Rain Drop - Water splash

Postby shaun_michael » Fri Dec 11, 2009 12:57 pm

Shaun What did you think of the solution of orozcoje?
How can we do something like that?

Like most problems there are often multiple approaches to the solution. Using geometry to control the shape is a viable option. Lets face it, if it gets the results you're after, then it's a perfect solution.

Starlighters solution is also viable, as is the scripting solution.

An important point to consider is how flexible is your chosen solution in terms of changing the set-up to get the results that you're being asked for? Can you control the height/width/number of crown points etc in order to customise it in a reasonable timeframe, or is it a solution that takes a rebuild for every example?

So you choose the solution method that best serves your ends.

Thanks to both of you.
I'll check that thread.
I'll post my test if they are worthy of it.
Cheers

Hello Shaun, Thanks for you words, and I will study those pages.

Vitor, your splash start looking really good.. keep it up.

Cheers.

A huge thanks to starlighter.
Still a WIP, but I'm close:

Hey Vitor.

Looks like your making progress on this project of yours. I am eager to see more results as they happen.

Keep up the good work.

I have to get results very fast because i have other shapes to do.
as you all can see in my studies in my vimeo page, i have to do an explosion of water an a splash, like that martini splash. I think this splash would be great for my initial scene. But i have to move on and get results quickly.

Besides i have to work on my fire also.

Some two new tests, this time i used a rounded vase, the effect was different from the image above but comparing it with the shape above with this when the "water" falls down it creates another shape going up. This was the best part comparing with the image above.



This shape here, as you all can see. In the image above I couldn't get it. Probably because of the container I think. I'm testing right now.
So what you guys think?
Probably I will not have the time to do it by scripting because of the other shapes I'm creating but I'm following luke advise an I'm studying the user guide, the python section.

Good progress.

A friend of mine is actually attempting to do something similar but for different purposes.

I ended up using a sphere with a fill object. filled it up about 0.1 or 0.2 in the Y axis.

I took the advice from a post in this thread on page one of setting your resolution to 2X what you would sim with, and then changing it back to half that.

So i entered 100 for RES, turned the fill object to "no" then "yes", then change the RES to 50 and hit simulate (with a locked simulation, a KSpeed set to limit and keep min 0 max 1.5.

I also used 2 Gravity Daemons,

One for the tiny drop of water, with 50 gravity, bounded to a rectangular shape (like the Computer Arts tutorial suggests),

And i got some interesting results.

Ill post some screen shots after work.

Good luck.


(After meshing a frame or two, I had no where near enough particles.)

Thanks a lot.
I'm checking your files right now.
I'ts a bit similar to what I made. I didn't use a sphere, I created a rounded plate in maya, cutting in half a sphere and exported to RF.
Now I'm testing and testing to see the best results possible.

Hey luke how is your script simulation going?
Cheers

Don't understand. everything is driving crazy in the simulation FA1Lure.
