力场物体

Expanding the Fields functionality to dynamically moved elements would produce interesting results. This is exactly what the Field Force object does. It affects, for example:

将 Fields 功能扩展到动态移动的元素会产生有趣的结果。这正是力场物体所做的。例如，它会影响:

• the velocity of particles ( 粒子的速度(Standard Particles 标准粒子 und 和Thinking Particles TP粒子 (using the (使用P Force object P 力物体)).
• objects controlled by 控制的对象Dynamics 动力学
• other elements to which a Force tab is assigned (e.g., Soft Body tag, Jiggle deformer, Hair object, Spline Dynamics tag, etc.). 其他分配力标签的元素(例如，软体标签，微动变形器，毛发对象，样条动力标签等)

A Field Force is nothing other than a spatial distribution of vectors that define the direction of the force. A simple force that you should be familiar with is, for example the Gravity object from the particle system. This works in exactly one direction by default: down. This doesn’t exactly make it very flexible to use.

力场就是定义力的方向的向量的空间分布。一个简单的力，你应该熟悉的是，例如重力对象从粒子系统。默认情况下，这只在一个方向起作用: 向下。这并不能使它变得非常灵活。

The Field Force described here can be controlled freely using Fields. Fields ascertain spatially differing values that control the strength of effects (e.g., movement). For the Field Force, these Fields will be analyzed in order to calculate direction vectors.

这里描述的战场力量可以通过使用磁场来自由控制。字段确定控制效果强度(例如，移动)的不同空间值。对于场力，将分析这些场，以便计算方向矢量。

The following directions will, for example, result if the respective object is dragged into the Field list:

例如，如果将相应的对象拖动到 Field 列表中，将产生以下方向:

• with a Spherical Field, for example, from small to large values, i.e., radially in the direction of the center point. 例如，一个球形场，从小到大，例如，径向中心点的方向
• with a Linear Field, the direction will be axial (X axis) 在线性场中，方向是轴向的(x 轴)
• with a Random Field, more or less random directions. If this is a Noise Random Field: always from smaller to larger regions. 随机场，或多或少的随机方向。如果这是一个噪声随机场: 总是从小区域到大区域
• with a Spline Field, the direction of the force can run along the spline (especially suited for controlling particle streams) or perpendicular to the tangent. 使用样条场，力的方向可以沿着样条运行(特别适合于控制粒子流)或垂直于切线
• with particles, the velocity vectors of the next particles define the direction. 对于粒子，下一个粒子的速度矢量决定了方向
• with volume generators, a direction will be calculated for each Voxel (for polygon objects initially in the direction of the surface Normals or away from them), which will be applied to the entire Voxel. 使用体积生成器，将计算出每个体素的方向(对于最初在表面法线方向或远离它们的多边形对象) ，这将应用于整个体素

Certain elements define spatial vector distribution: Volume objects can, for example, be assigned a velocity directly. The Volume Builder (Volume TypeVector) can also generate directional vectors. These objects can then also be used in the Field Force.

某些元素定义空间向量分布: 例如，可以直接为体对象指定速度。体积生成器(体积类型矢量)也可以生成方向矢量。这些物体也可以在力场中使用。

Since the possible combinations in Cinema 4D are almost endless, the description offered here can only be seen as the tip of the iceberg. Experiment thoroughly with all Fields - you’ll be surprised at the number of spectacular effects that can be created.

由于C4D可能的组合几乎是无穷无尽的，这里提供的描述只能被看作是冰山一角。在所有领域进行彻底的实验——你会惊讶于能够创造的壮观效果的数量。

Not all Fields (e.g., Shader Field) or modifier layers (those that only affect colors such as the Colorizer and the Color Filter) work with Field Force. Some settings have no effect in certain circumstances (e.g., the Remapping menu’s settings if Direction is set to No Remap).

并非所有字段(如 Shader Field)或力场层(那些只影响颜色，如着色器和颜色过滤器)都能使用字段力。有些设置在某些情况下没有效果(例如，如果方向设置为无重新映射，则重新映射菜单的设置)。

To make it obvious that an element placed into a Field works, a vector view will be displayed in the Viewport (this can be adjusted using the View menu’s settings). If this vector view is not displayed, the element does not work with the Field.

为了使放置到 Field 中的元素能够正常工作，一个矢量视图将显示在 Viewport 中(这可以通过 View 菜单的设置来调整)。如果未显示此向量视图，则该元素不能与 Field 一起使用。
