Summary

Public Member Functions

Public Member Function Name Description
Matrix3 () Defines a Matrix3 instance and initializes the 3 x 3 matrix data.
Matrix3 (T m00, T m01, T m02, T m10, T m11, T m12, T m20, T m21, T m22) Defines a Matrix3 instance and initializes the 3 x 3 matrix data.
~Matrix3 () A destructor used to delete the Matrix3 instance.
GetData () const const T Obtains the 3 x 3 matrix data.
Determinant () const T Obtains the determinant of the matrix.
Inverse () const Matrix3 Obtains the inverse matrix.
operator new (size_t size) void Overrides the new function.
operator delete (void *p) void Overrides the delete function.

Static Public Member Functions

Static Public Member Function Name Description
Rotate (T angle, const Vector2< T > &pivot) static Matrix3 Obtains a rotation matrix. After a matrix is rotated, its data is shifted leftwards by 15 bits. Therefore, the result data needs to be shifted rightwards by 15 bits.
Scale (const Vector2< T > &scale, const Vector2< T > &fixed) static Matrix3 Obtains the scaling matrix. After a matrix is scaled, its data is shifted leftwards by 8 bits. Therefore, the result data needs to be shifted rightwards by 8 bits.
Translate (const Vector2< T > &trans) static Matrix3< T > Obtains a matrix translation.
