iWave + Dynamic Paint!

Feb-13-2011    11 Comments

A couple of days ago I was playing with Blender ocean simulator modifier. While it's able to generate realistic wave motion, it's not able to interact with other objects.

Then I got an idea: what if I integrated a simple wave simulator with Dynamic paint!

So I ran across iWave algorithm by Jerry Tessendorf. I also discussed this with ZanQdo (Daniel Salazar) who was already implementing iWave for Blender through Python. We agreed that Dynamic Paint could be the best way to go, because it allows easy object interaction and is able to output textures as well as displacement.

iWave is a simple algorithm for simulating 2D water surface ripples/waves and their interaction with obstacles.


Now after a few days I already have a very basic iWave integration:

What you see here is an iWave surface interacting with Blender objects via Dynamic Paint. You should also note that it's just a normal mapped plane, so it's very fast to render!


Unfortunately, there is still lots of work to do before I can release a public test version... :s

Edit: An alternative wave algorithm, has been added to Dynamic Paint instead.

You are awesome! You are just reading my mind I'm planning a short movie right now and there was supposed to be a scene where I needed exactly this effect and I was wondering if I need to change the environment due to production issues. Seems like I won't have to :)! Thanks!

Thats very good indeed.
You sure are having a great run of ideas.
Dynamic paint is a great addition to the Blender tool set.

This is amazing work you are doing Miika,
Dynamic paint was awesome already... and implementing Jerry Tessendorf's and ZanQdo's work with it... Jaw dropping... Yoyu are always pushing the envelope

Thank you for all of your work.

cheers,

Andy

I was wandering if OceanSim and Dynamic paint could somehow interact - and, boom, here it is!
Exellent!

You seem to be going in the same direction as Farsthary did :). You're bringing one awesome feature after another to Blender. I hope you'll get rewarded with a job in that field if needed :)!

Wow! That is absolutely incredible. Nice job, especially after only such a short time. Really looking forward to a public release. Thank you for sharing.

Sheer brilliance! Blender 2.5/2.6 is going to be the utlimate 32 app with input from people like you

@Nion

No shrink effect there. It's actually a whole new canvas type, so no traditional effects are even available on iWave mode. :)

Why it's generating waves after object has moved on: I dunno. As far as I can tell it seems to be the only major issue with this iWave algorithm. I have been tweaking it and have managed to slightly reduce, but not completely remove those.
