摘要
设计了虚拟维修系统局部坐标系与整体坐标系的坐标变换矩阵,给出了不同对象间进行坐标变换的方法;设计了TPO视点变换函数,能够方便地控制视点位置和方向;提出了一种节点逻辑分离算法,能够在系统运行状态下解除节点间的隶属关系,解决已分离节点与父节点的运动关联问题,导航方式合理、交互操作逼真.
The transformation matrix between the local coordinate and the world coordinate of virtual maintenance system is designed, and the methods for coordinate transformation among different objects are given in this article. A viewpoint transformation function is designed, and the location and direction of viewpoint can be controlled conveniently. A nodes logical detach algorithm is put forward. It can free the relationship of administrative subordination between nodes, and the problem of motion interconnection between the detached node and the father node is solved. The model of navigation is reasonable and the interactive operation is really true.
