3.5 Follow The Leader 2.0【跟随领导者2.0】

The grid is defined at the System level so all emitters can reference it.

【在系统层级定义网格，因此所有发射器都能引用它】

This emitter swirls a ring of particles around the Z axis.

【此发射器生成几个圆环排列的围绕Z轴转动的粒子】

The Neighbor Grid is filled inside this scratch module.

【在此模组填充相邻网格】

The Attribute Reader is used in conjunction with the Neighbor Grid to resolve particle indices into useful data.

【结合相邻网格使用属性读取器来把粒子索引处理为有用的数据】

The Neighbor Grid is queried from the Query Neighbor Velocity scratch module. It queries the current cell plus the adjacent cells so data can overlap and interpolate smoothly as particles cross from one cell to another.

【在查询邻居速度本地模组里查询相邻网格。它查询当前单元格和相邻单元格，所以数据能重叠，且当粒子从一个单元格移动到另一个单元格时能平滑地过渡】
