Length

长度

You can select from the following options:

你可以从以下选项中选择:

• No Remap 无需重新映射: The length of the vectors will not change. However, certain Fields can produce unwanted results, e.g., extremely long vectors, that in turn produce unwanted results when the Normals are processed (you should then use a different option such as : 矢量的长度不会改变。然而，某些字段可能会产生不必要的结果，例如，极长的向量，反过来产生不必要的结果时，法线处理(然后你应该使用一个不同的选项，如Use Value 使用价值). These can be used for custom XPresso setups. )。这些可以用于自定义 XPresso 设置

• Normalize 正常化: The vector length will be set to 1. : 矢量长度将设置为1

• Use Value 使用价值: The Value channel provided by the Field will be used for the length. A Linear Field, for example, will then determine the vector length between left 0 and right 1. : 字段提供的值通道将用于长度。例如，一个 Linear Field 将确定从左0到右1之间的向量长度

• Inverse Square 逆平方: This is a special case, which can be used in conjunction with Dynamics. The vectors for a Spherical Field will behave similarly to the brightness falloff of a physical light source. Very strong at maximum (sphere center) and inverse square abatement with increasing distance from the center. This corresponds, for example, to the physically correct behavior of a gravitation source. 这是一个特例，可以与 Dynamics 一起使用。球面场的矢量表现与物理光源的亮度衰减相似。在最大值(球心)和反平方减少非常强，随着距离中心的增加。这对应于，例如，一个引力源的物理正确行为

Scale[-∞..+∞%]

刻度[-∞ . . + ∞% ]

This setting is a multiplier that affects the length of all vectors. For example, if a vector has a length of 4, this will be set to 2 if the Scale value is set to 50%.

这个设置是一个影响所有向量长度的乘数。例如，如果一个向量的长度为4，那么如果 Scale 值设置为50% ，那么这个值就会设置为2。

Invert Direction

倒转方向

Contrary to the remaining settings, this option affects the vector orientation and rotates it 180° in the opposite direction.

与其他设置相反，这个选项影响矢量方向，并向相反的方向旋转180 ° 。
