The ClosestPoint method of the BBox struct calculates the closest point on the bounding box to a given point in 3D space. This method is useful for determining the nearest point on the bounding box's surface to a specified location, which can be helpful in collision detection, physics calculations, or spatial queries.
To use the ClosestPoint method, you need to have an instance of BBox and a Vector3 point for which you want to find the closest point on the bounding box. The method will return a Vector3 representing the closest point on the bounding box.
Note that the input parameter point is passed by reference, which means the method will not modify the original point but will use it to calculate the closest point on the bounding box.
// Example usage of BBox.ClosestPoint BBox boundingBox = new BBox(new Vector3(0, 0, 0), new Vector3(10, 10, 10)); Vector3 point = new Vector3(15, 5, 5); Vector3 closestPoint = boundingBox.ClosestPoint(ref point); // closestPoint will be (10, 5, 5) since it's the nearest point on the bounding box to the given point.
