【摘要】：近些年來(lái),隨著計(jì)算機(jī)與計(jì)算技術(shù)的飛速發(fā)展,數(shù)據(jù)觀測(cè)和采集儀器的進(jìn)步,生成了大量的氣象數(shù)據(jù),怎樣充分使用這些數(shù)據(jù)進(jìn)行更好的氣象預(yù)報(bào)是氣象工作者的一個(gè)非常具有挑戰(zhàn)性的課題。將科學(xué)數(shù)據(jù)可視化的技術(shù)應(yīng)用到氣象領(lǐng)域,使得原本復(fù)雜、海量、晦澀的數(shù)據(jù)轉(zhuǎn)變成直觀的二維和三維可視化結(jié)果,有效幫助氣象工作者分析氣象數(shù)據(jù)和在短時(shí)間做出準(zhǔn)確的判斷。因此開發(fā)出一款面向氣象數(shù)據(jù)的可視化平臺(tái)具有極大的價(jià)值和意義。 本文以O(shè)penGL和GLSL為基礎(chǔ),Qt為開發(fā)框架,開發(fā)了一個(gè)結(jié)合地理信息的三維數(shù)值大氣數(shù)據(jù)可視化平臺(tái)。平臺(tái)的基礎(chǔ)是基于地理信息的三維虛擬環(huán)境的快速構(gòu)建和建模,在此之上的三維數(shù)值大氣數(shù)據(jù)的可視化提供了全球尺度的大氣信息(如溫度、濕度、風(fēng)場(chǎng)、云等)的直觀呈現(xiàn)。此外,平臺(tái)還支持氣象數(shù)據(jù)的常規(guī)處理和操作,包括數(shù)據(jù)等值線和等值面的抽取和繪制,三維數(shù)據(jù)的直接體繪制,切面繪制,多種不同繪制物體的混合繪制以及矢量場(chǎng)數(shù)據(jù)的各種繪制方法。通過用戶的一些交互可以選取對(duì)全局或者局部數(shù)據(jù)操作,為用戶提供了良好的交互方式。 本系統(tǒng)基于模塊和插件式的設(shè)計(jì)和開發(fā),支持多平臺(tái)且易于擴(kuò)展,為未來(lái)工作打下堅(jiān)實(shí)的基礎(chǔ)。
[Abstract]:In recent years, with the rapid development of computer and computing technology, data collection and observation instrument progress, generating a large number of meteorological data, meteorological forecast how to make full use of these data better is a very challenging topic. Meteorologists will scientific data visualization technology applied to the field of meteorology, making the complex, massive, obscure data into intuitive 2D and 3D visualization results, effectively help meteorologists meteorological data analysis and make accurate judgment in a short time. Therefore, the development has a great value and significance of a visualization platform for meteorological data.
This paper is based on OpenGL and GLSL, Qt development framework, the development of a GIS 3D numerical atmospheric data visualization platform. The platform is based on 3D virtual environment of geographic information, quick construction and modeling based on visualization of 3D numerical atmospheric data above provide information (such as global scale atmospheric temperature humidity, wind, clouds, etc.) visual presentation. In addition, the platform also supports the conventional treatment and operation of meteorological data, including data extraction contour and isosurface rendering and direct volume rendering, 3D data, section drawing, different drawing objects mixed rendering and vector field data through various rendering methods. Some user interaction can be selected for the global or local data operation, provides a good interactive way for users.
The design and development of the system module and plug-in based on multi platform and easy to expand, lay a solid foundation for future work.
