Abstract
Scene space organizational structure and visibility culling plays a crucial role in the quality and efficiency of subsequent rendering. To improve the real-time rendering of indoor and outdoor objects and enhance the organization efficiency of scenes, we propose an optimized scene management structure for fast visibility culling. We organize the scene into an adaptive binary tree (ABT) structure to make full use of the characteristics of high accuracy of ABT space subdivision and strong adaptability of scene graph. Based on its structure and the basic principle of view frustum culling (VFC) algorithm, a double-layer visibility culling algorithm is proposed to further improve performance and to compensate for the existing low VFC efficiency. The results of experiments prove its high efficiency for handling complex scenes with large amount of triangles in high depth, accelerating real-time rendering speed of complex scene.
