Fluid Ink style animation problem

[LaszloFX]

Hello Everybody,

I'm trying to do a logo reveal animation. The effect I'm going for is an "ink flow in water"-like effect.

Here is a reference video of what I'm aiming to do:

So far I've made a quick test:

First, I scattered some points on a flat object.

Then I used a SOP solver, to have a procedural growth over time by specifying a starting point and based on the next nearest point I'm spreading my selection.

I also animated my Search Radius coming from my vopsop's pcOpen node inside the SOP solver, to make sure it will fill out the entire object.

Then I colored it to differentiate it and I just delete the non-selected points based on their color.

So my question is that first of all, is this a good way of trying to achieve this effect, or do you guys would have some other suggestions that might work better for this?

Because it would be great if I could get that kind of detail, that you can see in the reference video at 0:30 and 0:45.

What kind of noise should I use to get that kind of swirly detail, seen in the video?

Also it would be nice to have more control over the speed of the flow.

I attached my scene file.

Thank you very much in advance for your help!

I did something similar before using different approach:

I've used a pyro object in a 2D container and a sink object for the shape I was looking for.

The reason to use a smoke was the temperature that makes the smoke to expand outward from the center of the source.

Even though I've used different colors for every drops and those colors blended nicely caused by the temperature's difusion.

Then you could advect points by the smoke and convert to fluid to get that liquid looking effect.

I could upload a sample scene for you if you're interested.

cheers

Thank you very much for your reply Dobril!

I think your method will have a much better liquid like motion, which is closer to what I'm trying to achieve.

In my method I'm not a big fan of the motion itself.

I would love to check out your scene file if it's not too much trouble. Could you upload it please?

Thanks again!

I'm interested in seeing this example as well. Thank you!

sorry I was quite busy yesterday

I'll dig out the scene and upload it today

here you go:

maybe it's not exactly what you're looking for but hope it'd help to get you started

in this case I'm droping some particles onto a grid forming the letter "P" but you got a lot of options to control the numbers, size, speed, etc..

and render it out to see the colors:

sorry I've forgot the texture I'm using to form the shape:

Very nice setup! Thank you very much!

I will definitely try this out. I love the movement already.

Thanks again Dobril!
