Water bubbles (rallenty water effect)

[Angel_Ice]

Hi all, i saw this web site http://www.renascent.nl/motion.htm

I refer to the video called "Eristoff Visual Arts", anyone can say if that is a "quick" way to do that cool water effect?
Is that a great use of particles in some appz like maya or 3d max? or it's just a rallenty fx of a rela water?(i think is't not a real water)...

some tipo to realize that kind of effect?

Many thanks to all!

It's made with After Effects.I think they used the Water Maelstorm and Water Utopia plugins from Panopticum.

[DDD]

could have been done as well in a 3d package use HV's or particles. I am leaning towards 3d for the actual effect then AE for the compositing and shine effect.

[Angel_Ice]

Cool, i take a look to taht plugs, I'll try also to do somethink in 3D....

where is my time?? oh my god...i have no time to do anythink...

[Angel_Ice]

Ditt0bx are u sure they have used that plugin? i saw some demos on panopticum web site, it seems that plugs are some kind of transiction efx, not much similar to the one seen on http://www.renascent.nl/motion.htm.

Maybe it's def a 3d particles like said DDD

[ditt0]

Well, they might have used something else, i can't know that for sure.What i know is that it can be done with Panopticum plugins . They are for transitions, but they are used best for transitions between motion files.That way, you would have a water move from the bottom left and another one wider from the middle with a vortex effect and transition applied.
And, yes, i think it can be done with particles too.Well, the possibilities are endless, i guess.

looks like meta ball particles with a vortex displacer and a glass texture. Then rendered with raytracing and invisible hdri reflections. Then a blue tint modifyer in after effects.

hmmm....i'll try to do somethink on both ways, i'll download a demo of that plugs and see what i can do, many thanks to all ya!

Hi Nirvana, can u explain me how to do that u said in maya?

[3d Nirvana]

Yep I did it in Maya. You can buy Maya at it's new price (they just lowered it half-price) at www.alias.com (http://www.alias.com)

Here's how I did it:

I have a directional emitter placed in the center of my stage. I have three Newton forces set up in random areas around the emitter. With the conserve set to one, and each Newton force with a slightly different magnitude, the particles will oscillate around the strongest force until they are shot out far enough that a different force will start affecting it. With proper tweaking the particles will swarm like bees between the three Newton forces. To add more of a swirling effect I created a vortex force on top of my emitter. I then set the vortex's range of power to a sphere so that the particles would swirl around to the point where they are knocked out of the sphere where the Newton force closest to the particles will pull them back and start the process over.

To create the material I connected a facing ratio's output to the input of the transparency channel to the input of my marital. From here you can tweak the colors to give you the desired bubble/water effect.

To create the hard glow towards the center of my particles I made a omni light in the center of my scene. I made the intensity extremely high. Then I gave it a linear falloff so it would not make the whole scene blindingly bright.

Lastly I added motion blur in my render attributes.

With tweaking of settings of the render attributes and the particles it comes out looking like the picture i made (http://www.kirupaforum.com/forums/showthread.php?t=76268). The animation of it looks just as good or better than the one you referenced at the top of this thread.

For extra effect you could also add a second emitter and repeat the above.

I'll post my finished animation up shortly, I rendered out a low quality version to see if it turned out the way I wanted. Tonight I am going to render the full length high quality version.

You can see my current picutre and soon to be the animation HERE (http://www.kirupaforum.com/forums/showthread.php?t=76268)
feel free to post a critique of it... hint hint.. wink wink

Cheers!

We would understand that better 3DN if you explained it in English plz :P

[3d Nirvana]

ok you create a particle maker thingy and make different pulling doohickys and a spinny thing and a bright shiney thingamabob.

beter ? :P

[Angel_Ice]

many thanks!

[Angel_Ice]

Ok, tryin to do what u said...

I made the directional emitter (i made also Blobby surface particles, right?).
I made the three newton fileds (magnitude: 3, 6, 10) -> when i play, the particles go stright ahead and they are not affected by the fields...why?

Don't understand how u did the colors and materials, sorry, can u explain better?
STill trying to do this, thanks for helping me!

[Angel_Ice]

Ok ok, so, i think i done thi frist problem:

Created the emitter, created the field (selct field + shift select the particles->fields->affect selected objects)...seems working good...

still can't do a good texture...

beter ? :P

Perfect descripion... look what I created from it :D ;P

[3d Nirvana]

Spimlistic-
Perfect descripion... look what I created from it
:bu:

[3d Nirvana]

Perfect descripion... look what I created from it :D ;P
rofl.. Nice one.... glad I could help :trout:

But for a actual "English version"... I made a particle emitter with 3 different forces that pull the particles towards them. I made it so the forces were balanced in a way that the particles go towards one then go towards the other and then to the other; and then start all over again. Then I added another force that spins the particles around when they are inside a defined area.

what do you guys think of the new font I used?

It looks like it'll take another day to render the animation, i checked it this morning and I had 4000 .tga files that were all black :crying:

Hope you get it to work Angel_Ice!

Cheers!

Nirvana, can u explain me bettere how to make the materials?

I haver antoher problem with the particles: first they are attacted by the first field(magnitudo 10), but they do a big circle around (i don't know if it's right) so they orbit around it 2 times and becoming be attracted from the second field (magn: 8), at this point, some particles continue to be attrcated by the first field, and others are attracted by the second filed...the same woth the third field...

the reslut is a very confusional animation...

so, this is of course it's the first time i do this...i'll do my best to make it work good but can understand how make the material.

What kind of rendering u made? Mental Ray?

[3d Nirvana]

Ok I’ll try explaining again for the texture:
You create a facing ratio parameter, in your hypergraph window. Then you click on the output of the facing ratio to the input of a gradient, then on the output of that to the input of your transparency channel on your main texture. It's kind of hard to explain without being able to guide your mouse on your computer.

Your animation sounds like it's working almost the way it should, mess around with your magnitudes a little and it should work better.

I used the Default Scanline Render, unlike with most of my newer work, simply due to the time it would take if I used Mental Ray.

Hope you get it working,
3dnirvana

LoL... I think you're just saying stuff... makin up words I mean... really hypergraph... come on :P

[DDD]

nah for real, hypergraph is real. Its right next to the "flux capacitor"

[3d Nirvana]

haha yah u guys got me :liar:

How did you know DDD? It IS right next to the flux capacitor!!!!

no seriously tho the hypergraph is the relationship editor. I ment to say Hypershade, which is the texture editor... sry Ice

http://www.3dnirvana.com/ForumPics/Hypershade.jpg
NOTE: The flux capacitor does not actually exist... I just photoshoped that in for the fun of it :P

[3d Nirvana]

Angel Ice- Here is a screenshot of my hypershade window with the 3 things connected, thought it might help a little.

there's a line blue line connecting to the ramp and a green one to the material... it's kinda hard to see. THe little arrows in the bottom corner of the textures are the input output nodes.

Hope this helps,
3dnirvana

[Angel_Ice]

Many thanks 3D Nirvana for your time and sharing your knowledge. I'll try to do my best now...u helped me a lot...now is time to work hard by my self in this project.
Have a nice day!

[simplistik]

LoL flux capacitor... what's that from? Back to the Future?

GJ, 3DN nice of you to share the knowledge

[3d Nirvana]

hey ice.... wana vote for me in the aids awairness contest.... ;) :beam: :smirk: :ponder:

[Angel_Ice]

I'll go to see...and if like..i'll vote :-)
