Digital mock-up database simplification with the help of view and application dependent criteria for industrial virtual reality application

摘要: Aircraft cockpits are advanced interfaces dedicated to the interaction and exchange of observations commands between pilot flying system. The design process is benefiting from use Virtual Reality technologies: early ergonomics layout analysis through exploration numerous alternatives, availability all along cockpit life cycle a virtual product ready for experimentation, reduced usage costly physical mock-ups. Nevertheless, construction with adequate performances very complex. Due fact that CAD based digital mock-up used setting up large, one challenge achieve interactivity while maintaining quality rendering. reduction information contained in database shall sufficient frame rate without degradation geometrical visual which would alleviate relevance studies. This paper proposes control simplification by using objective criteria on considerations about application human beings. First, it presents results studies characteristics Human Visual System linked reality visualization applications. Illustrated first results, establishes how simplifications rational automatic way.
