I am designing a generative wreath. In it i want to randomly add a berry to the end of needles some of the time. However, the random() function is producing consistent patterns (see lines of berries in the image), usually in the same area as well as concentrating berries while leaving large areas without any. I have tried the following ways and they all produce similar results.

this is the pertinent code for the generation of branches and the vertex points in the branches are where the needles emerge from and the tip of the needle is the coordinate for the berry.

```
//start by making the underlying branches
for(int i=0; i<numBranch; i++){
float radius = minBranchRad + (i * 20);
//float radius = (minBranchRad + (i * 10)) + random(10, 35);
int resolution = floor(random(155,200)); //how many points along the circle path
float radInt = random(0.1, 1.2);
ArrayList<PVector> branchPts = new ArrayList<PVector>();
for(float angle=0.0; angle<TWO_PI; angle+=TWO_PI/resolution){
float xOff = cos(angle) * radInt + 1;
float yOff = sin(angle) * radInt + 1;
float radAmp = map(noise(xOff, yOff), -1.0, 1.0, 0.5, 1);
branchPts.add(new PVector(cos(angle) * radius * radAmp, sin(angle) * radius * radAmp, angle));
}
branches.add(new Branch(resolution, radius, branchPts));
}
//for each branch, make a corresponding number of needles
for(int j=0; j<branches.size(); j++){
Branch b = branches.get(j);
for(int k=0; k<b.ptCoords.size(); k++){
float nLength = random(45, 65); //get a length
float nAngle; //get an angle
if(k % 2 == 0){
nAngle = random(60, 80);
} else{
nAngle = random(100, 125);
}
int shade = colorArray[2];
boolean hasBerry = false;
if(randNormal() <= 0.38){
hasBerry = true;
}
needles.add(new Needle(j, nLength, nAngle, hasBerry, shade));
//basic random function
if(random(1) <= 0.173){
hasBerry = true;
}
//averaged random funciton
float randNormal() {
float sum = 0;
int div = 6;
for (int i=0; i<div; i++) {
sum += random(1);
}
return sum / div;
}
```

How can i get a more randomized result with few to no patterns and get full coverage?
