摘要
在VRML文件中,Viewpoint节点是通过指定旋转轴和旋转角定义的,用户很难给出其适当的参数.因此提出一种方法,定义了一个可视化界面,用户可以通过其习惯的思维及交互的方式获取定义Viewpoint节点所需的参数,以自动生成观看场景的视角.
In VRML file, Viewpoint node is defined by revolving axis and revolving angle appointed. It is difficult proper parameters. A method is provided by defining a visual interface, by which user can get needed parameters for defining viewpoint node by alternate means using his used thinking in order to create angle of view for looking at the scene automatically.
