摘要
有效的生成三维虚拟场景的2D导航地图,是解决虚拟漫游迷失感、完善虚拟漫游的一个重要问题。基于MapXtreme-Java电子地图开发平台,提出一种虚拟漫游2D导航电子地图的建立方法。通过透视投影法获取场景的平面图,利用MapXtreme for Java在平面图上进行地理数据的添加和扩充,建立平面区域和三维场景坐标的映射关系,支持三维场景与2D地图的互响应。该方法能方便操作人员快速、简洁的建立导航图,指导操作者完成漫游任务,提高了漫游系统的人机交互能力。
Getting 2D navigational map of 3D virtual scene effectively is an important question of solving astray in the virtual wandering .Based on MapXtremeJava digital map development platform,a method of creating 2D navigational digital map is proposed. The perspective projection is used to obtain plan scene of 3D scene and throuhg MapXtreme for Java geographical data is added and expanded. The dynamic response between 2D digital map and 3D VR is supported by building mapping relation between planar region and 3D scene coordinates.This way of creating 2-D navigational map is effective and simple,it can improve the ability of humancomputer interaction of wandering system.
