Properties

elements

elements: number[]

A vector of length 9, containing all matrix elements.

Methods

copy

copy(matrix: Mat3): Mat3

- Defined in math/Mat3.ts:261
Copy another matrix into this matrix object.

Parameters
- matrix: Mat3
Returns Mat3

e

e(row: number, column: number): number
e(row: number, column: number, value: number): void

- Defined in math/Mat3.ts:247
Get an element in the matrix by index. Index starts at 0, not 1!!!

Parameters
- row: number
- column: number
Returns number
- Defined in math/Mat3.ts:248
Parameters
- row: number
- column: number
- value: number
Returns void

getTrace

getTrace(target?: Vec3): Vec3

- Defined in math/Mat3.ts:70
Gets the matrix diagonal elements

Parameters
- target: Vec3 = ...
Returns Vec3

identity

identity(): void

- Defined in math/Mat3.ts:26
Sets the matrix to identity

todo
Should perhaps be renamed to setIdentity() to be more clear.

todo
Create another function that immediately creates an identity matrix eg. eye()

Returns void

reverse

reverse(target?: Mat3): Mat3

- Defined in math/Mat3.ts:285
reverse the matrix

Parameters
- target: Mat3 = ...
  
  Target matrix to save in.
Returns Mat3
The solution x

scale

scale(vector: Vec3, target?: Mat3): Mat3

- Defined in math/Mat3.ts:151
Scale each column of the matrix

Parameters
- vector: Vec3

setRotationFromQuaternion

setRotationFromQuaternion(q: Quaternion): Mat3

- Defined in math/Mat3.ts:386
Set the matrix from a quaterion

Parameters
