Parameter

参数

On this page, you can set the size of particles and, optionally, how the size changes over the life span of the particles.

在这个页面上，您可以设置粒子的大小，以及随着粒子寿命的变化，大小是可选的。

Size[-∞..+∞]
Variation[0..100%]

尺寸[-∞ . . + ∞]变化[0. . 100% ]

The Size parameter is a multiplier for the size of the particles. For example, a setting of 5 means the particles will become five times larger. You can vary the size of the particles using the Variation parameter.

Size 参数是粒子大小的乘数。例如，设置为5意味着粒子将变大5倍。您可以使用 Variation 参数改变粒子的大小。

Over Age
Age Gradient

超过年龄/年龄梯度

If Over Age is enabled, you can use the gradient to control the size of particles based on their ages. For example, you can make particles grow larger as they get older. The Age Gradient is especially useful for explosion effects and smoke — smoke or steam spreads and thins out over time.

如果超龄启用，你可以使用梯度来控制粒子的大小基于他们的年龄。例如，你可以让粒子随着年龄的增长而变大。年龄梯度对于爆炸效果和烟雾或蒸汽随着时间的推移扩散和稀释特别有用。

The left edge of the gradient represents the moment the particles are born and the right edge the moment they die. Thus, the gradient covers the life span of the particles. The brightness at a position on the graph acts as a multiplier for the Size value.

梯度的左边缘表示粒子出生的时刻，右边缘表示粒子死亡的时刻。因此，梯度覆盖了粒子的寿命。图形上某个位置的亮度充当 Size 值的乘数。

To create a knot, click in an empty area below the gradient and a knot of the color at that position will be added. To change the color of a knot, double-click it and choose the desired color using the system color dialog. To remove a knot, Drag & drop it away from the gradient. The small diamonds on the gradient are bias handles and they pull the interpolation of the color knots from side to side for more control over how the gradient changes. How such gradients work and the effect individual interpolation methods have is explained here.

要创建一个结，点击在一个空白区域下面的梯度和一个结的颜色在该位置将添加。若要更改结的颜色，请双击它并使用系统颜色对话框选择所需的颜色。要删除一个结，拖放它远离梯度。梯度上的小金刚石是偏置手柄，他们拉从一边到另一边的颜色节点插值，以便更好地控制梯度的变化。这种梯度如何工作和影响个别插值方法已在这里解释。

This example shows how you can affect the size of a particle so its size will vary depending on its speed (the length of the velocity vector). The Math mode is included to produce a single value from the velocity vector and scale the speed down to a sensible value. 这个例子展示了如何影响粒子的大小，使其大小根据其速度(速度向量的长度)而变化。Math 模式可以从速度向量中产生一个单一的值，并将速度缩放到一个合理的值

Additional input ports:

其他输入端口:

• Particle

•粒子

Connect this port to the particle stream that should be re-sized, such as to the Particle output port of a PPass node.

将此端口连接到应该重新调整大小的粒子流，例如连接到 PPass 节点的粒子输出端口。

• 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 that 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。
