Gear Curve

Code:

hyperbolicTan(theta) {
    let l = pow(e, 2 * theta);
    return (l - 1) / (l + 1);
}

gear() {
    for (let theta = 0; theta < 2 * PI; theta += 0.05) {
      let r =
        this.a +
        (1 / this.b) * this.hyperbolicTan(this.b * sin(this.m * theta));
      let x = this.r * r * sin(theta);
      let y = this.r * r * cos(theta);
      this.points.push(createVector(x, y));
    }
}
