Test render of a 3D map generated straight from OSM data using the tool OSM2World. Shown is a large part of Berlin, mainly Lichtenberg and Treptow in background. Building textures are not accurate because they are randomly applied.

![Arecibo Observatory Collapse Simulation [8K]](https://i.ytimg.com/vi/AqBvyx_zSK4/mqdefault.jpg "Arecibo Observatory Collapse Simulation [8K]
This is a structural simulation of the collapse of the Arecibo Observatory in 2020. The simulation implements the three major failure events which ultimately led to the progressive failure causing the platform to fall into the dish.
The simulation is based in part on actual physical data such as mass and strength for the larger components, and in part on plausible estimations. What appears to be multiple simulations at different points in time is actually one large global simulation. Deviations from reality are to be expected due to the fact that the simulation software runs completely autonomous, only the main initial failure points have been triggered by a predefined script. Nothing is animated by hand.
01:06 Cable M4N (Auxiliary cable from Tower 4) socket failure
01:40 Cable M4-4 failure
02:22 Cable M4-2 failure
Failure history:
2020-08-10 Tower 4 auxiliary main cable north comes loose from the socket (#301)
2020-11-06 Tower 4 main quadruple cable south broke, one of four (#101)
2020-12-01 Tower 4 main cable total failure and collapse
Some stats for nerds:
Base 3D model - 1.87 million polygons
Simulation model - 12,900 elements + 136k constraints
Simulation time - ~16 h
