Aim: To study a method of accelerating 3D graphic scene rendering. Methods: By applying O-O (object-oriented) method to manage hierarchical 3D graphic scene data, the whole scene was divided into some scene areas basing on its complexity and these scene areas were divided againg into smaller ones by their visibility and so on, so 3D graphic scene was organized to be a tree and was accelerated to render. Results: A O-O method was presented to accelerate 3D graphic scene and has applied to a tank firing simulator for rendering the simulator's visual image more quickly. Conclusion: Rendering of graphic scene is the bottleneck in VR systems and modern simulators, this software is a part of immersion VR system and can serve the base of future development.
