The Research And Implementation Of Dissassembly/Assembly Technique Based On Virtual Reality

There are some special requirements in training-oriented system for assemblage and principle demonstration. System based on playback of prerecorded video lacks interactivity; System based on multimedia making system cannot present uses'particular intent because of its limited function and running path. Therefore a new way of thinking that training-oriented system based on virtual reality is approached. This paper carries out extensive and thorough studies on it. The technique of virtual modeling technology, the constraint relations between parts/components, the technique of scene simulation and collision interference detection technique on virtual scenes are discussed in this thesis.The geometry construction in the method and MultiGen Creator that tools of 3D construction for real time is mainly discussed. Some key technologies about a visual system constructed are studied. The paper introduces how to solve the key technologies in visual simulation based on visual management software—OpenGVS, for example, optimizing the three-dimensional objects and the technology of Screen Pickup, showing Chinese characters to screen and Collision Detection.Collisions detection technology, the key technologies based on virtual equipment disassembly/assembly, is explored. This paper put forward a new collision detection algorithm that is a virtual assembly-oriented relative position collision detection algorithm, which can detect collision more effectively. It meets the real-time nature of the request and reduces complexity of collision detection.Based on the research of the above problematic situation, disassembly/assembly system has been developed using OpenGVS. Some critical disassembly/assembly techniques based on virtual reality have been implemented.
