Box3.set()

The Box3.set() method is used in the Three.js library to set the dimensions of a 3D bounding box. It is a member of the THREE.Box3 class, which represents an axis-aligned bounding box with minimum and maximum points.

Syntax

.set( min: Vector3, max: Vector3 ) : this

Parameters

• min: The minimum point of the bounding box, defined as a THREE.Vector3 object.
• max: The maximum point of the bounding box, defined as a THREE.Vector3 object.

Return Value

The set() method returns the modified Box3 object.

Description

The set() method is used to modify the minimum and maximum point coordinates of a Box3 object. This updates the dimensions of the bounding box and recalculates its center point and size.

If no parameters are provided to the set() method, the min and max points of the bounding box will default to (Infinity, Infinity, Infinity) and (-Infinity, -Infinity, -Infinity), respectively.

Examples

Creating a bounding box and updating its dimensions using Box3.set():

const boundingBox = new THREE.Box3();

const minPoint = new THREE.Vector3( -10, -10, -10 );
const maxPoint = new THREE.Vector3( 10, 10, 10 );

boundingBox.set( minPoint, maxPoint );

Notes

• The min and max vectors can be modified individually using the Box3.min and Box3.max properties.
• The Box3 class provides several other methods for updating and querying bounding box dimensions, including Box3.expandByPoint(), Box3.union(), and Box3.intersectsBox().
