Simple Ripple Mesh Deformation in Unity3d

This is a simple ripple simulator that I wrote for Unity3d. It uses a very simple bitmap algorithm to simulate rippling water. (ie no complicated FFT or physics simulations) It isn't super realistic, but it is good enough. (and it is fast)

Hello!This is really cool!

The mesh deformation happens on the GPU or on the CPU?Do you use a normal script or a shader to deform it?

@tedchirvasiu The mesh deformation is entirely done on the CPU using a normal script. I am actually moving the mesh vertexes every frame. If you check the link in the description i provide the code. Cheers!

It is not technically a physics simulation, just a clever bitmask manipulation that is translated into a mesh deformation. So to answer both your questions: not very processor intensive really., should work on just about anything. If you wanted to do the same thing with 'proper physics' it would be very very expensive. (which is why I went the 'fake' route :-)

@tauntingpanda Is there anyway to get a download of this? Like a prefab, or a script? It would be hella awesome and much appreciated.

@mbe102 Check out my other video: ripple effect test in unity 3d, it has a link in the description to my blog where you can download it :-)

TUTORIAL!!!!!!!!!!!!!!!!!!!!!!­!

@tauntingpanda How do you do bitmap manipulation in Unity? I'm looking to do something very similar.

@tauntingpanda how do you make water

I'm also interested in the Tornado Twins' question, and I do wonder if there's some way to incorporate it into simple physics...

nice looks cool
