The randomized z - buffer algorithm : interactive rendering of highly complex scenes
這是為了由近及遠地處理點數據。 -
Another 20 kinds of non - designed contact points are given for the first time. contact determining algorithm of all the above contact types is given using z - buffer algorithm for 3 - d observation, and simulation results show high accordance with results of vector - associated method. simulation for non - designed contact mode with random initial conditions has been done too, and statistics from the simulation indicates that it is important to predict non - designed contact points in practical rvd efforts
全文的工作包括以下幾個方面的內容: 1 .建立了周邊式對接機構的復雜幾何外形的數學描述，描述了對接初始條件范圍內，兩對接機構相互接近、捕獲過程中可能出現的20種設計接觸模式，並針對初始接觸點首次提出20種非設計接觸模式;利用計算機圖形學中可見面判別的z -緩沖演算法原理，給出了所有接觸模式的檢測演算法，該演算法的模擬結果與輔助向量法高度一致，驗證了演算法的有效性;進行了300組確定首次接觸點的隨機模擬，統計結果表明，在飛船上實時進行非設計接觸模式的預測是非常重要的。 -
We combine the algorithm of ray casting and z - buffer to rebuild 3d data, and use marching cubes to create iso - surfaces in 3d regular data sets. several common spatial interpolation are discussed in this thesis, and the famous kriging algorithm in the geological statistics is the emphasis. - four interpolations are used in the case of study, and the results are compared in this thesis
在系統實現中，針對兩類演算法的不同特點，在不同的模塊中選用了兩類演算法中的經典演算法：提出將光線投射法與z - buffer演算法結合實現三維體數據重建；使用移動立方體法實現三維數據場的等值面繪制。
