Testing the new SoC FluidSimulator - Screenshots & movie

JoOngle

Get ready for some real fun!

I've been testing the Summer Of Code Fluid simulator in Blender
because there's a build available in the developers forums for Linux right now!

Here's my little test movie:

(2 mb download - mjpeg avi)

Man...playing with Fluids are so much fun I'm probably going to get the whole
weekend with this stuff.

Right now there are only a few options to play with, and the whole action is limited
to the bounding-box (no shapes will affect it!) and all objects to be fluid MUST be
inside the "box" itself. No object intersection yet either..

But still.... Using the imagination...there's no end to the possibilities really...

Just out of curiosity, how long did that animation take to calculate on your machine?

JoOngle

Sorry to leave that information out....my bad...here are the details:

Renderer: Yafray
No.Frames: 140
Time: 5 minutes
Processor: Athlon XP 2500+
Ram: 2 Gigabytes
OS: Linux

FluidEngine: SoC BF-Blender 2.38 (Gabio's build)
Precalc time: 4 minutes
Objects: 2 (1 Domain, 1 Fluid)
Object 1: 10 faces
Object 2: 1660 faces

Gabio

yea well, I suppose without at least 1go of ram you'll not get good quality sim out of it. It's a heavy job, fluid sim...

JoOngle

Here's a bigger one:

http://www.hamsterking.com/blender/3d/softice2.avi (Warning - 6 mb file!)

A milkbottle with a drop of soft-ice beeing dumped into it. :P

Anyway, it took only less than 6 minutes to bake it...and consists of 250 frames
that's not bad at all. I'm quite impressed by the speed of the simulator...
It even has 2 intersecting fluid objects (the milk and the softice)

...let's see if we will be equally impressed when collision detection with intersecting
objects come into play....when that part has been developed.

Looks good JoOngle. Can you make a better one though? You have a 2500+ processor with 2 GB Ram, let's see what this fluid sim can do 8).

If you don't have time, don't bother. What you could do to speed it up is to use some sort of black liquid or deep blue like the ocean so that you don't need raytracing. That'll probably speed renders up by a lot.

I can't remember if this was said but does it do caustics? There was a movie of a fish tank on the yafray site I think with animated caustics that looked awesome. I was going to use it as a screensaver but it didn't loop.

^^OK, you just posted a new one so probably ignore most of what I said

.

JoOngle

I just discovered that it CAN do intersecting objects already!

You can bet I'm testing like mad right now.
Will be back with more cool stuff when I've pumped my processor to the limits...

Coalth

hmm... any windows version in sight?

JoOngle

More fun...

This is one Frame of the animation my computer is chewing on tonight!

I will upload it later today when it's done rendering in Yafray.

It consist of 125 frames, fluid-object resolution 100 and it took
my Athlon 30 minutes to render the 125 frame baking (for those who wants to know).

Patience....it's still rendering...

MyIS

Hmm, so it *can* do more detailed meshes... I saw the very blocky surface in your first videos and thought it was some sort of a limit. But not anymore!

_Aorus_

Looks awesome. I'm assuming the simulator will give control over things like viscosity and adhesive and cohesive qualities, right?

Timothy

Also is it possible to aply subsurf on the liquid objects? that would probably make it look alot better already.

JoOngle

Ok, here it is:

http://www.hamsterking.com/blender/3d/splaaaash.avi

It's a 4.6 mb file, but well worth watching

mrfranz

Nice animation ! This is so awesome !
When does a build for windows will be released ???
I can wait to test it.

ajc158

That looks great. This will indeed be a worthy addition for creating all those pointless water effects! Can't wait to try heavy rain with this baby...

Alex

Marty_D

wow, not too bad. You can adjust viscosity etc. up to inifinity?

[Kothe]

more!, more! I need more!

JoOngle

Yeah...fun, ain't it?

Right now there are some options. But most of the adjustments are "To-Do" as the
label says every time I want to adjust something...

So my guess is....it isn't implemented yet

Of course I'll make more experiments with it, just got to figure out how
to "save time" and make it look pretty at the same time.

As it is now...it seems like it's not possible to add modifiers such as "SubSurf".
It has it's own subsurf...sort of...where you can select Preview-resolution and Render-
resolution. Subsurf doesn't seem to have any effect at all...

Here is my contribution (hope you like it

):

Flythrough

Yafray and a domain size of 100^3.

Koba

P.S>Can't wait till someone has the patience/computing power to do a nice long fluid anim with caustics, GI and the whole lot.

when they release the win version i'll take it down campus and render it on the supers for a few hours - maybe I'll be able to get a hi-res anim done - still - even at such low quality (low quality - ha - it's pretty darn nice!) Jo-Onlges experiments are insane! keep it up!
