PRollingBasic 基础Parameter 参数
Parameter
参数
These settings define how particles should roll over a surface or how they should squash and stretch.
这些设置定义了粒子应该如何在表面上滚动，或者它们应该如何压缩和拉伸。
类型
The node offers two modes, which you set here:
这个节点提供了两种模式，你可以在这里设置:
滚动
Enable Roll so that particles will roll according to their size and velocity. The Axis values define the axis about which the rolling takes place.
启用滚动，以便粒子将根据他们的大小和速度滚动。轴值定义了滚动发生的轴线。
旅行方向
Enabling the Direction Of Travel mode means that particles will be scaled along their direction of travel, in which case Stretch controls the amount of stretching.
启用行进方向模式意味着粒子将沿着它们的行进方向缩放，在这种情况下，拉伸控制拉伸的量。
懒惰[0. . + ∞]
Controls how long, in seconds, it takes for the particles to fully adopt the new rolling setting. The higher this value, the slower the transition. This setting can help you to achieve a smooth, gradual change rather than an abrupt, unnatural one.
控制粒子完全采用新的滚动设置所需的时间，以秒为单位。这个值越高，转换越慢。这种设置可以帮助你实现平稳、渐进的变化，而不是突然、不自然的变化。
Axis [ XYZ ]
If Type is set to Roll, these Axis values define the axis about which the particles will be rotated.
如果 Type 设置为 Roll，则这些轴值定义粒子将围绕其旋转的轴。
The Stretch input of the PRolling node elongates
particles along their direction of travel. So, here we are using the speed of the particles to control by how
much they are stretched. PRolling 节点的拉伸输入使粒子沿其行进方向拉长。这里我们用粒子的速度，来控制它们被拉伸的程度
The Source value defines which axis will be used for the rolling. If the Invert option is enabled, the chosen axis is inverted to give the negative direction of the chosen axis. For example, if the option is enabled and Source is set to Z, the negative Z axis will be used.
Source 值定义将用于滚动的轴。如果启用了反转选项，则所选轴线将被反转，从而给出所选轴线的负方向。例如，如果启用了该选项并且 Source 设置为 z，则将使用负 z 轴。
伸展[-∞ . . + ∞% ]
This value is used as a factor for stretching the particles along their direction of travel. The effect depends on the speed of the particles. Using a value of 0.1 will stretch the particles 10 times their usual length, whereas a value of 0 leaves them unchanged.
这个值被用来作为一个因素拉伸粒子沿着他们的旅行方向。效果取决于粒子的速度。使用0.1的值将粒子拉伸到正常长度的10倍，而0的值将粒子保持不变。
Additional input ports:
其他输入端口:
•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。
•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。
•粒子
Connect this port to the stream of particles that you want to be rolled, such as to the Particle output port of a PPass node.
将这个端口连接到要滚动的粒子流，例如 PPass 节点的粒子输出端口。
