摘　　要：针对传统博物馆文物数据可视化存在交互效果不佳的问题,提出以陕西省历史博物馆为研究对象,构建一个基于多点触控技术的三维虚拟博物馆设计与漫游系统。首先,采用二维形式进行博物馆三维设计;然后通过多点触控屏幕展示博物馆三维设计效果;最后采用基于变分圆形树图实现层次化数据交互可视化,以提升文物数据空间利用率,并采用层次切换交互技术实现文物数据可视化交互。实验结果表明,对于EOL数据的前6层圆布局测试中,对比于传统的圆形树图和加权能量算法,提出的变分圆形树图的空间利用率提升了4%~52%,且将提出多点触控技术应用到三维虚拟博物馆中可实现文物数据的可视化交互。由此说明,提出的算法可有效提升虚拟博物馆的空间利用率,设计的基于多点触控技术的层次化文物数据可视化交互系统具备一定的可行性。In view of the problem of poor interaction effect in the data visualization of cultural relics in traditional museums,it is proposed to build a 3 D virtual museum design and roaming system based on multi-touch technology based on Shaanxi Provincial History Museum as the research object.First,the 3 D design is conducted in two-dimensional form;then the 3 D design effect of museum is displayed through multi-touch screen;finally,adopt hierarchical data interactive visualization based on variable circular tree map to improve the space utilization rate of cultural relic data,and adopt the hierarchical switching interactive technology to realize the visual interaction of cultural relic data.The experimental results show that in the first 6 layers of the circle layout test of EOL data,compared with the traditional circular tree map and weighted energy algorithm,the space utilization of the variational circular tree map increased by 4%~52%,and the proposed multi-touch technology was applied to the three-dimensional virtual museum to realize the visual interaction of cultural relics data.This shows that the proposed algorithm can effectively improve the space utilization rate of virtual museums,and the designed hierarchical cultural relic data visual interactive system based on multi-touch technology has certain feasibility.
