Forces

力量

This tab can be used to define many types of forces that should affect guides and hair, ranging from the common force of gravity to forces that can be applied to guides / hair by objects themselves. Furthermore, the effect of Cinema 4D particle modifiers can be included or excluded in the Forces field.

这个标签可以用来定义许多类型的力，应该影响导游和毛发，从共同的重力，可以适用于导游/毛发的物体本身的力量。此外，Cinema 4D 粒子调节器的效果可以包括或排除在力场中。

Hair to Hair

从毛发到毛发

Activating this setting creates a tube-shaped force field around each guide that will repel (positive Strength values) or attract (negative Strength values).

激活这个设置会在每个指南周围创建一个管状的力场，这个力场会排斥(正强度值)或吸引(负强度值)。

What can Hair to Hair be used for?

毛发到毛发可以用来做什么？

If we take a look at the brush from earlier in this manual, you will see that the bristles all stand perpendicular to the surface, giving the brush an unrealistic look. In order to slightly push the hairs of each bristle apart, activate the Rigid setting in the Dynamics tab and the Hair to Hair setting in the Forces tab. When this is done, the effects of dynamics will appear as below:

如果我们看看本手册前面的刷子，你会发现刷毛都垂直于表面，给刷子一个不真实的外观。为了稍微推动毛发的每个刚毛分开，激活刚性设置在动态选项卡和毛发到毛发的设置在力量选项卡。当这样做的时候，动态的影响将显示如下:

The brush at the bottom looks much more realistic.

底部的画笔看起来更真实。

Surface to Hair

表面到毛发

An active Surface to Hair setting allows polygonal objects to apply forces to hair. The object applying the force must have a Hair Collisions tag assigned to it. The force applied by the object is defined in the Hair Collisions tag.

一个活跃的曲面到毛发的设置允许多边形物体施加力到毛发上。施加力的物体必须有一个毛发碰撞的标签。物体施加的力是在毛发碰撞标签中定义的。

Gravity[-∞..+∞]

重力[-∞ . . + ∞]

This is basically the common force we are all familiar with from our lives on planet earth. By default, this setting has a negative value (-Y in the world coordinate system) - after all, gravity does not cause you to fall up …

这基本上是我们在地球上生活中所熟悉的共同力量。默认情况下，这个设置有一个负值(- y 在世界坐标系)-毕竟，重力不会导致你上升..。

Hair to Hair

从毛发到毛发

Radius[0..+∞m]

半径[0. . + ∞ m ]

This radius represents an imaginary tube around each guide, containing a force effect with an adjustable falloff that affects other guides.

这个半径代表一个假想的管周围的每个指南，包括一个力的影响与可调整的跌幅，影响其他指南。

Strength[-∞..+∞]

强度[-∞ . . + ∞]

Use this setting to define the force strength, which is emitted in a radial manner around the guide. The strength will abate, as defined in the Falloff setting and will have no effect outside the defined Radius. Positive values will repel, negative values will attract.

使用此设置来定义围绕导轨以径向方式发射的力量强度。强度将减弱，作为定义在弗洛夫设置和将没有影响以外的定义半径。积极的价值观会排斥，消极的价值观会吸引。

Max Strength[-∞..+∞]

最大强度[-∞ . . + ∞]

This setting ensures the hair does not explode, by limiting the amount of strength applied. A square falloff would, for example, tax dynamics beyond its limits since the falloff would be infinite at a radius of 0. The Max Strength setting makes sure the forces applied remain within reasonable limits.

这个设置通过限制使用的力量，确保毛发不会爆炸。例如，一个正方形的衰减将超出其极限，因为衰减在半径为0时将是无限的。最大强度的设置，确保应用的力量保持在合理的限度内。

Falloff
Custom

Use this function graphs to define the falloff between the guide and the effect radius defined in the Radius setting. Use the Custom option to define a custom falloff.

使用这个函数图可以定义导轨和半径设置中定义的效果半径之间的距离。使用 Custom 选项定义自定义衰减。

Force Objects

强制物体

Mode
Forces

模式力量

If other forces should affect the hair (e.g., Cinema 4D particle modifiers), they can be included or excluded using these options.

如果其他力量影响毛发(例如 Cinema 4D 粒子力场) ，可以使用这些选项包括或排除它们。

Simply place the corresponding object into the Forces field and select either the Include or Exclude option.

只需将相应的对象放入 Forces 字段并选择 Include 或 Exclude 选项即可。
