摘要
阐述了板料成形数值模拟前置处理软件中人机交互的实现。详细地论述了图形的几何变换 ,即平移、旋转和缩放的技术 ,以及基于OpenGL拾取机制的网格节点和单元拾取方法。最后讨论了在软件的实现中面向对象技术的运用。
In this paper, a method realizing the interaction between user and computer in the prior processor of numerical simulation of sheet forming is introduced. Transformation of the graphic such as translation, rotation and scale is detailed,The method of picking up nodes and elements on the surface of sheet is discussed. Later, the application of objectoriented technology is presented.
