constructor

new Matrix4(data: number[][]): Matrix4

- Defined in math/Matrix4.ts:179
Creates an instance of Matrix3.

memberof

Matrix4

Parameters
- data: number[][]
  
  The initial values for the matrx needs to be 3x3.
Returns Matrix4

Properties

data

data: number[][]

The data of the Matrix in a twodimensinal array.

memberof: Matrix4

Methods

To1D

To1D(): Float32Array

- Defined in math/Matrix4.ts:218
Returns a onedimensional representation for use in Shaders. Concatenates the rows.

Returns Float32Array

invert

invert(): Matrix4

- Defined in math/Matrix4.ts:231
Copied from the excercise and modified to suite my implementation!!!

Returns Matrix4

multiply

multiply(mat: Matrix4): Matrix4

- Defined in math/Matrix4.ts:200
Multiplies with another matrix to create a new instance.

If the current matrix is A and the one provided by mat is B then it's AB. Mind the order!

Matrix4

Parameters
- mat: Matrix4
Returns Matrix4

Static Frustum

Frustum(left: number, right: number, bottom: number, top: number, near: number, far: number): Matrix4

- Defined in math/Matrix4.ts:140
Constructs a new matrix that represents a projection normalisation transformation

Parameters
- left: number
  
  Camera-space left value of lower near point
- right: number
  
  Camera-space right value of upper right far point
- bottom: number
  
  Camera-space bottom value of lower lower near point
- top: number
  
  Camera-space top value of upper right far point
- near: number
  
  Camera-space near value of lower lower near point
- far: number
  
  Camera-space far value of upper right far point
Returns Matrix4

The resulting frustum matrix

Static Identity

Identity(): Matrix4

- Defined in math/Matrix4.ts:37
Returns the fourdim identity matrix. If row == col => 1 else => 0

Static LookAt

LookAt(viewpos: Vector3 | Vector4, center: Vector3 | Vector4, up: Vector3 | Vector4): Matrix4

- Defined in math/Matrix4.ts:113
Creates a LookAtMatrix.

Parameters
- viewpos: Vector3 | Vector4
  
  Position of the Viewer
- center: Vector3 | Vector4
  
  Position the camera is facing
- up: Vector3 | Vector4
  
  Vector that designates the updirection
Returns Matrix4

Static Perspective

Perspective(fovy: number, aspect: number, near: number, far: number): Matrix4

- Defined in math/Matrix4.ts:165
Constructs a new matrix that represents a projection normalisation transformation.

Parameters
- fovy: number
  
  Field of view in y-direction in radians!!!
- aspect: number
  
  Aspect ratio between width and height
- near: number
  
  Camera-space distance to near plane
- far: number
  
  Camera-space distance to far plane
Returns Matrix4

The resulting matrix

Static Rotation

Rotation(axis: Vector3 | Vector4, angle: number): Matrix4

- Defined in math/Matrix4.ts:66
Returns a Rotationmatrix for the specified axis and angle.

Parameters
- axis: Vector3 | Vector4
  
  The base axis for the rotation. One-hot encoded dimension => only one dimension is 1 the oners are 0.
- angle: number
  
  The angle to rotate in radians.
Returns Matrix4

Static Scale

Scale(v: number): Matrix4

- Defined in math/Matrix4.ts:98
Returns a scaling matrix. Only scaling of all dimesions allowed to preserve normals.

Parameters
- v: number
  
  Factor used for scaling.
Returns Matrix4

Static Translation

Translation(v: Vector3 | Vector4): Matrix4

- Defined in math/Matrix4.ts:51
Returns a Translationmatrix with the spezified parameters.

Parameters
- v: Vector3 | Vector4
  
  A 3 or 4 dimensional Vector that holds the desired translation parameters.
Returns Matrix4

Static Zero

Zero(): Matrix4

- Defined in math/Matrix4.ts:19
Returns an instance filled with zeros.
