How accurate is Bullet for this type of collisions?

Recommended Posts

I am wondering how well will Bullet work for structures e.g. buildings, bridges, various other made up objects? Say you have a wrecking ball, tidal-wave, or earthquake to try and simulate some force to act on the structure to bring it down?

And what would need to look at specifically in Bullet before I start diving into Bullet?

Thanks!

Bullet is just for games and movie physics effects, not for realistic engineering. It has been used in the destruction movie 2012, which required a lot of work on authoring and pre-fractured data, convex decomposition etc.. So it mostly depends on your toolchain.

The collision detection can be very accurate, but the collision response is approximate, due to iterative constraint solver. You can increase the quality by using a smaller time step, more solver iterations etc.
