arc_swap_positions

Function

arc_swap_positions(
    state_1: State,
    state_2: State,
    t_start: float,
    t_end: float,
    clockwise: bool = True,
    arc_radius: Optional[float] = None,
    easing: Optional[Dict[str, Callable[[float], float]]] = None
) -> Tuple[List[KeyState], List[KeyState]]

Swaps the positions of two elements along arc paths.

Both elements travel along parallel arcs in the same direction to avoid collision. The arc radius must be at least half the distance between points.

Parameters

state_1: The base State of the first element.
state_2: The base State of the second element.
t_start: Start time of the swap.
t_end: End time of the swap.
clockwise: Arc direction (default True).
arc_radius: Arc radius. If None, defaults to distance between points.
easing: Optional easing dict for position transitions.

Returns

Tuple of (keystates_for_elem1, keystates_for_elem2)

Examples

ks1, ks2 = arc_swap_positions(circle1, square2, t_start=0.3, t_end=0.8)
    elem1 = VElement().segment(ks1)
    elem2 = VElement().segment(ks2)
