void Ocular::Math::Matrix3x3::getCol	(	uint32_t	index,
		Vector3< float > &	col
	)		const

Retrieves the value of a single column of the matrix.

Parameters

[in]	index	Column index [0, 3)
[out]	col	Vector to store the column values

void Ocular::Math::Matrix3x3::getData ( float * data ) const

Retrieves the matrix data values as an array of floats.

Parameters

[out] data An array of at least 9 floating point values (if more, only the first 9 are filled).

float Ocular::Math::Matrix3x3::getElement ( uint32_t index ) const

Returns an individual element of the matrix. Matrix elements are ordered as follows:

{rotX.x, rotX.y, rotX.z, rotY.x, rotY.y, rotY.z, rotZ.x, rotZ.y, rotZ.z}

or

0 3 6
1 4 7
2 5 8

Parameters

[in] index Element index to retrieve.

Returns: Element value at the specified index.

Matrix3x3_Internal * Ocular::Math::Matrix3x3::getInternal ( ) const

For internal use only. Only modify this pointer if you want your application to crash.

void Ocular::Math::Matrix3x3::getRow	(	uint32_t	index,
		Vector3< float > &	row
	)		const

Retrieves the value of a single row of the matrix.

Parameters

[in]	index	Row index [0, 3)
[out]	row	Vector to store the row values

void Ocular::Math::Matrix3x3::setCol	(	uint32_t	index,
		Vector3< float > const &	col
	)

Sets the value of a single column of the matrix.

Parameters

[in]	index	Column index [0,3)
[in]	col	Vector of column values

void Ocular::Math::Matrix3x3::setData ( float const * data )

Sets the matrix data values from an array of floats.

Parameters

[in] data An array of at least 9 floating point values (if more, only the first 9 are used).

void Ocular::Math::Matrix3x3::setElement	(	uint32_t	index,
		float	value
	)

Sets an individual element of the matrix. Matrix elements are ordered as follows:

{rotX.x, rotX.y, rotX.z, rotY.x, rotY.y, rotY.z, rotZ.x, rotZ.y, rotZ.z}

or

0 3 6
1 4 7
2 5 8

Parameters

[in]	index	Element index to set [0, 9)
[in]	value	Value to set the element to

void Ocular::Math::Matrix3x3::setRow	(	uint32_t	index,
		Vector3< float > const &	row
	)

Sets the value of a single row of the matrix.

Parameters

[in]	index	Row index [0,3)
[in]	row	Vector of row values
