    • Method Detail

      • ContAlignedBox

        public static Box3f ContAlignedBox​(int iQuantity,
                                   Vector3f[] akPoint)
        Compute the smallest axis-aligned bounding box of the points.
        Parameters:
        iQuantity - number of points
        akPoint - points to examine
        Returns:
        bounding box

      • ContOrientedBox

        public static Box3f ContOrientedBox​(int iQuantity,
                                    java.util.Vector<Vector3f> kMeshVertices)
        Compute an oriented bounding box of the points. The box center is the average of the points. The box axes are the eigenvectors of the covariance matrix.
        Parameters:
        iQuantity - number of points
        kMeshVertices - vertices to examine
        Returns:
        bounding box

      • InBox

        public static boolean InBox​(Vector3f rkPoint,
                            Box3f rkBox)
        Test for containment. Let X = C + y0*U0 + y1*U1 + y2*U2 where C is the box center and U0, U1, U2 are the orthonormal axes of the box. X is in the box if |y_i| <= E_i for all i where E_i are the extents of the box.
        Parameters:
        rkPoint - point to test for containment
        rkBox - box container
        Returns:
        true if rkPoint is inside rkBox

      • MergeBoxes

        public static Box3f MergeBoxes​(Box3f rkBox0,
                               Box3f rkBox1)
        Construct an oriented box that contains two other oriented boxes. The result is not guaranteed to be the minimum volume box containing the input boxes.
        Parameters:
        rkBox0 - first box to merge
        rkBox1 - second box to merge
        Returns:
        merged box
