Comparing Bullet, Havok, Newton, ODE and Physx and question

Post by intresto »

I found a very good, recent (2012) paper comparing Bullet, Havok, Newton, ODE and Physx:

An Evaluation of Open Source Physics Engines for Use in Virtual Reality Assembly Simulations
Hummel et al
Here http://elib.dlr.de/79462/1/74320346.pdf


I also have a question:

If a collection of rigid bodies stacked on top of each other (e.g. boxes in a shipping container or rocks in a dry stone wall) have settled into a stable and static arrangement under the influence of gravity and friction are there physics engines which can resolve, and display as vectors, forces at points or surfaces of contact?

Thanks

All engines allow you to iterate the current contact points. Then you can visualize this is in any way that is needed for your use-case.

Thanks Dirk
Good to know it's possible. I'll continue this question in "Support and Feedback".
