We are developing a new fluid solver using machine learning, capable of simulation large simulations (for foam-less fluid ~10 million, with foam a bit less) with surface generation, rigid body coupling, multi-phase and rendering in real-time. The quality-running time trade-off is controllable.

It looks really awesome, could you show how it looks like with a quite low res so that the performance impact is only something like 3 ms? Does it scale linearly with the particle amount, so will 100 times less particles run 100 times faster? In games you often don’t need super high accuracy.

Based on my knowledge, a typical games give only several milliseconds per frame to a physics engine, and mostly only on CPU. We haven’t optimized our method much (it’s simply a basic vanilla implementation), so there is a large space for improvement (my guess is that 5x should be achievable). Also several approximations (height map and low precision/skip calculations outside of the region of interest) are possible, however 3ms on CPU with current hardware seems out of reach.

Why do you mention the CPU here? Isn’t the fluid sim only heavy on the GPU?

Also, you mention CUDA, if you want this to be usable in games you should make it use OpenCL, direct compute or vulkan compute so that it runs on AMD and Intel GPUs too, for now direct compute is probably the best.
