Public Member Functions

 Matrix3 () noexcept
 Construct an identity matrix.
 
 Matrix3 (const Matrix3 &matrix) noexcept=default

 Matrix3 (float v00, float v01, float v02, float v10, float v11, float v12, float v20, float v21, float v22) noexcept
 Construct from values.
 
 Matrix3 (const float *data) noexcept
 Construct from a float array.
 
Matrix3operator= (const Matrix3 &rhs) noexcept=default
 Assign from another matrix.
 
bool operator== (const Matrix3 &rhs) const
 Test for equality with another matrix without epsilon.
 
bool operator!= (const Matrix3 &rhs) const
 Test for inequality with another matrix without epsilon.
 
Vector3 operator* (const Vector3 &rhs) const
 Multiply a Vector3.
