ThreeDimSim: Break thru

This example shows a simulation of a car driving into a brick wall. The car is a compound mesh with more than 3800 facets, that's driving into a wall of 400 bricks. What happens at a speed of 18 km/h is shown below:

At a higher speed (100 km/h) the effect is totally different:

The script cars.thd is straightforward: It loads the mesh defining the car, and creates all brick-objects. Then  the initial speed of the car is set, and the simulation is started. The replay feature is used to take different snapshots and video clips from the same simulation.
