But for dense data sets,currentm ethods of view frustum culling and crack elim inating often lead to decline in performance.
大规模地形的实时漫游算法一般采用视见体裁剪和与视点相关的连续细节层次等技术来减少实际绘制的地形数据量 。
In addition,dynamical management of terrain dataset in view field was implemented effectively by visible detection based on the simplified view frustum and terrain data prediction strategy.
此外,简化视见体的可见性判断和数据预取策略,实现可见数据的动态管理。
