In order to obtain the 2-D projection data, a longitudinal traveling workbench controlled by computer is set up to realize linebylinescan.
为了得到完整的螺纹牙型数据,建立了计算机控制的纵向工作台,可以实现对螺纹投影的逐行扫描。

The different information is implemented to clear and steadily display by using of time-shared display with linebylinescan ning and interlaced scanning in a raster picture.
一幅光栅图形中的逐行扫描与隔行扫描分时完成并使不同信息获得清晰稳定的显示效果。
