| 摘 要： | 等值线追踪是绘制等值线图的关键,好的追踪算法可使图形更精确,同时节省大量时间。本文在传统追踪算法的基础上,提出了一种新的追踪等值线的方法——搜索圆法,并详细介绍了该方法的追踪步骤。该方法可实现快速分块扫描,大大提高追踪效率,可靠性好。

| Abstract: | Isoline Tracing is the key in the course of drawing isoline map, Good tracing arithmetic may draw more precise than before, at the same time, it may economize quantities of time.The article puts forward a new tracing arithmetic-search-circle method based on traditional arithmetic and introduces particularly the tracing steps. The search-circle method can implement quickly part-scan and can heighten largely tracing efficiency. What is more, the method has good reliability. |
