Animate Crumple / Water

Hello All,
Working on some water that I would love to animate.
Made a plane, crumpled, added water texture.
Is there a way to animate the crumple?
In a perfect world I pick first key frame crumple. Pick another key frame and crumple again and then the water animates. I tried this with no success. Anyone have any luck animating crumples or water?
Thanks
 
I think the *best* way to animate water in C3D would be using a script. In the good old days there was a UV Mapping modifier which (I believe) you might have been able to animate, which -- combined with displacement -- could have achieved something of what you're after (but only fairly badly).

It would also be nice if moving the displacement modifier around had the obvious effect, but it doesn't.

A better option would be a script which would generate/modify a planar mesh displacing by two differently angled sine-waves (or arbitrary height maps) to simulate "swell" and "chop" (i.e. long distance wave motion and ripples caused by wind). This would run quite nicely if used in concert with a subdivision modifier (so the script doesn't have to process an ungodly number of vertices).

And now for my disgusting kludge hack workaround. Use displacement, and move the plane around :)

You can get the C3D file here:

You'll also need this for the displacement map:

And watch the video here (just proof of concept):

This file uses my concrete texture, which is part of the 25 Free Textures:

Thanks podperson
I have played with some morphing of the surface and came up with a very rough working model.
I tried the links in your post but they were a little bit off.
first one worked, second went to same, third one didnt :(

Here is a link to a render using the morph tag on a plane that is crumpled.

Had and HDR image also to see the difference.

Its workable but still a little fake looking.

I will try your script out and see.
Thanks

In addition to Frank's post, please have a look to the following posts here : http://cheetah3d.de/forum/search.php?searchid=52837
tg_jp's movie in the second thread is really nice, I think.
 
That is a nice water element, he says he did that animation using blender and rendered it in Cheetah.

I have tried that script and wanted a little more control but will play with it a little more.

Thanks for all the help.
 
I fixed the links but you were too quick for me ;-)

Todd's script is definitely the way go, especially if you're able to hack it to get exactly what you want.
