Affine body dynamics (ABD) efficiently simulate highly stiff objects. By replacing the rigidity constraint with a big stiffness penalty, ABD avoids expensive rigid CCD and brings orders of magnitude performance gains, i.e., two- to three-order on the CPU and an order more utilizing the GPU over prior IPC-based methods.

Amazing, your papers make me drop out of chair each time in amazement!

This is really cool work 😯

Wow very interesting research

@kiaranritchie3021 2 года назад

Great work! There are many applications where these stability and non intersection guarantees would be very welcome. Any chance we will see a public github with code?

Wonder what the downsides are. This algorithm isn't a use case for games or realtime simulations?

@minchenli2292 2 года назад

Our research is just published this month. It could sooner be applied to products. But for games, as the current engines already provide nice visuals, intersections may not be that crucial? Not sure what game developers and players think about it.

@@minchenli2292 VR applications probably would make more use of this kind of algorithm where precise collisions are preferred. Also crunching simulation time down in a offline renderer is always a good thing.

@@minchenli2292 modern game engines are completely unable to cope with physics and the needs of game developers.

@@minchenli2292 I want to make very interactive game someday, my opinion graphics are important, but actual interaction/physics is better.

@@minchenli2292 It will be very important for robotics simulation, such as in isaac sim. a lot of tasks in robotics require robot able to practice virtually at very fast speed and with very accurate tiny realistic contacts, not approximations for 'visual' effect. Congrats!
