fibomat.shapes.polyline module¶

Provide the Polyline class.

class fibomat.shapes.polyline.Polyline(points: List[Union[fibomat.linalg.vectors.vector.Vector, Iterable[float]]], description: Optional[str] = None, _closed: bool = False)[source]¶

Bases: fibomat.linalg.transformables.transformable_base.TransformableBase[fibomat.linalg.vectors.vector.Vector, float, fibomat.linalg.boundingboxes.boundingbox.BoundingBox], abc.ABC

__init__(points: List[Union[fibomat.linalg.vectors.vector.Vector, Iterable[float]]], description: Optional[str] = None, _closed: bool = False)[source]¶

Args:: points (VectorArrayLike): polyline points description (str, optional): description

to_arc_spline() → fibomat.shapes.arc_spline.ArcSpline[source]¶

Transform shape to ArcSpline.

Returns:: ArcSpline

property points: numpy.ndarray¶

Polyline points.

Access:: get
Returns:: np.ndarray

property n_points: int¶

Number of points.

Access:: get
Returns:: int

property bounding_box: fibomat.linalg.boundingboxes.boundingbox.BoundingBox¶

BoundingBox: bounding box of transformable

Access:: get

property is_closed: bool¶

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

Access:: get

property center: fibomat.linalg.vectors.vector.Vector¶

center of the (geometric) object

Access:: get
Returns:: Any

clone() → fibomat.describable.T¶

Create a deepcopy of the object.

Returns:: Describable

property description: Optional[str]¶

Description str.

Access:: get
Returns:: Optional[str]

mirrored(mirror_plane: fibomat.linalg.transformables.transformable_base.VectorT) → fibomat.linalg.transformables.transformable_base.SelfT¶

Return a mirrored object mirrored about mirror_plane.

Args:: mirror_plane (VectorLike): mirror plane to be used.
Returns:: TransformableBase

property pivot: fibomat.linalg.transformables.transformable_base.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: Optional[Union[fibomat.linalg.transformables.transformable_base.VectorT, str]] = None) → fibomat.linalg.transformables.transformable_base.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: Optional[Union[fibomat.linalg.transformables.transformable_base.VectorT, str]] = None) → fibomat.linalg.transformables.transformable_base.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: fibomat.linalg.transformables.transformation_builder._TransformationBuilder[fibomat.linalg.transformables.transformable_base.VectorT]) → fibomat.linalg.transformables.transformable_base.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: fibomat.linalg.transformables.transformable_base.VectorT) → fibomat.linalg.transformables.transformable_base.SelfT¶

Return a translated copy of the object by trans_vec.

Args:: trans_vec (VectorLike): translation vector
Returns:: TransformableBase

translated_to(pos: fibomat.linalg.transformables.transformable_base.VectorT) → fibomat.linalg.transformables.transformable_base.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) → fibomat.describable.T¶

Clones the object and set the description to new_descr.

Args:: new_descr: new description
Returns:: Describable
