The PLAVelocity Tag together with the GlobalPSR Tag (also included) are tools to do velocity based interaction. A Softbody is a very good example. The points of a Softbody have different velocities when the body is deformed. The PLAVelocity Tag needs a PLA animation to be able to efficiently calculate the points current velocities. The velocity values will be written to a Vertex Map.

谷歌翻译：PLAVelocity标签一起GlobalPSR标记(还包括)工具基于交互的速度。一个软体是一个很好的例子。软体的点有不同的速度,当身体变形。解放军PLAVelocity标签需要动画能够有效地计算当前速度点。速度值将被写入到一个顶点映射。
