Vector2

new Vector2(x?, y?)

THREE equivalent: THREE.Vector2

Two-component vector used for UV coordinates, 2D positions, and curve points.

Differs from THREE.js

mulScalar instead of multiplyScalar.

Properties

Name	Type	Description
x	number	X component.
y	number	Y component.
length	number	Euclidean length (read-only).
lengthSq	number	Squared length (read-only).

Methods

Method	Description
set(x: number, y: number): this	Sets both components.
add(v: Vector2): this	Adds another vector in place.
sub(v: Vector2): this	Subtracts another vector in place.
mulScalar(s: number): this	Multiplies both components by a scalar.
normalize(): this	Scales the vector to unit length.
dot(v: Vector2): number	Returns the dot product with v.
cross(v: Vector2): number	Returns the 2D cross product (scalar): xv.y - yv.x.
distanceTo(v: Vector2): number	Returns the Euclidean distance to v.
min(v: Vector2): this	Component-wise minimum.
max(v: Vector2): this	Component-wise maximum.
lerp(v: Vector2, alpha: number): this	Linear interpolation toward v by alpha.
clone(): Vector2	Returns a new Vector2 with the same components.
copy(v: Vector2): this	Copies components from another vector.
