How to create concentric circle ripples in an upright emissions image plane, in cycles? I would like to create a concentric circle ripple effect in an upright emissions image plane.  I have already tried a haphazard method using an invisible torus and sphere, and making the image plane a pinned cloth, which has created a modest ripple.  I have a screencast video of this but I am currently not sure how to imbed the video in this question, and the ripple really is not even noticeable in a still image:



Here is the setup:



There is a torus that becomes larger, and then a sphere is sent through the image which has a cloth modifier.



I was unable to figure out how to use displace modifier, wave modifier, or fluid to achieve a good effect.  But i am sure there is a better way to do this, possibly using nodes.

I would prefer if the edges stayed within the original confines of the image, but this is not 100% critical.

The ripple could be 3D or 2D (some kind of image disruption using nodes, or maybe something I know nothing about yet!).  I am interested in any possible solution!!!  The more I can learn, the better.

EDIT:

The difficulty here is making the ripple visible on an emissions image plane, from the front.  The 3D ripple would have to be at an outward angle to obscure the image as the wave expands, or it would have to stretch the image visibly as it moves outward...and be visible from the front!  Right now the wave modifier is not visible from the front even at its most extreme, but perhaps there is a way to make that work, and I am not aware of it yet!

Thank you!
Have your tried the Wave Modifier? Play the animation afterwards to see the effect
