Study on Scene Graph and its Application in Product Design

摘要

Based on the study of the characteristics of scene graph and OSG, osgART and its application in product design was deeply analyzed. Organizational characteristics of scene graph, node traversal, interaction and update callback method in osgART were studied, and relevant codes were given. By adopting OSG scene graph to organize and manage scene information, the developments of AR applications with osgART can simply programming and increase application running speed. The real-time interactive capabilities of virtual objects with real environment can be enhanced, which meet the requirements of rapidly developing AR application with rich features. At the end of this article, a design review system with above approaches for product design was introduced.
