Does anyone knows how to make one of these? I am really trying my best, but somehow can’t figure it out…  
I have to do this as a project in uni. I have to include the pattern in a letter.

I would very much appreciate your help! Thank you very much!

In theory this is a height field

Start with size(…P3D);

Then make a grid of points PVector that you can connect with lines

beginShape would also be possible

Now x and z position of each point is fixed. Y is your actual data/value/height

Start with a random y value

Or set a sinus on it

Now maybe look at example for noise 3D

Also the points might be loosely connected like with springs- see example spring

Search here for 3D

Maybe this is interesting

Your problem is that you have global variables – in particular, speed (fart) – that you keep incrementing, until the number is so large your sketch doesn’t work anymore. Try bouncing that value around between -1 and 1, for example: float gridcelleStr =8; float gridBredde; float gridHoejde; float faktor = 2; float fart; float fart\_diff = 0.0000002; float xPos; float yPos; float tal; float strFaktor = 30; void setup() { size(1200, 1200, …
