| 摘 要： | 随着计算机软硬件技术和三维可视化技术的快速发展,二维平面电子地图正在向直观、形象的三维电子地图方向过渡,而原来的二维地图符号已难以满足三维场景逼真性的要求,它必然要求与之配套的三维符号理论和技术的产生。由于三维符号如何构成及怎样标注尚无标准可遵循,在对三维符号的构成、分类及建模方法进行分析的基础上,提出了实体模型符号的两种建模方法,实验表明它们切实可行,能较好地表达三维实体模型。 |
| 关 键 词： | 电子地图 三维符号 三维实体模型符号 三维建模 |

| Abstract: | With the rapid development of the technologies of computer hardware and three-dimensional visualization,two-dimension electronic map are gradually developed into the visible and direct visual three-dimension electronic map.While the original 2D cartographic symbols cannot meet the 3D circumstance realistic expectations,which requires the corresponding 3D symbols technology.As it is unknown what constitute the 3D cartographic symbols and how to plot them,this paper makes an analysis on the form and classification of 3D symbols and brings forward two modeling methods of entitative model symbols.The experiments show that they are well feasible in expressing the 3D entitative symbols. |
| Keywords: | electronic map 3D symbol 3D entitative model symbols 3D modeling |
