Grasshopper

algorithmic modeling for Rhino

Make a series of sine waves which gradually increase wavelength

I'm attempting to create a script which creates a series of sine waves where the amplitude remains constant, but the wavelength increases (exponentially maybe?) from the previous wavelength. Initially I'm trying to simply generate a curve which I can then loft in Rhino to make the 3D panel, but if I could generate the panel and its dimensions via Grasshopper that would be great too.

My end goal is to create a CNC routable panel that will clad below a heavy object, trying to visually show the compression forces of that object. 

I have attempted to modify a few scripts but fail to get the desired effect:

Thanks

Try this guy on for size (have a play with the points on the graph mapper to change the variation in wavelengths).

Hi Joe, thanks! I'm getting closer. This is what I've come up with so far along the same lines, however I did "extrude curve" manually in rhino.

I'm trying to figure a way to have more control, so that I could enter the total linear length of the sheet (34" in my case) and the amplitude (height of each curve), and maybe number of curves. Then I could play with a graph to get the level of "compression" that I'm looking for.

I'm getting closer. Thanks for your input!
