A Method of Quickly Constructing and Rendering 3D Graphic Scene

Aim To study a method of constructing and rendering 3D graphic scene quickly. Methods Through analysing 3D scene data and applying O O(object oriented) technique, the hierarchical data structure of 3D graphic scene was built and a method of consturcting and rendering 3D graphic scene quickly was realized. Results This method has the qualities of extensibility and reusability by means of O O method and the variable resolution technique and instance technique can also be used for accelerating graphic rendering, so 3D graphic scene can be constructed and rendered quickly. Conclusion By applying O O method to manage hierarchical scene data, both constructing and rendering 3D graphic scene are accelerated.
