如果两点之间的距离小于指定的距离，则生成直线而不是贝塞尔曲线

function generatePath(point1, point2, thresholdDistance) {
    const distance = Math.sqrt(Math.pow(point2.x - point1.x, 2) + Math.pow(point2.y - point1.y, 2));
    
    if (distance < thresholdDistance) {
        // 生成直线
        return `M${point1.x},${point1.y} L${point2.x},${point2.y}`;
    } else {
        // 生成贝塞尔曲线（以二次贝塞尔曲线为例）
        const controlPoint = {
            x: (point1.x + point2.x) / 2,
            y: (point1.y + point2.y) / 2
        };
        return `M${point1.x},${point1.y} Q${controlPoint.x},${controlPoint.y} ${point2.x},${point2.y}`;
    }
}

// 示例使用
const point1 = { x: 0, y: 0 };
const point2 = { x: 10, y: 10 };
const thresholdDistance = 15;

const path = generatePath(point1, point2, thresholdDistance);
console.log(path); // 输出路径字符串
