Script Preparation code:

var N = 1000000;
var x = new Float32Array(N);
var y = new Float32Array(N);
var z = new Float32Array(N);

for (var i = 0; i < N; ++i) {
    x[i] = 100 * Math.random();
    y[i] = Math.random();
    z[i] = Math.random();
}

function calcTriangleCount(r, tolerance, zoom) {
    return Math.PI / Math.acos(1 - (tolerance * zoom) / r);
}

function calcSegments(r, tolerance, scale) {
    return 2 * Math.sqrt((2 * (r * scale)) / tolerance);
}
