Parameter

参数

• Position[XYZ ]

•定位[ XYZ ]

Sets the global position of the particles.

设置粒子的全局位置。

• Velocity[XYZ ]

•速度[ XYZ ]

Defines the direction and speed of the particles. The length of the vector sets the speed and the direction sets the direction of the motion.

定义粒子的方向和速度。矢量的长度决定了速度，方向决定了运动的方向。

• Life

•生活

Sets the new life span of the particles, in seconds.

设置粒子的新寿命，以秒为单位。

• Age

•年龄

Sets the age of the particles.

设置粒子的年龄。

• Size[-∞..+∞]

•大小[-∞ . . + ∞]

The Size value is a scaling factor for the objects used as particles. The ratio of Size to Bounding Radius (see the PShape node for details on the Bounding Radius) gives the scaling factor: (Size/Bounding Radius)*size of the object=size of the particle object. So if you want the particle object to be exactly the same size as the original object, set Size to the same value as Bounding Radius. You can vary the size of each particle using the Size Variation parameter.

Size 值是用作粒子的对象的缩放因子。尺寸与边界半径的比率(参见边界半径 PShape 节点)给出了尺度因子: (尺寸/边界半径) * 物体的尺寸 = 粒子物体的尺寸。因此，如果你想粒子对象完全相同的大小作为原始对象，设置大小相同的值作为边界半径。您可以使用 Size Variation 参数改变每个粒子的大小。

• Scale[XYZ ]

•规模[ XYZ ]

The axis of each particle is scaled by this value, enabling you to squash or stretch particles.

每个粒子的轴都按此值缩放，使您能够压缩或拉伸粒子。

• Mass[-∞..+∞]

•质量[-∞ . . + ∞]

Defines the mass of the particles as a Real number (i.e. the value must be of the data type Real). The mass will affect how the particles react to dynamics forces such as wind. The greater the mass, the less the particles react to these forces.

将粒子的质量定义为一个实数(即值必须是数据类型 Real)。质量将影响粒子如何反应动力，如风。质量越大，粒子对这些力的反应就越小。

• Alignment

•调整

This matrix sets the orientation of each particle, not the direction in which they move.

这个矩阵设置每个粒子的方向，而不是它们移动的方向。

• Spin

•旋转

You can connect a PSpinConvert node to this port to control the rotation of the particles.

您可以将 PSpinConvert 节点连接到这个端口来控制粒子的旋转。

• Shape

•形状

Here you can change which object is used as the shape the particles. Note that you cannot connect a PShape node directly to this port. Instead use, for example, a PGetData node to read a shape and pass this on to the PSetData node.

在这里你可以改变哪个物体被用作粒子的形状。请注意，不能将 PShape 节点直接连接到此端口。而是使用，例如，一个 PGetData 节点来读取一个形状并将其传递给 PSetData 节点。

• DT Factor[-∞..+∞]

• DT 因子[-∞ . . + ∞]

DT stands for Delta Time. This is a multiplier for the internal calculation of the particles’ time values. The default value is 1, which means that particle time is equivalent to animation time. Lower values will lead to a slower particle time, higher values to a faster particle time. You can use this for fast forward or slow motion particle effects.

DT 代表德尔塔时间。这是粒子时间值内部计算的乘数。默认值是1，这意味着粒子时间等同于动画时间。较低的值会导致粒子时间较慢，较高的值会导致较快的粒子时间。你可以使用这个快进或慢动作粒子效果。

Color

颜色

• Random Seed[-2147483648..2147483647]

•随机种子[-2147483648. . 2147483647]

The randomness of any variation is based on this value. The same random look will be generated each time you play back the animation unless you change this value.

任何变化的随机性都基于这个值。除非更改此值，否则每次播放动画时都会生成相同的随机外观。

• 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。

• Particle

•粒子

Connect this port to the particle stream, such as to the Particle output port of a PPass node, whose values should be set.

将此端口连接到粒子流，例如连接到 PPass 节点的粒子输出端口，该端口的值应该设置为。

• Group

•小组

Here you can connect a TP Group data type, which you can access from a PGetData node, for example. This will allow you to assign the particles coming into the node to a new group (the group defined by the Group input port). You cannot connect a PPass node directly to this port.

在这里，您可以连接可以从 PGetData 节点访问的 TP Group 数据类型。这将允许您将进入节点的粒子分配给一个新的组(由 Group 输入端口定义的组)。您不能将 PPass 节点直接连接到此端口。
