确定在HTML画布中绘制的直线和曲线之间的距离

// 计算直线距离
function calculateLineDistance(x1, y1, x2, y2) {
  return Math.sqrt(Math.pow(x2 - x1, 2) + Math.pow(y2 - y1, 2));
}

// 计算曲线距离
function calculateCurveDistance(curvePoints) {
  let distance = 0;
  for (let i = 0; i < curvePoints.length - 1; i++) {
    const x1 = curvePoints[i][0];
    const y1 = curvePoints[i][1];
    const x2 = curvePoints[i + 1][0];
    const y2 = curvePoints[i + 1][1];
    distance += calculateLineDistance(x1, y1, x2, y2);
  }
  return distance;
}

// 示例使用
const lineDistance = calculateLineDistance(0, 0, 3, 4);
console.log("直线距离：" + lineDistance);

const curvePoints = [[0, 0], [1, 2], [3, 4], [5, 6]];
const curveDistance = calculateCurveDistance(curvePoints);
console.log("曲线距离：" + curveDistance);
