包含两个算法，用于旋转模糊的模拟。一种是直接根据模糊过程原理进行模糊，一种是将其变换到旋转圆周上进行直线模糊，再变换回来。-Consists of two algorithms, used to rotate the fuzzy simulation.Directly according to the principle of fuzzy process is a kind of fuzzy, one kind is to transform it to rotate on the circumference of linear fuzzy, transform to come back again.
