I'm looking for ways to create ripple animations applied to objects. The idea is to create planar objects such as flags, pond/pool water surfaces with some movement. mimicking short or long ripples. Animated textures could do the trick, but the 3D shape remains flat and planar... any ideias on how to achieve this?
In my view image effects are preferable in normal see/water representation because they are less demanding on performance.

My kit for simple water image effects:

a demo: http://www.odisseia.univ-ab.pt/ABNet2/tutorials/water/Water_animation_demos/animatingSeaWater_textureCoordination.wrl
Shader effects:
Effects using shaders, even with no mesh movement, are impressive:

A nice, huge and very well done world. With good performance and uses the shader effects:

Mesh movements:
Here is an example, by Erny, using mesh movement:

a simple movement:

Thanks! Totally agree on the image effects and its lesser demands, but for a localized effect on a small object (i'm thinking a low-poly face) it might have a strong impact. Specifically, i'm thinking about the flag in the castle world...
and now to dive in (pun intended) in these examples...

Source files here with a vivaty studio file source (.fxw)

the zip package for the source files is empty. opened the vrml file in vrmlpad and as far as i could understand it (the code is still difficult for me, maybe this summer i can finally start to work with it) it's a proto declaration applyed to a texture?
and congratulations! those distributed virtual reality projects that are popping up look very nice!
Hi,
The zip file is corrected now.
Yes it uses an external proto. That is configured inside the vivaty st .fxw file.
Yet I should say that It is possible to create a more simple and single file by animating a sculpted surface (or other) with vivaty studio.

thanks! and now to look under the hood...
"Yet I should say that It is possible to create a more simple and single file by animating a sculpted surface (ou other) with vivaty studio" - deforming the mesh in an animation? using the animation node repositioning vertexes...? must try to see if works...
Since I could not find one online, made a small demo of an animated sculpted surface. It's entirely a Vivaty Studio creation (no outside protos).
The movement is achieved by animating the vertebras (spines) of the surface.

A more elaborated quick explanation text here. The demo's source files can be found here
All you guys, please post your animated surfaces so we see what you are doing out there
Enjoy!

Can't wait to tie up all the loose ends on the school network and finish all the meetings so that i can finally have time to dig in into this. Some ideas wich i have, beyond flags: a boat whose sails actually move...
Hi,
