I've created a noise function that pairs with a circle function to create a random noise circle thing that looks pretty cool. My problem is the curveVertex function in P5.js works correctly except for the connection of the first and last vertex. My code is:
let start = Array(50).fill(0); // dont change
let amount = 1; // amount of shapes
let gap = 30; // between shapes
let amplify = 50; // 0 -->
let colorSpeed = 1; // 1 - 9
let colorSeparation = 3; // 0 - 80 recomended 0 - 10
function setup() {
createCanvas(windowWidth, windowHeight);
for(let i = 0 ; i < start.length; i++){
start[i] = random(i);
}
}
function draw() {
background(0);
for(let dnc = (amount + 1) * gap; dnc > gap; dnc -= gap){
drawNoiseCircle(dnc, getNoise(start.length));
}
start = start.map( c => c + 0.01 );
}
function getNoise(amount){
let lengths = [];
for(let i = 1; i < amount + 1; i++){
let n1 = noise(start[i - 1]);
let noise1 = map(n1, 0, 1, -amplify, amplify);
lengths.push(abs(-noise1));
}
return lengths;
}
function drawNoiseCircle(radius, lengths){
colorMode(HSB);
fill(((frameCount + radius) * colorSeparation)/-map(colorSpeed, 1, 10, -10, -1) % 360, 100, 50);
noStroke()
let x;
let y;
beginShape();
for(let l = 0; l < lengths.length; l++){
x = Math.cos(radians(l * 360 / lengths.length)) * (radius + lengths[l]) + width/2;
y = Math.sin(radians(l * 360 / lengths.length)) * (radius + lengths[l]) + height/2;
curveVertex(x, y);
}
endShape(CLOSE);
stroke("black");
line(width/2, height/2, width, height/2);
line(width/2, height/2 + 9, width, height/2 + 9);
}<script src="https://cdn.jsdelivr.net/npm/p5@1.4.1/lib/p5.js"></script>I understand the endShape(CLOSED) closes the shape with a straight line, but I'm not sure any other way to close the shape.
You can see the pointed edge on the right side, directly in the middle of the shape.
!EDIT!
I've added lines to the shape to show the line segment that isn't affected by the curve vertex. Also, I understand it may not be a very significant problem, but if the amount of vertexes shrink, it becomes a much bigger problem (eg. a square or a triangle).
