Rectilinear Particle Motion Help

Recommended Posts

Hi Al, Dows anyone have any ideas on how to create rectilinear particle motion ie. random turns at 45 or 90 degrees for a few frames while moving towards a goal?  The closest example I can think of would be the fireworks in TRON:Legacy  See- http://vimeo.com/22507731 particularly the motion when they begin to fall that rectagular pattern.  Thanks for any help in advance.

You could try to rotate the velocity attribute of your particle as you desire. 

Here's an example using a POPvop to do just that. 

 

Like most things in Houdini, there are probably multiple ways to achieve similar effects.
