Arrow

class compas_view2.shapes.Arrow(position=[0, 0, 0], direction=[0, 0, 1], head_portion=0.3, head_width=0.1, body_width=0.02)[source]

Bases: Shape

A Arrow is defined by its location and direction vector.

Parameters:

• position (list of float or compas.geometry.Vector) – The start position of arrow

• direction (list of float or compas.geometry.Vector) – The height of the cone.

Attributes:

• head_portion (float) – The portion of head of the arrow

• head_width (float) – The head width relative to the length of arrow

• body_width (float) – The body width relative to the length of arrow

Examples

>>> from compas.geometry import Arrow
>>> arrow = Arrow([0, 0, 0], [0, 0, 1])
