PEASY 魔法飞球2 的计算器源码，支持动态捕获风向角度。自动推杆，61杆，爆球，一杆进洞计算

matlab画格点风向杆和风羽的函数，在气象绘图中使用较多而且方便-matlab draw grid wind direction and wind feather rod function more in the weather and easy to use drawing

flex实现的风向杆，有三角、全长直线、半长直线，给定风向和风速就可在指定位置画出风向标(Flex implements the wind bar with a triangle, a full length straight line and a half long straight line, and a wind vane can be drawn at a given position given the wind direction and wind speed)
