arrows in space as the items of a scene3d, a line for the shaft and a cone for the head; what quiver3d and quiver of 3D grains draw

Syntax

items = arrows3d(P, D)

Arrows from the points P along D.

items = arrows3d(P, D, color='r', antipodal=True)

Red segments pointing both ways.

Description

Every arrow runs from its point P to P + D, its head a cone headSize of its length long. Arrows with a zero or non finite D are left out. The items are added to a scene with scene3d.add, which the renderer of a 3D figure draws.

Input

P array (n, 3), the starting points
D array (n, 3), the arrows

Keywords

keyword default description
color (0.0, 0.0, 1.0) one colour for all arrows, a name or an RGB triple, or one RGB row per arrow
lineWidth 1.0 the width of the shafts in points
antipodal False draw segments from P - D to P + D without heads, for axes
headSize 0.25 the length of the head as a fraction of the arrow
sides 12 the number of sides of the cone of a head

Output

items [lines3d, mesh3d], the shafts and the heads, or [lines3d] for antipodal arrows
