Detailed Description

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

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

Constructor & Destructor Documentation

eq::Observer::Observer ( Config parent)

Construct a new observer.

Version
1.0
virtual eq::Observer::~Observer ( )
virtual

Destruct this observer.

Version
1.0

Reimplemented from eq::fabric::Observer< Config, Observer >.

Member Function Documentation

virtual bool eq::Observer::configExit ( )

virtual void eq::Observer::frameStart ( const uint32_t  frameNumber)
protectedvirtual

Start rendering a frame.

Called once at the beginning of each frame before the Config::frame is send to the server, to do per-frame updates of observer-specific data.

Parameters
frameNumberthe frame to start.
Version

the Server of this observer.
Version
1.0
virtual bool eq::Observer::handleEvent ( EventICommand command)
virtual

Handle an event.

The event type and originator identifier (of this object) have already been consumed from the given command.

Parameters
commandThe event input command.
Returns
true if the event requires a redraw, false otherwise.
