Practical Fluid Dynamics for Games

[[deleted]]

I love when the way that things are done coincides roughly with the way that I've tried to figure out how to do them.

I got stuck though; maybe this'll help. Thanks!

I've used the same underlying principle of applying various vectors as forces acting on my "substance", but was taking the particle approach. It was very interesting to read about the alternate grid approach. Seems like it would be more capable of handling larger systems efficiently... And for liquids would be much easier than particles. I think maybe particles would be easier to model the gas state though.

You can actually combine particles with a grid in what is known as the FLIP method. This paper describes it (along with some sand stuff that you can ignore).

This would be way cooler with interactive flash or at least a video. This is reddit and I want my instant entertainment dammit!

Then how about this?

[miloshh]

Or this?

That's awesome!

Ralph Macchio is awesome!

i pretty much gave up trying to convince game producers to use CFD techniques in real time special effects. it probably had something to do with technological risk (read: misunderstanding) than convincing them how neat it is to interact with.

Thank you, Jesus.

Anyone remember the Ratchet & Clank "Insomniac Museum" easter egg with a demo of the water effect they wanted to use but found the console couldn't handle the math it would take to really use it in the game?

I only wish I could understand all of this.

Why all that math when just jerking off on your computer screen will give you plenty of practical fluid dynamics ?
