Arrow3D#

Qualified name: manim.mobject.three\_d.three\_dimensions.Arrow3D

class Arrow3D(start=array([- 1., 0., 0.]), end=array([1., 0., 0.]), thickness=0.02, height=0.3, base_radius=0.08, color=ManimColor('#FFFFFF'), **kwargs)[source]#

Bases: Line3D

An arrow made out of a cylindrical line and a conical tip.

Parameters:

  • start (np.ndarray) – The start position of the arrow.

  • end (np.ndarray) – The end position of the arrow.

  • thickness (float) – The thickness of the arrow.

  • height (float) – The height of the conical tip.

  • base_radius (float) – The base radius of the conical tip.

  • color (ParsableManimColor) – The color of the arrow.
