Declaration

public static Bounds CalculateBounds(Vector3[] positions, Matrix4x4 transform);

Parameters

positions	An array that stores the location of 3d positions.
transform	A matrix that changes the position, rotation and size of the bounds calculation.

Returns

Bounds Calculates the axis-aligned bounding box.

Description

Calculates the bounding box from the given array of positions and the transformation matrix.

Create a Project and add an empty GameObject called GameObject.
Add a 3D cube as a child of GameObject and call it Cube.
Add a LightProbeGroup component to Cube.
Add the script below to Cube.
Run the Project and switch back to the Scene view.

In the Scene view, you can see the LightProbeGroup. When the game runs, the rotation changes in Awake. The eight yellow spheres that indicate the LightProbeGroup change position and the Cube appears rotated. Scene mode shows the Cube rotated in the x, y and z axes, and shows in the Local tool handle. Rotating the Cube changes the positions of the eight LightProbeGroup Light Probes. The Scene mode rotates and zooms to show the Light Probes. Also, the Cube rotates and the LightProbeGroup updates. If you rescale the Cube, the LightProbeGroup changes size.

using UnityEngine;
using System.Collections;// GeometryUtility.CalculateBounds - example
public class Example : MonoBehaviour
{
    void Awake()
    {
        transform.position = new Vector3(0.0f, 0.0f, 0.0f);
        transform.Rotate(10.0f, 30.0f, -50.0f, Space.Self);
        Debug.Log(transform.localToWorldMatrix);
    }
    void OnDrawGizmosSelected()
    {
        LightProbeGroup lightProbeGroup = GetComponent<LightProbeGroup>();
        Vector3 center = transform.position;
        Bounds bounds = GeometryUtility.CalculateBounds(lightProbeGroup.probePositions, transform.localToWorldMatrix);
        Gizmos.color = new Color(1, 1, 1, 0.25f);
        Gizmos.DrawCube(center, bounds.size);
        Gizmos.DrawWireCube(center, bounds.size);
    }
