PSurfacePositionBasic 基础Node 节点Parameter 参数
Parameter
参数
Choose the object and whether the particles should be emitted from the object’s points, edges or polygons.
选择物体，粒子是否应该从物体的点、边或多边形发射。
对象
Drag the name of the desired polygon object from the Object Manager and drop it into this box.
从对象管理器中拖动所需的多边形对象的名称并将其放入此框中。
输入/选举
Use Type to choose whether the positions should be generated on the object’s points, edges or polygons (Type set to Face, Edges or Vertex respectively). In addition, you can restrict the positions to a frozen selection (i.e. a Point, Edge or Polygon Selection tag). Enter the name of the desired Selection tag into the Selection box. For details on frozen selections, please look up the Set Selection.
使用 Type 来选择是否应该在对象的点、边或多边形上生成位置(类型分别设置为面、边或顶点)。此外，您可以将位置限制为冻结的选择(即点、边或多边形选择标记)。在“选择”框中输入所需的“选择”标记的名称。有关冻结选择的详细信息，请查看 Set Selection。
Here we’ve stuck small, sphere-shaped particles to
the surface of a larger sphere. Remember to use a Particle Geometry object to hold the smaller particle
spheres and to set the Bounding Radius of the PShape node to a sensible value in relation to the size of the
particle spheres. 这里我们把小的球形粒子粘在一个大球体的表面上。记住使用粒子几何对象来保持较小的粒子球，并将 PShape 节点的边界半径设置为与粒子球大小相关的可感知值
Additional input ports:
其他输入端口:
•粒子
Connect this port to the stream of particles that should be emitted from or placed on the object, such as to the Particle output port of a PPass node.
将这个端口连接到应该从对象发射或放置在对象上的粒子流，例如 PPass 节点的粒子输出端口。
•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。
Output ports:
输出端口:
位置[ XYZ ]•
Outputs the random positions on the object. You can assign these values to particles by connecting this port to the Position port of a PSetData node.
输出对象上的随机位置。通过将此端口连接到 PSetData 节点的 Position 端口，可以将这些值分配给粒子。
正常•
Outputs the Normals of the random positions on the object. Using this information, you can set the velocity of each particle in such a way that the particles move perpendicular to the surface.
输出对象上随机位置的法线值。利用这些信息，你可以设置每个粒子的速度，使得粒子垂直于表面运动。
调整•
Outputs, as vectors, the current alignment of the particles.
输出，作为矢量，粒子的当前排列。
