The National Aerospace Laboratory (NAL) has a flight simulator for research and development of aircraft. The flight simulator is composed of a cockpit system, a visual system, a motion system and a computer system for real-time calculation. A visual system is indipensable for piloted aircraft simulation. In 1966, NAL installed a visual system with a miniature model board. It generated imagery by using a servo-driven TV method. However, several years later it was requested to improve the movement speed and the range. In 1983, NAL upgraded the visual system to a CGI (Computer Generated Imagery) type system for the research and development of a new STOL (Short Take-Off and Landing) research aircraft. A CGI type visual system needs a large visual digital data base for a wide range scene. NAL developed the Interactive Model Assembly Program (IMAP). It is easy to make a visual data base with this program. The Characteristics of the IMAP are as follows. (1)Interactive generation of visual data base (2)Ease of editing a visual data base (3)Fast searching of visual data base (4)Real-time display of visual data base (5)Line drawing of a visual scene by using a graphic display Up to the present the IMAP has been used for various simulation tests, such as the NAL STOL aircraft simulation, spececraft rendez-vous simulation, and re-entry simulation of a space plane. It has been proven that the program contributes to decreasing the time needed to make visual data. In this report we will describe the IMAP functions and its hardware configuration in use. Lastly we will show comparison results between the IMAP and the BMAP (Batch-type Model Assembly Program).
