The FromBoxes method is a static method of the BBox struct that creates a new bounding box that encompasses all the bounding boxes provided in the boxes parameter. This method is useful for calculating a bounding box that contains multiple other bounding boxes, effectively merging them into a single bounding box.
To use the FromBoxes method, pass an IEnumerable<BBox> containing the bounding boxes you want to merge. The method will return a new BBox that represents the smallest bounding box that can contain all the provided bounding boxes.
// Example usage of BBox.FromBoxes
var box1 = new BBox(new Vector3(0, 0, 0), new Vector3(1, 1, 1));
var box2 = new BBox(new Vector3(1, 1, 1), new Vector3(2, 2, 2));
var box3 = new BBox(new Vector3(-1, -1, -1), new Vector3(0, 0, 0));
var boxes = new List<BBox> { box1, box2, box3 };
BBox combinedBox = BBox.FromBoxes(boxes);
// combinedBox now represents the bounding box that contains box1, box2, and box3.
