A 4-dimensional vector.

Methods that manipulate values are generally destructive. To preserve the original values, explicitly call clone() to create a duplicate instance.

constructor

new Vector4(): Vector4
Creates an instance with all components initialized to 0.

Returns Vector4
new Vector4(x: number, y: number, z: number, w: number): Vector4

Methods

clone

clone(): Vector4
Clones the instance.

Returns Vector4

equals

equals(v: Vector4): boolean
Compares the vector to v, and returns true if they are approximately equal.
Parameters
- v: Vector4
Returns boolean

lerp

lerp(v: Vector4, a: number): this
Calculates the linear interpolation (lerp) between the current value and v, using a as the interpolation factor, then updates the vector's value to the result.
Parameters
- v: Vector4
- a: number
  The interpolation factor, specified as a number between [0, 1].
Returns this

set

set(x: number, y: number, z: number, w: number): this
Sets the vector's component values to those specified in x, y, z and w.
Parameters
- x: number
- y: number
- z: number
- w: number
Returns this
