Point Cloud Mobject¶
PMobject¶
-
class
manimlib.mobject.types.point_cloud_mobject.PMobject(**kwargs)¶ 点物件
-
add_points(points: npt.ArrayLike, rgbas: np.ndarray | None = None, color: ManimColor | None = None, opacity: float | None = None)¶ 添加点，点必须是若干个三维坐标，即 Nx3 的数组
-
point_from_proportion(alpha: float) → numpy.ndarray¶ 获取点集上百分比为 alpha 的最接近的点
-
pointwise_become_partial(pmobject: manimlib.mobject.types.point_cloud_mobject.PMobject, a: float, b: float)¶ 获取点集上百分比从 a 到 b 的点
-
resize_points(size: int, resize_func: Callable[[np.ndarray, int], np.ndarray] = <function resize_array>)¶ 重置锚点数组大小
-
set_color_by_gradient(*colors: ManimColor)¶ 渐变染色
-
set_points(points: npt.ArrayLike)¶ 设置锚点
-
sort_points(function: Callable[[np.ndarray]] = <function PMobject.<lambda>>)¶ 按照传入的函数对点进行排序，函数接受一个 三维 坐标，返回一个数值
-
PGroup¶
-
class
manimlib.mobject.types.point_cloud_mobject.PGroup(*pmobs: manimlib.mobject.types.point_cloud_mobject.PMobject, **kwargs)¶ 点集组合
