摘要
对文化遗产的虚拟三维实时浏览成为文化遗产展示与宣传的重要手段与主要途径。随着三维激光扫描技术等数据获取技术的发展,用以表达文化遗产的几何、纹理数据呈几何倍数增长,数据的管理与绘制的调度成为重点研究内容。为此,本研究主要介绍数据的分块技术、空间索引技术与绘制加速技术在交河故城三维模型实时绘制中的应用,通过有效地组织交河故城遗址的三维数据,并在浏览系统中应用绘制加速技术实现在整个范围内的实时高效浏览。
The real - time rendering of 3D of the Jiaohe Ruins is a key method to broadcast charisma of cultural heritage. With the rapid developing of the 3 D scanning technology in data acquiring, the quantity of gemetry and texture data of the heritage buildings grows geometrically. The data management becomes a key issue. This paper introduces the block technology of data, spatial index and accelerating strategies in real time rendering the Jiaohe Ruins 3D model. The 3D data of Jiaohe Ruins have be managed by these methods , and achieved real- time effi- ciently browsing in the three- dimensional system.
