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.

virtual

Destruct this observer.

Version: 1.0

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

Member Function Documentation

virtual EQ_API bool eq::Observer::configExit ( )

protectedvirtual

Exit this observer.

Version: 1.5.2

Version: 1.5.2

virtual EQ_API 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

frameNumber the frame to start.

Version: 1.5.2

EQ_API ServerPtr eq::Observer::getServer ( )

Returns: the Server of this observer.

Version: 1.0

virtual EQ_API 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

command The event input command.

Returns: true if the event requires a redraw, false otherwise.
