fibomat.shapes.hollow_arc_spline module

class fibomat.shapes.hollow_arc_spline.HollowArcSpline(boundary: ArcSpline, holes: Sequence[ArcSpline] | None = None, description: str | None = None, disable_checks=False)

Bases: Shape

__init__(boundary: ArcSpline, holes: Sequence[ArcSpline] | None = None, description: str | None = None, disable_checks=False)

Args:

description (str, optional): description

property boundary: ArcSpline

property holes: List[ArcSpline]

property is_closed: bool

bool: True if shape is closes. This property should not be defined for 0-dim shapes

Access:

get

contains(pos: Vector | Iterable[float]) → bool

Returns True if pos is contained in shape

Args:

pos (VectorLike): point to be tested

Returns:

bool

property center: Vector

center of the (geometric) object

Access:

get

Returns:

Any

property bounding_box: BoundingBox

BoundingBox: bounding box of transformable

Access:

get

clone() → T

Create a deepcopy of the object.

Returns:

Describable

property description: str | None

Description str.

Access:

get

Returns:

Optional[str]

mirrored(mirror_plane: VectorT) → SelfT

Return a mirrored object mirrored about mirror_plane.

Args:

mirror_plane (VectorLike): mirror plane to be used.

Returns:

TransformableBase

property pivot: VectorT

Origin of the (geometric) object. If origin is set to None, Transformable.center will be returned.

Pivot must be set to a callable function without parameters.

transformable_obj = ...
transformable_obj.pivot = lambda: return Vector(1, 2)
print(transformable_obj.pivot)  # will print Vector(1, 2)

Access:

get/set

Returns:

Vector

rotated(theta: float, origin: VectorT | str | None = None) → SelfT

Return a rotated copy around origin with angle theta in math. positive direction (counterclockwise).

Args:

theta (float): rotation angle in rad origin (Optional[Union[linalg.VectorLike, str]], optional):

origin of rotation. If not set, (0,0) is used as origin. If origin == ‘center’, the Transformable.center of the object will be used. The same applies for the case that origin == ‘origin’ with the Transformable.origin property. Default to None.

Returns:

TransformableBase

scaled(fac: float, origin: VectorT | str | None = None) → SelfT

Return a scale object homogeneously about origin with factor s.

Args:

fac (float): rotation angle in rad origin (Optional[Union[linalg.VectorLike, str]], optional):

origin of rotation. If not set, (0,0) is used as origin. If origin == ‘center’, the Transformable.center of the object will be used. The same applies for the case that origin == ‘origin’ with the Transformable.origin property. Default to None.

Returns:

TransformableBase

transformed(transformations: _TransformationBuilder[VectorT]) → SelfT

Return a transformed object. the transformation can be build by the following functions:

• translate()

• rotate()

• scale()

• mirror()

E.g.

transformable_obj.transform(translate([1, 2]) | rotate(np.pi/3) | mirror([3,4])

Args:

transformations (_TransformationBuilder): transformation

Returns:

TransformableBase

translated(trans_vec: VectorT) → SelfT

Return a translated copy of the object by trans_vec.

Args:

trans_vec (VectorLike): translation vector

Returns:

TransformableBase

translated_to(pos: VectorT) → SelfT

Return a translated copy of the object so that self.pivot == pos

Args:

pos: new position of object

Returns:

TransformableBase

with_changed_description(new_descr: str) → T

Clones the object and set the description to new_descr.

Args:

new_descr: new description

Returns:

Describable
