box2d. platformer. destructible terrain

Question

So, I want to create a platformer with destructible terrain. I use a physics engine box2d for java. I have an idea to do a lot of small static balls that will be destroyed at some impact on them. Are there better ideas? Not much this will slow down performance?

And the second question. If I do so, how can fill this area picture? Something similar to the style of worms.

Answer 1

Beside the fact that your idea should also work it might have a lack of resolution which makes me prefer this method.
