Object

对象

The position and direction of the gravity is controlled using the object’s axis system. Drag the name of the object that will represent the gravity’s position and direction from the Object Manager and drop it into this box.

重力的位置和方向是由物体的轴系控制的。从对象管理器中拖动表示重力位置和方向的对象的名称，并将其放入此框中。

Type

类型

Two types of force field are available: Planar (2D) and Spherical (3D

力场有两种类型: 平面(2D)和球面(3D)

Planar

平面

With Type set to Planar, the force will be applied perpendicularly to the object’s XY plane (i.e. along its Z axis). An arrowhead appears in the viewport to indicate the direction of the force. You can adjust the size of the arrowhead using the Icon Size setting on the Attribute Manager’s Node Properties tab.

类型设置为平面，力将垂直作用于物体的 XY 平面(即沿 z 轴)。在视图中出现一个箭头来指示力的方向。您可以使用属性管理器的节点属性选项卡上的“图标大小”设置来调整箭头的大小。

Spherical

球形的

If Type is set to Spherical, the force will be applied spherically towards the object’s origin. This mode is especially useful for gathering particles together. The Spherical gravity force is shown in the viewport as a sphere, the size of which you can adjust using the Icon Size setting on the Attribute Manager’s Node page.

如果类型设置为球形，力将作用于球形的对象的原点。这种模式对粒子聚集特别有用。球形重力在视图中显示为一个球体，你可以使用属性管理器的节点页面上的图标大小设置来调整球体的大小。

Strength[-∞..+∞]

强度[-∞ . . + ∞]

This is the strength of the gravity force. The higher this value, the stronger the force of gravity exerted on the particles. Not only will the particles change their direction of movement, they will also accelerate. You can enter negative values, in which case particles will be pushed away from the object’s origin.

这是重力的强度。这个值越高，作用在粒子上的重力越大。这些粒子不仅会改变运动方向，还会加速。您可以输入负值，在这种情况下，粒子将被推离物体的原点。

Decay[0..+∞]

衰变[0. . + ∞]

Controls the decay of the gravity force with increasing distance from the object’s origin. A value of 0 disables the decay, causing the gravity to affect all particles no matter how far away. Higher values scale the influence exponentially. The further away a particle is from the object’s origin, the weaker the force will be that is exerted on it. The higher the Decay value, the smaller the area around the object will be where the force will noticeably affect the particles.

控制重力随着距离物体原点距离的增加而衰减。数值为0时，衰变就失效了，导致重力影响所有的粒子，不管它们有多远。更高的数值会使影响呈指数级增长。粒子离物体原点越远，作用在它上面的力就越弱。衰变值越高，物体周围的区域就越小，这个区域受到的力会明显地影响粒子。

Mass Dependence[-100..100%]

大规模依赖[-100. . 100% ]

Gravitational dependency (in %) in correlation to a particle’s mass. The greater the mass the more it will be affected by Gravity.

与粒子质量相关的引力依赖性(%)。质量越大，它受重力的影响就越大。

Size Dependence[-100..100%]

尺寸依赖[-100. . 100% ]

Gravitational dependency (in %) in correlation to the size of the particles. The larger the particle, the more it will be affected.

引力相关性(%)与粒子的大小相关。粒子越大，受到的影响就越大。

Additional input ports:

其他输入端口:

• On

•安

A Boole value of True switches the node on; a value of False switches it off.

值为 True 的 Boole 将打开该节点; 值为 False 将关闭该节点。

• Animation Time

•动画时间

Since the node’s parameters can be keyframe animated, by default the Cinema 4D time is used internally to ensure the values are interpolated correctly. However, you can pass your own time value to this port. This should be of the data type Time, which is a Real number in the simplest case. If no value is passed, Cinema 4D’s time is used.

由于节点的参数可以是关键帧动画，默认情况下 Cinema 4D 时间在内部使用，以确保值被正确插值。但是，您可以将自己的时间值传递到此端口。这应该是数据类型 Time，在最简单的情况下，它是一个实数。如果没有值传递，使用 Cinema 4D 的时间。

• Particle

•粒子

Connect this port to the stream of particles that should be affected by the gravity force, such as to the Particle output port of a PPass node.

将这个端口连接到应该受到重力影响的粒子流，例如连接到 PPass 节点的粒子输出端口。
