Can you explain me what is these? (point, map, noise)

bb34 · October 2017

point(x, y + map(noise(x/150, y/150, z), 0, 1, -100, 100)) ;

It is setting a point in a 2D sketch

the base position is x,y

y get added a noise, which is a kind of random value

This noise gets a parameter 1/150th based on x,y

Since noise generates a value between 0 and 1 the value gets mapped from this range to a big range between -100 and 100

point is a square or circle the size of strokeWeight

noise / perlin noise
returns a number between 0 and 1 , from a position in a "cloud"

map turns number from one range to another, in this case 0,1 to -100,100

point( x , y +- 100 )

should be some kind of distortion on the y-axis ?

More simplified: point(x, y + 200*noise(x/150, y/150, z) - 100) ; B-)
