  frustum culling
A standard visibility-culling technique is view-frustum culling, which eliminates objects outside of the current view frustum.
      
A disadvantage of the SPT algorithm is that within an SPT, no view-frustum culling can be applied.
      
Also view-frustum culling is not possible when there is no supporting data structure.
      
During the actual visibility culling, the OpenGL selection buffer is used to implement a view-frustum culling of the nodes of our subdivision tree.
      
Especially on these consoles view frustum culling and back-face culling are the most widely used methods.

This paper mainly introduces an object-oriented dynamic octrees that is suitable for roaming interactively in complex 3D scene in real time. According to space position relation of objects, the algorithm combines octrees, AABBs with the object-oriented concept to form a object-oriented dynamic octrees which can quickly update to refit the dynamic scene, its leaves include not only triangles of whole scene, but objects with AABBs. And then carries on frustum culling and collision detection and response based...

This paper mainly introduces an object-oriented dynamic octrees that is suitable for roaming interactively in complex 3D scene in real time. According to space position relation of objects, the algorithm combines octrees, AABBs with the object-oriented concept to form a object-oriented dynamic octrees which can quickly update to refit the dynamic scene, its leaves include not only triangles of whole scene, but objects with AABBs. And then carries on frustum culling and collision detection and response based on it. It is proved by practical running that this method overcomes the limitation that traditional octrees can not keep object's geometric and physical attributes, at the same time, gives full play to advantage of its space subdivision. It can quickly determine current interacting objects, reach the aim of accelerating rendering of scene and reduce the times of overlapping detection between objects.

利用对象间的空间位置关系,通过将八叉树、AABB树与面向对象概念相结合,构成一种能根据动态场景快速更新的面向对象的动态八叉树,其叶节点中包含的不是三角面,而是带有AABB层次树的物体对象.在此基础上进行摄影机裁剪和物体的碰撞检测及响应.实际应用表明,在克服传统八叉树算法不能保留对象几何信息、物理属性的局限性同时,又充分发挥其空间剖分的优点,使之快速准确地确定交互对象,达到加快场景渲染速度,减小物体间两两求交检测的次数的目的.
