### Vectors (visual element)

This visual element visualizes the values of a vectorial particle property as arrows. The Displacement vectors modifier, for example, outputs the calculated displacement vector of each particle as a new particle property named `Displacement`. This property is linked to a corresponding Vectors visual element, which appears under the "Visual elements" section of the pipeline editor (see screenshot), and which generates and controls the visualization as arrows.

#### Arrow coloring

Note that, by default, all arrows are rendered in the same uniform color. If desired, however, you can give each arrow an individual color by setting the `Vector Color` particle property, for example using the Color Coding or Compute Property modifiers.

#### Parameters

Shading mode

  Switches between a three-dimensional (normal shading) and a two-dimensional representation (flat shading) of arrows.

Scaling factor

  Arrows are scaled by this factor for visualization purposes. The default value is 1.

Arrow width

  The diameter of arrow lines.

Alignment

  Controls how arrows are positioned relative to the particles they are associated with.

Reverse direction

  Flips the direction of each arrow, swapping its head and tail.

Arrow color

  The display color of arrows. This uniform color is used when the `Vector Color` particle property is not present. Otherwise the per-particle colors defined by the `Vector Color` property are used to render the arrows.

Transparency

  The degree of semi-transparency of the arrows.

Offset

  Offset vector by which all arrows should be displaced. The offset parameter can be used to move the arrows fully in front of or behind the particles.
