+/- Damped Sine Wave on Surface (ripples)

Hay,

Ive been trying to manipulate the [FORMul[a]RCH] ripples def to produce something like below.

You can see the start position of the top ripple left is below the surface and the start position of the bottom right is above.

I cant figure how to rewrite the definition to have 2 or more points start in different positions and affect each other on a surface.

Thanks

James

You can use these examples to figure what is the solution

Nice, thanks for the quick response. I didn't find either of those topics in my search attempts.

Lets see how this goes...

Cool, so after looking, reading and thinking about it I understood... that I didn't understand the equations used. My best guess is that you would manipulate the equation of one of the points to start the force as a negative? Well I tried adding minus' here there and everywhere to no avail... more minus', more reading, mo' theories...

Then I looked at David Ruttens comment Here (again) and saw the potential for some bastardization of my own...

Marginal success until you also look at...

I bet this could be fixed by using harmonious wave equations however, I can't make my mind up whether this is important or not, I've been toying with this problem for some time now (or its been toying with me) long before this post so its getting painfully old.

Scratch that, help me out! another push in the right direction would be appreciated, thanks

So this tweak gives me equal distortion with David Ruttens interferance definition which uses mass addition. But I was trying to get nearest neighbor to work with opposites. However I dont think this is possible (without adding an averaging result in the middle) which is a shame because I like this effect better.

On closer inspection of Nearest neighbor.gh if you up the resolution on the surface you can see a graphical line which is fine for two positive start points...but not so much for alternate waves. There is undoubtedly a way to average out the meeting point of the two/more points.
