Detailed Description

An Observer looks at one or more views from a certain position (head matrix) with a given eye separation.

Multiple observer in a configuration can be used to update independent viewers from one configuration, e.g., a control host, a HMD and a Cave.

Member Enumeration Documentation

enum eq::Observer::DirtyBits [protected]

The changed parts of the object since the last pack().

Subclasses should define their own bits, starting at DIRTY_CUSTOM.

Reimplemented from eq::Object.

Member Function Documentation

void eq::Observer::setEyeBase

(

const float

eyeBase

)

Set the eye separation of this observer.

Definition at line 76 of file lib/client/observer.cpp.

References eq::Object::setDirty().

Referenced by eq::server::Observer::Observer().

Here is the call graph for this function:

Here is the caller graph for this function:

float eq::Observer::getEyeBase

(

)

const [inline]

Returns:

the current eye separation.

Definition at line 57 of file lib/client/observer.h.

void eq::Observer::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. 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

const Matrix4f& eq::Observer::getHeadMatrix

(

)

const [inline]

Returns:

the current head matrix.

Here is the caller graph for this function:

VisitorResult eq::Observer::accept

(

ObserverVisitor &

visitor

)

Traverse this observer using a observer visitor.

Parameters:

visitor

the visitor.

Returns:

the result of the visitor traversal.

Here is the call graph for this function:

void eq::Observer::deregister

(

[virtual]

Deregister this observer from its net::Session.
