Detailed Description

Designed to contain orientation (quaternion) data of the positional tracking.

Orientation is a vector defined as [ox, oy, oz, ow].

Constructor and Destructor

Orientation() [1/5]

Orientation

(

)

empty Orientation default constructor.

Orientation() [2/5]

Orientation

(

const Orientation &

orientation

)

Orientation copy constructor (deep copy).

Parameters

orientation

: the Orientation to copy.

Orientation() [3/5]

Orientation

(

const float4 &

in

)

Orientation copy constructor (deep copy).

Parameters

in	: the vector to copy.

Set in the following order : [ox, oy, oz, ow].

Orientation() [4/5]

Orientation

(

const Rotation &

rotation

)

Orientation constructor from an Rotation.

It converts the Rotation representation to the Orientation one.

Parameters

rotation

: the Rotation to be used.

Orientation() [5/5]

Orientation	(	const Translation &	tr1,
		const Translation &	tr2
	)

Orientation constructor from a vector represented by two Translation.

Parameters

tr1	: the first point of the vector.
tr2	: the second point of the vector.

Functions

operator()()

float operator()

(

int

x

)

Returns the value at specific position in the Orientation.

Parameters

x	: the position of the value

Returns

The value at the x position.

operator*()

Orientation operator*

(

const Orientation &

orientation

)

const

Multiplication operator by an Orientation.

Parameters

orientation

: the orientation.

Returns

The current orientation after being multiplied by the other orientation.

setRotationMatrix()

void setRotationMatrix

(

const Rotation &

rotation

)

Sets the orientation from a Rotation.

Parameters

rotation

: the Rotation to be used.

getRotationMatrix()

Rotation getRotationMatrix

(

)

const

Returns the current orientation as a Rotation.

Returns

The rotation computed from the orientation data.

setIdentity()
