so in my sketch i change the distance between points randomly. sometimes you can almost see a perfect line , other a dotted line.

I want that even with very big distances between points, the points are always simetric in relation to the half of the width of the screen.

Here`s an image to illustrate my point.

Any tips ?

Thanx !

Yes, a few fixes.

1) Make sure rand starts as a non-zero value, to avoid a divide-by-zero.

float rand = 2;

2) Make sure rand is never allowed to be zero.

rand = random(2,80); // instead of random(80)

3) Replace your main drawing loop with this:

float margin = (width % distance) / 2;

for ( float i = margin ; i <= width-margin ; i += distance ) {

stroke (255);

strokeWeight(pointsize);

point (i, height* noise(i/100, time));

}
