By analyzing the disadvantage of the parallel rendering load balancing methods based on geometry data analysis , a load balancing method based on time - space conversion is presented which uses time value as the measure of a rendering node ' s work load and uses space value to control the distribution of work load . a reasonable algorithm is used to convert time value to space value 在分析已有的基于幾何數據分析的并行繪制負載平衡算法的基礎上,提出了浙江大學博士學位論文基于時空轉換的負載平衡算法:以時間值直接作為繪制節(jié)點負載的度量,以空間值控制負載的分配,通過適當方法完成時間值到空間值的轉換。
