如何在JavaScript中找到圆上的交点？

function findCircleIntersections(x1, y1, r1, x2, y2, r2) {
    const d = Math.sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2);

    // 检查是否有交点
    if (d > r1 + r2 || d < Math.abs(r1 - r2)) {
        return []; // 没有交点
    }

    const a = (r1 ** 2 - r2 ** 2 + d ** 2) / (2 * d);
    const h = Math.sqrt(r1 ** 2 - a ** 2);

    const x0 = x1 + a * (x2 - x1) / d;
    const y0 = y1 + a * (y2 - y1) / d;

    const intersection1 = {
        x: x0 + h * (y2 - y1) / d,
        y: y0 - h * (x2 - x1) / d
    };

    const intersection2 = {
        x: x0 - h * (y2 - y1) / d,
        y: y0 + h * (x2 - x1) / d
    };

    if (d === r1 + r2 || d === Math.abs(r1 - r2)) {
        return [intersection1]; // 只有一个交点
    }

    return [intersection1, intersection2]; // 两个交点
}

// 示例
const intersections = findCircleIntersections(0, 0, 5, 4, 0, 5);
console.log(intersections);
