After lacking a useful idea for almost the whole compo time I got one on the very last day. 8 hours of hard work later this is the result. It's not as polished as I would have liked it but the deadline is here so there is no time for that.
The entry shows a window that gets shattered over and over again. The window is rendered using a vononoi (worly noise) shader.
The window in itself is dynamically created in two ways.
If the window is going to be exploded its generated by a bunch of random points.
If its the 'rail gun' destruction effect the points are created as circles around the impact point in the window.
The point cloud is then triangulated and from those triangles shards are created that are in turn simulated using a verlet integrator.
I hope you like it and that it works on your machine.
Update: Realized I had an hour left. Did some color tweaks and fixed so he cycles between the two destruction modes.
