Plane.setComponents()

The Plane.setComponents() method is used to set the components of a plane. A plane is a mathematical concept that defines an infinite, flat surface in three-dimensional space. In three.js, a plane is represented by a Plane object.

Syntax

setComponents(normal: Vector3, constant: number): Plane

The setComponents() method takes two arguments:

• normal: A Vector3 object representing the normal of the plane.
• constant: A number representing the distance of the plane from the origin.

The method returns the same Plane object that it was called on.

Example

const plane = new THREE.Plane();
const normal = new THREE.Vector3(0, 1, 0);
const constant = 0;

plane.setComponents(normal, constant);

In this example, a new Plane object is created. The setComponents() method is called on the plane object, passing in a normal vector of [0, 1, 0] and a constant of 0. This sets the components of the plane to be a flat surface that is parallel to the XZ plane and passes through the origin.

Notes

• The normal argument must be a normalized Vector3 object. If it is not normalized, the setComponents() method will normalize it before setting it as the plane's normal.
• The constant argument represents the distance of the plane from the origin along its normal vector. In other words, it determines where the plane intersects the Y-axis (in this example).
• The components of a plane can also be set using the Plane.set() method, which takes four arguments representing the components of the plane's equation: a, b, c, and d.
