use an attractor curve to adjust curves that are being lofted to create a "wavey" surface. I've attached a picture to show the end result. Right now i create all the curves and then loft them together to create a surface which could then have a rib definition applied to it, and it works, my problem is that this project is for a 80' section of wall with ribs that would be a few inches apart, so that is a ton of curves i have to change everytime i want to adjust the overall shape. So is it possible to have an attractor curve that instead of adjusting the spacing of shapes in plane with the curve, would create high points or low points perpendicular to the curve? Hopefully that makes some sense, i'm having trouble finding the words to explain it, the attached pictures should help.
Any advice on how to do this would be great. I hate being that guy but this project came up last minute and it seemed like something the Grasshopper help save a ton of time in as far as adjustments go.
Thanks,
Kyle

h kangaroo and have found one project that illustrates my idea exactly...
https://vimeo.com/88002087
So far my best attempt has been to use a gridded surface in which the lines of the grid are springs, with a rest length at 80% of their initial length. (call this grid A) This is to simulate as if the material has been stretched 120% of its resting dimensions.
I have been trying to anchor the springs to a secondary grid (Grid B, curves that will be deposited onto the material) at the points of intersection with grid A.
I am not sure if this is the best approach, maybe soapfilm would be better? although i require the boundary (grid B) to adapt also...
Any advice or attempts to explain how Taichi Kuma has done this in his video would be greatly appreciated.
Thanks…
A: Who created it? / Copyright?
B: Anyone have a larger resolution copy of this image (or a vector so I can do a large resize).
Long and short - I'm an artist and I'd like to make a quilt out of that image. I need a decent resolution copy of it so I can do a huge resize and get a 76" x 80" crop out of it. I've tried resizing it in Photoshop, but by the time it's large enough, the quality has dropped below what is usable for my needs.
Thanks in advance! I totally understand I'm relying on the kindness of strangers here. (Also if this is inappropriate to post - please delete. Thank you)

assume we want to format two numbers, one integer and a floating point value. The integer represents an index and it should appear inside square brackets, then we want the floating point number rounded to a maximum of 4 decimal places (but always using at least one decimal place, even if it's zero), and then, in parentheses a scientific notation representation using 8 decimal digits of the number.
So, assuming the index is 16 and the value is 47.280006208, what we are after is:
[16] 47.28 (4.72800062E+001)
To make this work, we need a formatting pattern that looks like:
[{0}] {1:0.0###} ({1:E8})
The square brackets, spaces and parenthesis are just part of the output, they have no meaning whilst formatting. Everything inside the curly brackets though will be replaced with a specific formatting of one of the values.
When using the Format component as shown above, the formatting pattern is just text data. The component knows that it is supposed to use the Format() function using the pattern text and whatever additional data is provided.
When you invoke the Format() method in an expression, you do need to make sure that the pattern is actually text:
So here the pattern needs to be encased in double quotes, otherwise it will be treated as code, rather than text.
You cannot use the formatting method in the internal expression of a number parameter, because this method returns text, whereas the number parameter is only capable of storing numbers. Any expression that you put into a number parameter had better return numbers as a result.…

here are my questions.
1. The difference in general attractor transition is that, i only want the points are moving toward x axis, so if i just have ONE curve to distinguish, which is'nt the problem to find points location are in the right of left side of curve, but if i have TWO or THREE curves need to be distinguished, that is totally confused to me!
2. The points near curve which moved too big, how can i make it more equal?
3. I hope all the points can stay in the square boundary.
If anyone can give me some hint, i would be very appreciate with that.
thanks a lot!!
Shaun
