【正文】 6 總結(jié) 被展示 出來 的虛擬模型 給我們 提供一 個(gè) 觀察捷克共和國(guó)空氣污染情況的可能。給節(jié)點(diǎn) 命名允許之后的 VRML節(jié)點(diǎn)參數(shù)的修正， Matlab 環(huán)境下 VRML程序節(jié)點(diǎn)參數(shù)必須在 .wrl文件中被定義。圖 1里 關(guān)于 Delaunay三角形方法被用在高階插值中（雙線性，立方 體，線條）。 這篇論文的目標(biāo)是使用 Matlab系統(tǒng)來 對(duì) 捷克共和國(guó)空氣污染等級(jí)的三維模型 進(jìn)行處理，并且使用虛擬現(xiàn)實(shí)建模語 言作為最終的表現(xiàn)形式 。 For noncalculator professional personnel to say, make use of OpenGL to write a plicated 3D application doubtless is a challenge. VRML language oneself writing is very easy, but this kind of language function be weaker, and it seems to be to lack the ability to do in the aspects of handle plicatedly progress, with other high classic language of the conjunction be also not enough convenience. Direct 3Ds are a 3D sketch plait distance API that the Microsoft panies release, it mainly applied at the plait distance of 3D game, needed to weave a distance a personnel to have higher ability of C++. High language of plait distance achievement bottom, as a result is also hard and universal. Therefore establish a virtual realistic scene to need to there is better plait distance through this kind of path ability, need to acquaint with a certain language in the meantime, suitable for professional development personnel。目前最常用的互聯(lián)網(wǎng)瀏覽器（微軟的 IE瀏覽器和網(wǎng)景的領(lǐng)航員瀏覽器）已經(jīng)內(nèi)置了瀏覽虛擬現(xiàn)實(shí)建模語言的插件。對(duì)這些問題的描述和對(duì)比已經(jīng)在圖 [4]中表現(xiàn)出來了。在VRML環(huán)境中每一個(gè)節(jié)點(diǎn)必須分別在其坐標(biāo)軸 X,Y,Z中被提出。作為例子， 可能提及 的動(dòng)態(tài)節(jié)點(diǎn)可以看到 空氣污染的時(shí)間發(fā)展 變化 。 1. 坐標(biāo)系統(tǒng)：無論是 Matlab系統(tǒng)還是虛擬建模語言都是用右側(cè)的直角坐標(biāo)系，但是是 按照 像圖 3一樣的按 X軸旋轉(zhuǎn)。通過這些數(shù)據(jù)， 使用插值方法 查看捷克共和國(guó)的全境的數(shù)據(jù)，就可以在 某個(gè) 準(zhǔn)確的地點(diǎn)看到 當(dāng)?shù)?空氣污染的等級(jí)。s experiences with Virtual Reality Toolbox only. It is assumed that the presented model will be further developed in the future. As an example it is possible to mention the introduction of dynamical nodes to watch the time development of air pollution. Proposed applications include threedimensional models of air pollution and biomedical models based upon threedimensional magic resonance observations as well. In both these cases the visualization and animation is very useful. 空氣污染的虛擬現(xiàn)實(shí)模型 本文致力于 通過 Matlab系統(tǒng)的虛擬現(xiàn)實(shí)語言 及其 工具箱 來 描述 并 建模 。ciently to create animated three dimensional scenes driven from the Matlab and Simulink environment allowing signal or system modelling in the standard way. The paper summarises the initial author39。 3 現(xiàn)實(shí)數(shù)據(jù)的描述 捷克共和國(guó)的自動(dòng)監(jiān)控系統(tǒng)（ AIM）的大概 100多個(gè)測(cè)量站 會(huì) 定期 提供被選中的 大氣的組成成分的測(cè)量 數(shù)據(jù) ，檢驗(yàn)檢測(cè)污染物質(zhì)的濃度，每個(gè)站點(diǎn)每隔 30分鐘 檢測(cè)一次 ，持續(xù)一年。用任何文本編輯器編輯這個(gè) VRML (.wrl) 的程序都必須謹(jǐn)慎的按照下面的要求來創(chuàng)建 VRML文件。盡管虛擬現(xiàn)
