Hello,
I am building audioreactive visuals for a small diy festival and since it is water themed I want to try out the fluid simulation of fuse to build a sewage cavern, where the water pours out of a tube into a basin.
I started by modifying the hero image help patch, because it already has lots of the parts I want. I want the fluid sim to act on a particle system so that I can texture and light the particles. The velocity of the particles propelling to the side is also already what I want.
What I am trying to figure out is how to make the particles have mass, so that they pour into the basin that I created with sdf obstacles.
For the last two days I have been playing around with different parameters trying to figure out how the fluid simulation works and compared a lot of different help patches trying to make sense of it all, but I am in a bit of a dead end, probably beacuse I am a beginner in Gpu coding. So if anyone has some tips or knows how to make my idea happen that would be great.
Here are some pictures from my patch:
I experimented a lot with the Attributes, Fluid entities and sdf operators but never really understood how it worked and only the velocity and temperature gave real results the rest of the attributes I could get to show any results.
Then I discovered that the fluid simulation gets fed into the particle system though the texture3dforcefield and tried to add other forcefields for other attributes of the fluid sim, but that also often just blew up the simulation or didn’t work at all.
I also tried to control the gravity of the particles through the force pin in the integration stage and that did force the particles to the ground but didn’t work the way I wanted it to do, since it doesn’t influence the fluid simulation, only the particles.
Lastly, I might have a little extra challenge since my PC isn’t the strongest and my GPU is a NVIDIA GeForce GTX 1070 (8 GB) Zotac that isn’t really supportet anymore and some of the help patches dont work. For example when I open the fluid introduction the simulation works for a few seconds but then it “explodes” and disappears. I will go to my university later where there are better PCs and try out some stuff there.
I might be in over my head but I really think it would look super cool to have an audioreactive fluid sim to dance to :)
