  Motion paths for particle collision

  Posted by Jonathan Baldwin on August 27, 2010 at 4:52 pm

  I am trying to create an effect to replicate proton collisions seen in particle accelerators:

  Basically, I am trying to have objects moving across the screen that keep a solid path behind them (tracks). The only ways I have found to create this effect are with “CC Force Motion Blur,” but it’s fading out the object instead of keeping it at a consistent, solid value.

  I am thinking there might be a way with Echo, but that hasn’t worked out for me…

  Some objects will be curving slightly, or branching off into other objects, so I need to create an effect that displays a solid path of motion, in the same way you would hold down “bulb” on a camera to expose a path of light…

  This might work. You make duplicates of the layer. The website also has some good inelastic equations for particles too.

  also, if you want cascading opacity with whole images, then read this post

  I recommend using paths on one or more shape layers and then using the Trim Paths operation to trim and extend the path as needed.
