The triangular elements and area coordinates are used to solve the numeric solution.
应用三角剖分、引入面积坐标来求出方程的近似解。
First, scan the reflectivity data in the immediate area around the detection coordinates, allowing for precipitation front movement from any direction.
首先,扫描检测坐标周围紧接区域中的反射率数据,允许降水前锋移向任意方向。
With these pixel coordinates, we can draw lines emanating from the the points, recolor them, connect them, fill the surrounding area with color, or anything else GD can do.
使用这些像素坐标,我们可以绘制以这些点为起点的直线,重新设定直线的颜色、连接直线、用颜色填充周围的区域或者 GD 可以执行的任何其他操作。
