平面立体轴测形态图计算理论和方法

Theory and onethonds for Computering the aspect graph of planar objects

以平面立体的投影图中出现的奇异性为基础 ,论述了平面立体所有视觉事件类型及其对应的投影空间的划分 ,指出平面立体的投影空间划分的关键是立体上两个不在同一多边形面上的顶点和棱线以及每三条空间相互交叉的棱线之间发生的奇异性 ,分析了三种类型分割平 (曲 )面 ,给出了平面立体形态图和特征视图的求解方法 。

We have developed algorithm for computering the aspect graph for planer.A complet catolog of the visual events.that occur for planar objests is presented.we have also described how the structure of the objects is reflexedin the locus of accidental view-point.
