The application of temporal - spatial coherence in multi - object collision detection 時空相關性在多物體碰撞檢測中的應用
Spatial coherence function 空間相干函數
Temporal and spatial coherence , two - beam and multiple - beam interference , interferometers 4 4時間與空間同調,二至多道光干涉,干涉儀。
Unlike ray casting , where each image pixel is built up ray by ray , this approach takes advantage of spatial coherence 但與光線投射算法不同的是,此算法利用空間信息對穿過同一切片的所有光線同時處理。
The dimension of the very large floating structures ( vlfs ) is usually more than 1km . the design of such giant structures must consider the spatial coherence of waves . crest length is one of the main parameters in wave coherence 超大型海上浮體結構( vlfs )的尺寸通常以千米計,對于如此尺度的結構,作為主要環境因素的海浪必須考慮其在空間上的不均勻性。
In this dissertation , the progress in the researches of spatial coherence of random waves is reviewed . based on this , studies have been carried out for the statistical characteristics of crest lengths and their influence on vlfs 本文回顧總結了近年來國內外有關海浪空間特征量統計研究的進展,并在此基礎上,開展了隨機海浪波峰長度統計特征及其對海上結構物影響的研究。
From the geometric limit of light source , the paper discusses the arrangement for geometric size of non - coherent light source which affects the visibility of coherent pattern and gives the essential of the spatial coherence 摘要從普通光源線度的幾何約束出發,較詳細地討論了非相干光源線度及其干涉裝置參數的設定對其干涉效果(視見度)的影響,進一步論述了空間相干性的物理本質。
Recently , litovitz et al raised the spatial coherence theory of electromagnetic field ( emf ) . the theory thinks that regular mf is spatial coherence field and noise mf is spatial incoherence field , the noise mf could inhibit the biological effects induced by mf 近年來, litovitz等提出了電磁場的時空相干理論:認為規則電磁場是相干場,可誘導生物體產生效應,而噪聲磁場為非相干場,可以干預前者的生物效應。
This paper analysis three kinds of deformations and propose resolving method respectively . a bottom - up updating method is propose especially which can compute the bounding volume of parent node through bounding volumes of the two children by k comparison . furthermore , a traverse tracing strategy that can speed up collision detection is proposed in this paper based on developing and utilizing temporal - spatial coherence in virtual environment 本文在對幾種變形情況進行分析的基礎上,分別提出了相應的解決方法,并著重提出了一種自底向上的包圍盒樹快速更新算法,通過k次比較運算由子結點的包圍盒得到父結點的包圍盒,以解決拉壓變形和拓撲變化后包圍盒樹的更新問題。
