Curiosity of New PhysX Physics Accuracy

[zoctipus]

I am curious of PhysX Physics Accuracy, I have done some research but couldn't find many answer. Many comment online (especially earlier) says that PhysX is a game engine is optimized for speed not suitable for high fidelity physics simulation. In the same time, I am also hearing that Nvidia's enphasis in moving into robotic field and increased physical accuracy and updating PhysX5’s physic calculation datatype precision and solver. I wonder what would you say about it? What is improvement is PhysX's rigidbody physix compare to previous version? Will it still just be a game engine or can it be used for higher fidelity industry or even scientific research

Hi @zoctipus - it is difficult to make general accuracy statements or assurances about an all-purpose simulator as there are many variables in the simulation scene setup and settings that may affect accuracy. We do have users that achieve high-enough accuracy for robotics and industrial simulations, but what can be achieved depends on the specific simulation and what level of fidelity is required.

Do you have any news on double coordinates being supported in PhysX?

Hi @Zeblote ! No news, we have no plans to support double precision at the moment.
