This node generates a bounding box around the positions of the particles in the connected Particle Root Node. This is typically used for nodes which work on a limited bounding region such as Field Nodes which need to track a particle simulation that has an unknown location and bounds, e.g. as the result of following tracking data.

As the bounds of a particle simulation often varies greatly from frame to frame as particles move or are spawned and die, the Smoothing Amount attribute may be used to control the smoothing of the size and location of the generated bounding box over multiple frames.

There is a latency of several frames in the bounding box generation in order to pipeline the processing and not impact on performance.
