| Abstract | Living Color Frame System (LCFS) is a personal computer software tool for generating real-time graphics applications. It is highly applicable for a wide range of data visualization in virtual environment applications. Engineers often use computer graphics to enhance the interpretation of data under observation. These graphics become more complicated when "run time" animations are required, such as found in many typical modem artificial intelligence and expert systems. Living Color Frame System solves many of these real-time graphics problems. INTRODUCIION Lewis Research Center is NASA's lead center in space power technology. Our technologies include the use of artifiaal intelligence (AI) for power management and distribution. Specific projects in AI are power scheduling, fault detection and isolation using expert systems [1,2], neural networks, and fuzzy logic. Power AI projects typically require real-time computer graphics that involve graphics image animation, such as alternating video colors and intensities and moving objects during run time. In some of our applications these images display the system hardware diagram and its real-time status (Fig. 1). The system process control variables must be displayed along with these graphical "frames." It is also desirable to be able to zoom in and out at any level of detail of these object images (hardware components) and to have the personal computer (PC) buzzer sound when operator response is urgently requested. Because considerable effort has been required to generate these real-time graphics applications, the need for an easy graphics generation and management tool became apparent. Although there are many sophisticated commercial graphics tools, such as Freelance (trademark of Lotus Development Corp.) and Quattro Pro (trademark of Borland International Inc.), none support or provide adequate, run-time software for graphics manipulation and/or disclose their graphics file formats for user implementation of real-time applications. Because such a tool was not available for PC use, we designed a new tool to eliminate custom grapliics programming and to simplify the development of our application software. It is called the Living Color Frame System (LCFS). This paper introduces the LCFS and presents an example of real-time graphics applications in the area of monitoring and diagnostics for an electromechanical actuator system (Fig. 1). |
