Scripting Example: Rose

This is an advanced feature: see Scripting Explained.

To make this print:

Use this script:

const rose = (centerX, centerY, stepCount, turns, n, d, A) => {

var results = [];

var k = n / d;

var stepSize = turns * 2 * Math.PI / (stepCount);

for (var theta = 0; theta < d * turns * 2 * Math.PI; theta += stepSize) {

var x = centerX + A * Math.cos(k * theta) * Math.cos(theta);

var y = centerY + A * Math.cos(k * theta) * Math.sin(theta);

results.push(x, y);

console.log(x);console.log(y);

}

return results;

};

foodini.useIngredient(ingredients[0]);

var X = 256/2, Y = 148/2, SIZE = 60, STEPS = 400, TURNS = 1;

[[5,4]].forEach((nd, i) => {

const pts = rose(X + 2 * (SIZE + 5)* i, Y, STEPS, TURNS, nd[0], nd[1], SIZE);

foodini.drawPolyline(pts,false,false);

});
