摘要
建立了描述几何形体的数据结构，根据正轴测投影变换的性质和切削加工的特点，提出了动态图形的局部显示方法，实现了由前向后快速消隐算法。该方法已在工控机上实现。
The 3D real-time graphics simulation is one of the difficult techniques in computer nu-merical control(CNC).The data structure for describing a geometric body is constructed.According to the specific features of the CNC machining process and the properties of ortho-graphic projection, a local graphic display method for moving graphics is proposed and thefront-to-back visible-surface determination algorithm is achieved.As a result,the 3D real-time graphics simulation on an industrial computer is accomplished.
