geometry data is modeled as a regular grid, and texture comes from the remote sense or satellite images 地形幾何數(shù)據(jù)來(lái)源于數(shù)字高程模型(dem),紋理數(shù)據(jù)來(lái)源于衛(wèi)星和遙感圖象。
and the necessary, feasibility and common structure of dynamic data exchange format are expatiated, which is used to manage the exchange of geometry data 并對(duì)其中針對(duì)實(shí)時(shí)處理圖形數(shù)據(jù)交互而提出的動(dòng)態(tài)數(shù)據(jù)格式的必要性和可行性及其一般結(jié)構(gòu)進(jìn)行了研究。
research shows that retained-mode systems can do belonging judgement more effectively by using its capability of handling geometry data to divide models into small units 發(fā)現(xiàn)保留模式并行繪制系統(tǒng)可以利用對(duì)圖形數(shù)據(jù)的控制能力對(duì)模型進(jìn)行剖分,進(jìn)行更加高效的歸屬判斷。
the commercial cad / cam software ug n is used to set up the flow entity model, and it is imputed into the finite element analysis software ansys via the universal geometry data standard 通過(guò)商業(yè)化的cadacm軟件ug為基礎(chǔ)構(gòu)建氣道流體實(shí)體模型,并利用通用的幾何標(biāo)準(zhǔn)將模型導(dǎo)入到有限元分析軟件ansys中。
in this paper, i designed some table to store geometry and non-geometry data according to the analysis i did on the data to be handled . mose of all, i succeeded in putting these data illto corresponding tables 本文在對(duì)要處理的數(shù)據(jù)進(jìn)行了詳細(xì)分析的基礎(chǔ)上設(shè)計(jì)了存儲(chǔ)幾何和非幾何信息的數(shù)據(jù)庫(kù)表,并且完成了數(shù)據(jù)信息存入數(shù)據(jù)庫(kù)和提取數(shù)據(jù)的開(kāi)發(fā)工作。
