The algorithm first divides the scene into certain layers that do not intersect each other by light's frustums in light space, and generates one shadow map for each layer to ensure that any shadow map does not have the same sample points. Then a faster synthesizing scene shadow method, which avoids operations of pixel layer determination, is given to improve GPU's efficiency.

在光源空間中天天色天天日天天干，利用光源視錐體將場景劃分為不相交的多層區(qū)域人人弄人人玩人人搡，利用GPU為各層生成陰影圖，以確保場景采樣點不在多層陰影圖中重復(fù)出現(xiàn)国内外免费激情在线视频；同時給出了一種快速綜合場景陰影效果的繪制方法亚洲哟哟精品网站，通過避免判斷像素層次的操作提高了GPU的利用率。

By analyzing the forging process of double frustums sucker rod and using rigid visco-plastic material model and 3-D coupled FE simulation, the whole forging procedure are analyzed and simulated with finite element analysis software DEFORM. The results indicate the inner stress field, strain field, metal flowing law and forging travel-load curve during the forming procedure. The forming statuses, causation of defect of workpiece are predicted and so on.
