how to get a wavy look like this

hi everyone i'm kinda newbie in grasshopper , i wanna know what would be the best approach to get a shape like the following image ?

i've come up with some stuffs by having some series of points in vertical direction, controlling them by sine waves(vertically, horizontally) through graph mapper and making a interpolate curve out of them .. but it's not exactly what i want .. i used some BREPS to pick the points and make them stand out but haven't reached to a decent curvature and look like this ..

you're technical opinions are so much welcomed and appreciated.. thanks a lot for your time..

Those waves look hand-made to me. Either someone did some 3D modelling, or they painted a heightfield bitmap which was imported.

thanks for the reply .. dont you think they might be some curves that are getting those points ? something like curves closet points .. ? but if you move the selected points through this, points will be flat .. something like "soft selection kinda thing is needed in this i guess .. is there any way to do soft selection in grasshopper ?

Maybe, but it seems to me the waves are not symmetrical on either side of the peak. They are much steeper on one side than the other. This to me indicates a manual approach as it would be very difficult to encode that property using some equation (especially since the falloff ratio isn't constant across the design as a whole).
