微型计算机在我国科学技术的各个领域內正广泛地应用。但用于图形显示方面尚在摸索中,本文为了屏幕显示图形,设计了若干绘图基本软件,並用以绘制零件三视图。解决了微型计算机APPLEⅡ型与FWX4675绘图机同时显示与同时绘图的问题。並对在屏幕上绘制三维图形及其消隐处理作了探讨。
Microcomputers are widely used in various fields of science and technology in our country. But for the graphical display is still groping, this article for the screen display graphics, design a number of basic drawing software, and used to draw three parts view. Solve the microcomputer APPLE Ⅱ type and FWX4675 plotter simultaneous display and simultaneous drawing problems. And on the screen to draw three-dimensional graphics and its blanking treatment were discussed.
