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
eyethe eye to update.
posthe 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.

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