摘要
通过提取视觉变量中能产生虚实感、远近感以及时空跨越感的变量,将时间属性融合到地图符号中,由此提出了三维时态建模的方法。该方法能够形象、直观地描述空间对象的时间信息,丰富三维模型的载负量。
Combined both the merits of 3D modeling and the development of temporal map, this paper extracted a couple of factors from visual variables, such as virtual sense, overall perspective, sense of space and time span, and so forth. Meanwhile, the paper incorporated time attribute into the map symbol, which proposed the method to build spatio-temporal model. To describe the temporal information of those space objects, this method can be visual and intuitionistic. It can enrich the information load of 3D model at the same time.
