    static public float getCirclePosition(float centerX, float centerY,
            float radius, float angleBegin, float angleEnd, int index,
            int totalNumber, boolean returnX) {
        float angle = angleBegin + (angleEnd - angleBegin)
                * (index / (float) (totalNumber - 1));
        if (returnX)
            return centerX + radius
                    * (float) Math.cos(angle * degreesToRadians);
