从点生长

限定名称: manim.animation.growing.GrowFromPoint

class GrowFromPoint(mobject=None, *args, use_override=True, **kwargs)

基础类：Transform

通过从一个点生长来介绍一个Mobject。

Parameters:

• mobject (Mobject) – 要引入的mobjects。

• 点 (np.ndarray) – 物体生长的起点。

• point_color (str) – 物体在增长到其完整大小之前的初始颜色。留空以匹配物体的颜色。

示例

示例：GrowFromPointExample

from manim import *

class GrowFromPointExample(Scene):
    def construct(self):
        dot = Dot(3 * UR, color=GREEN)
        squares = [Square() for _ in range(4)]
        VGroup(*squares).set_x(0).arrange(buff=1)
        self.add(dot)
        self.play(GrowFromPoint(squares[0], ORIGIN))
        self.play(GrowFromPoint(squares[1], [-2, 2, 0]))
        self.play(GrowFromPoint(squares[2], [3, -2, 0], RED))
        self.play(GrowFromPoint(squares[3], dot, dot.get_color()))
