Hello,

I wish to know to what accuracy extent PhysX can simulate real world scenarios. This is not for games but for more practical and professional application development. Take the following case for instance: a character pushes a chair or box by applying a force on it. I then track the acceleration of the box. How accurate can that acceleration be relative to what it should be really? With that regards how do other physics engines compare? I am aware of the visual effects drawback that occurs when more accuracy and precision is increased. My question is: to what extent can we increase the accuracy and precision? I do not really care about the visual drawback for this question.

Thanks.

I can not tell you how exactly accurate PhysX SDK will be in this particular case, but bear in mind that like any other game physics engine, PhysX trades precision for performance.

You might want to duplicate this questions at PhysX dev. forums, maybe someone will provide more details.

Thanks for directing me to the dev forums. I just posted my question there too.
