In this method the relationships between visual point and scene space are analyzed for pixel space identification to avoid the blindness of task partitioning, the load balance is guaranteed by using nsota approximate algorithm 該方法通過分析視點與場景空間的關(guān)系,進行像素空間的劃分,避免并行處理任務(wù)分配的盲目性;采用近似的nsota算法保證了任務(wù)分配的均衡性。
