Limit Wave Effect to Area Around Droplet Center

I’m trying to create ripple-like waves around 3 droplet points…

This thread has many posts about “ripple” surfaces:

Adding Points to Ripple

The core algorithm hasn’t changed since I introduced the damped sine (actually cosine) Expression component, just making it better. Wouldn’t it be nice if it worked with multiple rectangles? Took a few little tweaks to get the code in proper Grasshopper fashion, but it does now. Dimensions are obtained from the rectangles, which may be supplied by any means and need not touch each other. To demonstrate, there is a white “two rectangles” group that creates two side by side: ripples_20…

Based on a “Damped Sine Wave Formula” from David Rutten:

There are many threads about “ripple” surfaces on this forum.
