【摘要】：隨著計(jì)算機(jī)圖形學(xué)技術(shù)的發(fā)展,目前對二維世界的研究已不能滿足人們的需求,進(jìn)而開始向三維領(lǐng)域擴(kuò)展。三維可視化技術(shù)即是利用計(jì)算機(jī)技術(shù),模擬三維世界中的物體,使其能夠表達(dá)三維物體的外觀,內(nèi)部構(gòu)造等復(fù)雜信息,并且使其具有實(shí)時(shí)交互的能力,實(shí)現(xiàn)對現(xiàn)實(shí)世界的真實(shí)再現(xiàn)。由于三維世界更加接近生活,人們對三維信息的需求與日俱增,三維可視化技術(shù)如雨后春筍般快速發(fā)展,已經(jīng)廣泛應(yīng)用于社會(huì)生活的各個(gè)領(lǐng)域,比如數(shù)字城市、軍事應(yīng)用、環(huán)境監(jiān)測、風(fēng)景區(qū)規(guī)劃、地質(zhì)體建模和礦山數(shù)字化建設(shè)、交通監(jiān)控、房地產(chǎn)開發(fā)、水文地質(zhì)活動(dòng)、醫(yī)療救助等。 另外三維可視化技術(shù)的優(yōu)勢在很多行業(yè),科研領(lǐng)域,工程項(xiàng)目上也都得到的體現(xiàn),例如在地質(zhì)行業(yè)的應(yīng)用,三維可視化技術(shù)解決了原始地質(zhì)體只能在紙質(zhì)圖紙上繪制的缺點(diǎn),將地質(zhì)體模型以三維直觀的形態(tài)展現(xiàn),很好的實(shí)現(xiàn)數(shù)據(jù)共享,為數(shù)字礦山的建設(shè)提供了幫助。在航空領(lǐng)域,三維可視化技術(shù)強(qiáng)大的視覺沖擊力帶領(lǐng)大家遨游了太空,就像置身于太空中一樣,在仿真技術(shù)方面的應(yīng)用,可為醫(yī)學(xué)手術(shù)實(shí)施、機(jī)械制造加工、礦物開采加工、水利設(shè)施建設(shè)等提供一定的決策作用。也就是說,三維可視化技術(shù)的發(fā)展,已給人們帶來了更多的驚喜,對三維可視化的研究有著非常重要的意義。 構(gòu)建數(shù)據(jù)模型從計(jì)算機(jī)學(xué)科出發(fā),已經(jīng)滲透到各個(gè)學(xué)科當(dāng)中。在地理學(xué)、地質(zhì)學(xué)、測繪學(xué)、海洋學(xué)、建筑學(xué)、生物醫(yī)學(xué)等學(xué)科中都逐漸開始應(yīng)用建模技術(shù),而且為這些學(xué)科的科學(xué)研究提供了極其有用的幫助,在一定程度上促進(jìn)了這些學(xué)科的發(fā)展。 地質(zhì)行業(yè)作為一門特殊的行業(yè),有它一定的艱苦性,我國歷史悠久,地層年代久遠(yuǎn),地質(zhì)條件因地區(qū)性存在很大差異。地質(zhì)情況掌握的好壞直接關(guān)系到煤礦安全生產(chǎn),房屋、隧道、橋梁安全建設(shè)等等方面,所以地質(zhì)行業(yè)的發(fā)展也間接關(guān)系到民生工程的建設(shè)。地質(zhì)體的建模和三維可視化技術(shù)既是在科技飛速發(fā)展的今天應(yīng)運(yùn)而生,近些年來已成為學(xué)者們研究的熱點(diǎn),國內(nèi)外的學(xué)者在地質(zhì)體數(shù)據(jù)建模和三維可視化領(lǐng)域也取得了一定的成就,但是學(xué)術(shù)是沒有頂峰的,需要地質(zhì)學(xué)者們不斷攀巖。本論文就單-多z值地質(zhì)體的混合建模和三維可視化,空間分析做了研究和討論,主要技術(shù)路線是：使用c++開發(fā)語言,在VC++6.0中的MFC可視化開發(fā)框架下,結(jié)合圖形庫OpenGL做地質(zhì)體的統(tǒng)一建模及三維可視化,空間分析研究。首先將地質(zhì)勘探法獲得的鉆孔數(shù)據(jù)整理存儲(chǔ),插值加密得到地質(zhì)體建模的源數(shù)據(jù),然后在計(jì)算機(jī)上編寫代碼,結(jié)合OpenGL圖形庫繪制地質(zhì)體面元,模擬出單-多Z值地質(zhì)體的面模型,繼而根據(jù)地質(zhì)體面元z值與體元Z值大小的比較結(jié)果,設(shè)置算法構(gòu)建單,多Z值地質(zhì)體的體模型,在計(jì)算機(jī)上三維可視化表示。在地質(zhì)體統(tǒng)一模型構(gòu)建的基礎(chǔ)上再實(shí)現(xiàn)地質(zhì)體的空間分析功能,使得地質(zhì)體模型不是單一的而是具有空間分析功能的模型。關(guān)鍵措施如下：(1)鉆孔數(shù)據(jù)的三維坐標(biāo)的規(guī)整(2)插值獲取加密的鉆孔數(shù)據(jù),使其足以構(gòu)建精確的地質(zhì)體數(shù)據(jù)模型(3)利用c++面向?qū)ο蟮拈_發(fā)特點(diǎn),編寫程序?qū)崿F(xiàn)單,多z值地質(zhì)體的統(tǒng)一建模和三維可視化(4)為可視化的地質(zhì)體模型貼紋理使其更加真實(shí)和直觀(5)編寫程序?qū)崿F(xiàn)地質(zhì)體模型的剖面圖,使得地質(zhì)體內(nèi)部結(jié)構(gòu)能得以體現(xiàn)(6)提高可視化程度添加屬性查詢,空間量算,三維坐標(biāo)查詢。
[Abstract]:With the development of computer graphics technology, the current research on the two-dimensional world already cannot satisfy people's needs, and then began to expand the field of 3D. 3D visualization technology is the use of computer technology, simulation of 3D objects in the world, making it possible to express 3D object appearance, internal structure of complex information, and it has the ability of real-time interaction, achieve a true representation of the real world. The 3D world closer to life, people demand for three-dimensional information visualization techniques such as bamboo shoots after a spring rain grow with each passing day, like rapid development, has been widely used in various fields of social life, such as digital city, military applications, environmental monitoring, scenic area planning, digital construction, geology mine body modeling and traffic monitoring, real estate development, hydrogeology, medical assistance and so on.
In addition to the field of scientific research of 3D visualization technology advantage in many industries, projects have also been reflected, for example in the application of geological industry, 3D visualization technology to solve the original geological body can only draw on paper drawing on the shortcomings of the geological model to show three-dimensional shape, to achieve a good data sharing provides help for the construction of digital mine. In the field of aviation, the visual impact of 3D visualization technology powerful lead us to visit the space, like space, used in simulation technology, can be implemented for medical surgery, mechanical manufacturing, mineral processing, and provide decision a certain role in the construction of water conservancy facilities etc. that is to say, the development of 3D visualization technology, has brought more surprises, has a very important significance to the study of 3D visualization.
Starting from the construction of computer science data model, has penetrated into various disciplines. In geography, geology, topography, oceanography, architecture, biomedical and other disciplines are gradually began to use modeling technology, and provides useful help for scientific research in these disciplines, to a certain extent, promoted the development of these disciplines.
The geological industry as a special industry, it is difficult to some extent, China has a long history, stratigraphic age, geological conditions for different regional geological conditions. Master is directly related to the coal mine production safety, housing, tunnel, bridge construction safety and so on, so the development of geological industry also indirectly to the construction of livelihood projects. Geological modeling and 3D visualization technology is in the rapid development of science and technology today emerged in recent years has become the focus of scholars, domestic and foreign scholars have made some achievements in geological data modeling and 3D visual field, but there is no academic peak, need geological scholars continue to rock climbing. The single - Z hybrid modeling and 3D visualization, spatial analysis to do the research and discussion, the main technical route is: using c++ The development of language, visual MFC development framework in VC++6.0, unified modeling and 3D visualization with OpenGL graphics library to do geological research. Firstly, the spatial analysis of geological exploration drilling data obtained by sorting storage, interpolation source data obtained geological modeling, and then write code on the computer, with OpenGL graphic library drawing geological decent yuan, simulate the single surface model of multi Z value of geological bodies, and then according to the geological element Z value comparison results of decent size and element Z value setting algorithm to construct single and multi Z value model of the geological body, said the computer 3D visualization. Based on establishing a unified model of geological body on the implementation of geological spatial analysis function, the geological model is not single but has the function of spatial analysis model. The key measures are as follows: (1) the 3D coordinates of borehole data. The interpolation (2) Get bored of data encryption, so it can build accurate geological data model (3) using the development characteristics of c++ object oriented programming, single, multi Z unified modeling and 3D visualization of geological body (4) for geological model visualization of the texture to make it more real and intuitive writing (5) profile of program of the geological model, the internal structure of the geological body can be reflected in (6) to improve the visualization of the add attribute query, spatial measurement, three-dimensional coordinates query.
