rotation

重要

如果你想要实现旋转效果，请不要尝试直接使用 self.play(item.anim.points.rotate(...))， 因为这只是在当前和结果之间进行 MethodTransform ，并无旋转效果

实现旋转效果请使用下方给出的 Rotate 和 Rotating

class janim.anims.rotation.Rotate(item: Item, angle: float, *, axis: Vect = array([0., 0., 1.]), about_point: Vect | None = None, about_edge: Vect = array([0., 0., 0.]), root_only: bool = False, absolute: bool = True, **kwargs)

基类：DataUpdater

旋转，默认对角度进行平滑插值

• 参数和旋转基本一致

• absolute 参数是为了兼容摄像机物件，对于非摄像机物件该参数无效

RotateExample

from janim.imports import *

class RotateExample(Timeline):
    def construct(self):
        square = Square(side_length=4).show()

        self.play(
            Rotate(
                square,
                PI / 4,
                duration=2
            )
        )
        self.forward(0.3)
        self.play(
            Rotate(
                square,
                PI,
                axis=RIGHT,
                duration=2,
            )
        )
        self.forward(0.3)

class janim.anims.rotation.Rotating(item: ~janim.items.points.Points, angle: float, *, rate_func=<function linear>, **kwargs)

基类：Rotate

旋转，默认对角度进行线性插值

RotatingExample

from janim.imports import *

class RotatingExample(Timeline):
    def construct(self):
        square = Square(side_length=4).show()

        self.play(
            Rotating(
                square,
                PI / 4,
                duration=2
            )
        )
        self.forward(0.3)
        self.play(
            Rotating(
                square,
                PI,
                axis=RIGHT,
                duration=2,
            )
        )
        self.forward(0.3)
