Hello. I am trying to achieve some simple waves on a object in C4D.
I have an object traveling and turning around on a surface and would like to have som wakes from the object, that will fade out the further away from “wake generating object” they get.
Is there a way to reach this with only deformers or perhaps some python code?

My “vision” is something as nice as the wave world simulation i AE, but in C4D and without to expensive physics calculus

I have used displacement map and it looks ok, but only as a still image…
I also sculpted the waves, and it looks good, but I find it very hard to animate that…

So I am doing a longshot here

TIA, Carl Björndal

Hi Carl Björndal,

Here is a rough sketch. You might take it apart and configure it more to your liking of course.

The two Formula Effectors are the main part. Wave and Flag are more tiny supporters here.

The idea, if I understood the simulation correctly, the ship creates a main wave, along the axis of moment, and an ripple like arrow, based on interference of the lateral and the transversal wake, based on the forward movement and the ship shapes, pushing water to the side. My understanding of interference is, that there are two frequencies out of sync. so they produce more details. Perhaps more like harmonics. Either way, I guess the way to go is based on at least two deformer.

I have attached two more files, perhaps in each is a little bit of a solution or at least an idea to push it further.

Please let me know if there is any question. BTW, the 360 in the effector formula, can be increased or decreased for extreme speed up adjustments, then use the t slider for the fine tuning.

All the best

Alternative, with a helix as falloff:

Option two, just falloff waves

Sorry—I have obviously problems to upload files here at the moment.

P.S.: Perhaps this comes closer.

The key is certainly in a fine tuning of the three Effector-deformer, especially in the difference of the Cone-Shapes. With a nice set up, you could take the information as image and use it anywhere.

[With r18 you can place Effector Deformer into an Re-Effector and then again. As an result one can shape with different Falloff shapes a kind of Falloff Boolean. If there is an interst after r18 is shipping, please ask me, I’m happy to share an example.]

Thank you Dr. Sassi for your efforts!

I have been home with sick kids(still am), and therefore I am replying so late. I will try to test your solution as fast as I can.

In my search I found this old Soft Image discussion dealing with the same problem…
http://www.si-community.com/community/viewtopic.php?f=24&t=3851

It seams that they have an other way of solving this.

My best wishes for your kids.

Well, you wrote that you would NOT like to explore the calculus of it, as your initial post showed an Integral, but you asked for something more “practical”, with that I promise to share no antiderivatives.
You mentioned displacement but you seemed not happy with it either, so I excluded it here as well. Otherwise, I would have suggested perhaps the Formula Shader, but with the above mentioning, this is out of the window as well. OK, no word about this here at any time. Promise. :o)
. SoftImage is EOL [End Of Life] and ICE was certainly something that XPresso and/or Python in Cinema 4D can provide as well, different but certainly possible.
I guess you haven’t really researched this link, as the link inside of it results in a #404 for me. If you have some time, explore the four different ways I have provided, all without touching the Integral, as requested.

Cheers.
