A game like AirXonix

Hello everyone,

Right now I’m trying to start working on a game that is like AirXonix (see the video below).

In this game you are a sort of helicopter which has to raise the ground to a certain percentage.

Now I know how to do most of the aspects of the game, only one thing I’m wondering about.

This ONE THING is the raising of the ground. I was thinking of making hundreds of little boxes, but that might be to demanding for the performance…

Anybody might know how to achieve this?
