Renderer.bounds

Description

The bounding volume of the renderer (Read Only).

This is the axis-aligned bounding box fully enclosing the object in world space.

Using bounds is convenient to make rough approximations about the object's location and its extents. For example, the center property is often a more precise approximation to the center of the object than Transform.position, especially if the object is not symmetrical.

Note that the Mesh.bounds property is similar but returns the bounds of the mesh in local space.

var rend: Renderer;

function Start() {
	rend = GetComponent.<Renderer>();
}


// Draws a wireframe sphere in the scene view, fully enclosing
// the object.
function OnDrawGizmosSelected() {
	// A sphere that fully encloses the bounding box.
	var center = rend.bounds.center;
	var radius = rend.bounds.extents.magnitude;

	Gizmos.color = Color.white;
	Gizmos.DrawWireSphere(center, radius);
}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Renderer rend;
    void Start() {
        rend = GetComponent<Renderer>();
    }
    void OnDrawGizmosSelected() {
        Vector3 center = rend.bounds.center;
        float radius = rend.bounds.extents.magnitude;
        Gizmos.color = Color.white;
        Gizmos.DrawWireSphere(center, radius);
    }
