but you might as well go ahead and experiment until we write them... Complete documentation is online. At the Cyberware> prompt type 'man man' or 'man display'. The command 'help' will display a list of all commands available in this version. The documentation covers all versions, and will search for keywords (e.g. try 'man mill'). Actually the documentation isn't 100% complete. STEREO DISPLAY: If you have the stereo option StereoView or CrystalEyes you can put this demo in stereo mode. At the Cyberware> prompt type: Cyberware> stereo This sets some parameters in the software by reading the file source/stereo. When you then use the display option the monitor will switch to stereo mode. Only one window will be displayed at any one time. To switch between the wireframe and render windows use the menu selections provided. The Meter feature does not work properly in stereo mode. The Perspective control works, but not is properly designed for stereo. There is no way to return the demo to non-stereo mode except to exit the demo and restart it. You may want to put the Render Window into Doublebuffer mode. The Oscillate selection on the Render Window Transform menu is interesting on the faster workstations (GT...VGX). 5. The directory 'convert' contains some conversion utilities which will convert the cyberware range maps into other industry-popular formats. See the README file in that directory for further information. 6. If we have sent you special data it will be in a directory named 'custom', 'siggraph' or another name specific to your tape. Use the Unix command 'file' to determine what type of file has been provided. The response of 'file *' will indicate: data A Cyberware file, use the program 'cyberware'. SGI... A SGI imagelib image, use 'ipaste'. ascii text Probably a Cyberware file converted to some other format. directory Another directory level, use 'cd' and 'file' again. Color Cyberware images will have two files. One contains the geometry and the other contains the color or texture map. This file will have the extension .color. The color files are in standard Silicon Graphics RGB format. Try the command 'ipaste heidi.color' for an example. Support for this format is found on most workstations in the directory named /usr/people/4Dgifts/iristools/imgtools.
