三维游戏场景中动态物体的遮挡剔除算法

在游戏场景中使用遮挡剔除技术后会比不使用的场景提高30%到70%不等的FPS,所以应尽量将遮挡剔除技术加入到游戏引擎中,而且遮挡剔除技术并不是只能使用到portal引擎中,它可以被使用到任意技术构建的引擎中。而由于现存的遮挡剔除算法对动态物体达不到真正的剔除,本文提出了一种剔除场景中动态物体的算法——区间扫描线Z缓冲器算法,并阐述了该算法的基本原理及实现步骤。

An Occlusion Culling Algorithm for Moving Objects in 3D Game Scene

Uses after the occlusion culling in game scene which the technology can compare does not use enhances 30% to 70%FPS, therefore will be supposed as far as possible to the occlusion culling technology joins to the game engine in, moreover it canuse in the portal engine, even could use in the engine which the free technical construction will construct. But because extant occlu-sion culling algorithm does not reach true culling to the moving objects, this article proposed one kind culling in the scene the mov-ing objects algorithm- sector scan line Z buffer algorithm, and elaborated this algorithm basic principle and the realization step.
