Project physics trajectory

I’m trying to basically recreate the effect from Angry Birds where you pull back on the bird and it creates a little line of dots showing the projected trajectory of the bird. I’m using the default Unity physics.

I’ve seen this question or similar questions asked a few times but with no real answers outside of “roll your own physics”. Is there a way to do this easily without reinventing the wheel?

You could have a look at this script from the Unify Wiki:

You could use this script by feeding it incremental distances from your origin to your target, and find the collision point at each distance, and put a dot there or whatever you like.
