PhsyX Fluid Simulation Continues To Impress With New Videos
We're starting to get a closer idea of what we can and cannot expect from in-game fluid simulation during this next generation of gaming. A small team testing various densities of particle-based water effects showcased some degrees of high-end water simulation and lower-end water simulation.
The video above is a continuation of the previous video released showcasing the power of Nvidia's PhysX in a closed environment simulation. The thing worth taking away from this is that the Lighthouse simulation, running at a paltry 15 frames per second on a GTX 680, showcases that when the smaller scale fluid simulations are doubled up and just over a quarter of a million fluid particles are in effect along with 2 million diffuse particles, we're looking at the real technical ceiling for this kind of software technology (for today's generation of mid-range GPUs, anyway).
It would require a hefty amount of optimization for this to work within a real-time game environment that's also rendering all the other big-time effects many gamers are used to seeing and experiencing. While on the lower scale at just half the parity and particles of the Lighthouse demo, we're looking at 30 consistent frames per second on the GTX 680 and the GTX 580. That's not too bad so long as the diffusive particle barrier isn't stretching beyond the 1.5 million mark.
The team gives a pretty spiffy breakdown of how they achieve the effects that they do in the tech demos with the third (and presumably final?) part of the demo series, which showcases how they're optimizing the tech to lower the "gelatine effect” that many fluid simulation systems suffer from. It's pretty cool stuff.
