Set Curvature

class SetCurvature(mobject: Mobject, curvature: float, run_time=3, apply_function_kwargs: Dict[str, Any] | None = None, **kwargs)

An animation that changes the curvature of the hyperbolic plane that an object lives in.

Note

Only affects the object but not the other objects associated with the corresponding hyperbolic plane.

Examples
