ApplyWave¶
-
class
manimlib.animation.indication.ApplyWave(mobject: Mobject, **kwargs)¶ homotopy 是一个从 (x, y, z, t) 到 (x’, y’, z’) 的函数。 t 的取值范围是 [0, 1]， 让 mobject 根据 homotopy 计算的每个点坐标进行变换。 例子中 t = 0 时 mob 是边长为 0 的正方形， t = 1 时是边长为 2 的正方形。 与 Transform 类似，区别在于 Transform 锚点运动轨迹是直线， Homotopy 锚点运动轨迹是根据传入的 homotopy 计算的。

mobjects = VGroup(
Circle(),
Circle(fill_opacity=1),
Text("Text").scale(2)
