Methods

add

add(v: Vector3 | Vector4): Vector4

- Defined in math/Vector4.ts:106
Returns a new Vector calculated by adding the given vector v to the current one.

memberof

Vector4

Parameters
- v: Vector3 | Vector4
Returns Vector4

cross

cross(v: Vector3 | Vector4): Vector4

Cross product Calculates the cross product using the first three components

Parameters
- v: Vector3 | Vector4
  
  The vector to calculate the cross product with
Returns Vector4

The result of the cross product as new Vector

distance

distance(v: Vector4): number

- Defined in math/Vector4.ts:87
Calculates the distance between this vector another one given as parameter.

memberof

Vector4

Parameters
- v: Vector4
Returns number

dot

dot(v: Vector3 | Vector4): number

- Defined in math/Vector4.ts:144
Dot product

Parameters
- v: Vector3 | Vector4
  
  The vector to calculate the dot product with
Returns number

The result of the dot product

length

length(): number

- Defined in math/Vector4.ts:76
Returns the length of the current vector. Only uses xyz and excludes w.

memberof

Vector4

Returns number

multiply

multiply(s: number): Vector4

- Defined in math/Vector4.ts:135
Returns a new vector with the coordinates multiplied by the parameter s. Only the xyz dimensions are multiplied.

memberof

Vector4

Parameters
- s: number
Returns Vector4

normalised

normalised(): Vector4

- Defined in math/Vector4.ts:94
Returns the normalised vector.

Returns Vector4

substract

substract(v: Vector3 | Vector4): Vector4

- Defined in math/Vector4.ts:120
Returns a new Vector calculated by subtracting the given vector v from the current one.

memberof

Vector4

Parameters
- v: Vector3 | Vector4
Returns Vector4

toVec3

toVec3(): Vector3

- Defined in math/Vector4.ts:196
Creates a threedimensional vector with the corresponding x,y,z-values, omits the w value.

Returns Vector3

transform

transform(mat: Matrix4): Vector4

- Defined in math/Vector4.ts:169
Calculates a new Vector by multiplying a Matrix with the current vector.

If x is the current vector and mat is A the resulting vector t is:

Ax = t
