Matrix3x3() [2/4]

AeonGames::Matrix3x3::Matrix3x3

(

const Transform &

aTransform

)

Constructor.

Parameters

aTransform

Transform from which to initialize the matrix. Only Scale and Rotation are used.

Definition at line 27 of file Matrix3x3.cpp.

Matrix3x3() [3/4]

AeonGames::Matrix3x3::Matrix3x3

(

const float *const

Construct from a float array.

Parameters

aMatrix

Pointer to a float array of at least 9 elements in column-major order.

Definition at line 31 of file Matrix3x3.cpp.

Matrix3x3() [4/4]

AeonGames::Matrix3x3::Matrix3x3

(

Member Function Documentation

GetInvertedMatrix3x3()

const Matrix3x3 AeonGames::Matrix3x3::GetInvertedMatrix3x3

(

)

Get the inverted matrix.

Returns

A new Matrix3x3 that is the inverse of this matrix.

Definition at line 56 of file Matrix3x3.cpp.

GetMatrix3x3()

const float *const AeonGames::Matrix3x3::GetMatrix3x3

(

)

const

Get a pointer to the internal matrix data.

Returns

Pointer to the 9 float elements of the matrix.

Definition at line 45 of file Matrix3x3.cpp.

GetRotationMatrix()

const Matrix3x3 AeonGames::Matrix3x3::GetRotationMatrix ( float angle, float x, float y, float z )

static

Constructs the rotation matrix defined by the axis-angle provided.

The Matrix returned is a 3x3 matrix constructed using the same formula glRotate* uses.

Parameters

angle	[in] Angle in degrees of rotation.
x	[in] X element of axis of rotation.
y	[in] Y element of axis of rotation.
z	[in] Z element of axis of rotation.

Returns

Rotation matrix.

Definition at line 101 of file Matrix3x3.cpp.

Invert()

Matrix3x3 & AeonGames::Matrix3x3::Invert

(

)

Invert this matrix in place.

Returns

Reference to this matrix after inversion.

Definition at line 50 of file Matrix3x3.cpp.

const float AeonGames::Matrix3x3::operator[]

(

size_t

aIndex

)

const

Access a matrix element by index.

Definition at line 95 of file Matrix3x3.cpp.
