intersectsRayDistance

  • intersectsRayDistance(ray: Ray): number

    参数

    • ray: Ray

      The ray.

    返回 number

    The distance to the intersection point, or -1 if there is no intersection.

    En

    Determines whether a ray intersects with the bounding sphere and returns the distance to the intersection point.

    Zh

    判断射线是否与包围球相交，并返回到交点的距离。

intersectsRayPoint

    参数

    • ray: Ray

      The ray.

    • outPoint: Vector3

      The intersection point.

    返回 number

    The distance to the intersection point, or -1 if there is no intersection.

    En

    Determines whether a ray intersects with the bounding sphere and returns the intersection point.

    Zh

    判断射线是否与包围球相交，并返回交点。
