Definition at line 58 of file fabric/observer.h.

template<class C, class O>

int32_t eq::fabric::Observer< C, O >::getOpenCVCamera ( ) const

inline

Returns: the current OpenCV camera.

Version: 1.5.2

Definition at line 97 of file fabric/observer.h.

template<class C, class O>

const std::string& eq::fabric::Observer< C, O >::getVRPNTracker ( ) const

inline

Version: 1.5.2

Definition at line 103 of file fabric/observer.h.

template<class C, class O>

EQFABRIC_INL void eq::fabric::Observer< C, O >::setEyePosition	(	const Eye	eye,
		const Vector3f &	pos
	)

Set the position of the given eye relative to the observer.

A standard symmetric eye setup uses (+-eyeBase/2, 0, 0).

Parameters

eye	the eye to update.
pos	the new eye position.

Version: 1.5.2

template<class C, class O>

EQFABRIC_INL void eq::fabric::Observer< C, O >::setFocusDistance ( const float focusDistance )

Set the focal distance.

See also: setFocusMode

Version: 1.1

template<class C, class O>

EQFABRIC_INL void eq::fabric::Observer< C, O >::setFocusMode ( const FocusMode focusMode )

Set the focal mode.

Version: 1.1

template<class C, class O>

EQFABRIC_INL bool eq::fabric::Observer< C, O >::setHeadMatrix ( const Matrix4f & matrix )

Set the head matrix.

The head matrix specifies the transformation origin->observer. Together with the eye separation, this determines the eye positions in the global coordinate system. The eye position and wall or projection description define the shape of the frustum and the channel's head transformation during rendering.

Parameters

matrix the matrix

Returns: true if the matrix was changed, false otherwise.

Version: 1.0

template<class C, class O>

EQFABRIC_INL void eq::fabric::Observer< C, O >::setOpenCVCamera ( const int32_t index )
