Detailed Description

A Pipe represents a graphics card (GPU) on a Node.

All Pipe, Window and Channel task methods are executed in a separate co::Worker thread, in parallel with all other pipes in the system. An exception are non-threaded pipes, which execute their tasks on the Node's main thread.

Constructor & Destructor Documentation

EQ_API eq::Pipe::Pipe ( Node * parent )

explicit

Construct a new pipe.

Version: 1.0

virtual EQ_API eq::Pipe::~Pipe ( )

virtual

Destruct the pipe.

Version: 1.0

Reimplemented from eq::fabric::Pipe< Node, Pipe, eq::Window, PipeVisitor >.

Member Function Documentation

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

protectedvirtual

De-initialize this pipe.

Version: 1.0

virtual EQ_API bool eq::Pipe::configInit ( const uint128_t & initID )

protectedvirtual

Initialize this pipe.

Parameters

initID the init identifier.

Version: 1.0

virtual EQ_API bool eq::Pipe::configInitSystemPipe ( const uint128_t & initID )

protectedvirtual

Initialize the OS-specific pipe.

See also: setSystemPipe()

Version: 1.0

virtual EQ_API MessagePump* eq::Pipe::createMessagePump ( )

virtual

Create a new MessagePump for this pipe.

At most one message pump per execution thread is created. Each pipe render thread creates one message pump for its window system. The process main thread creates a message pump for AGL pipes and non-threaded pipes. Applications which do their own message pumping outside of Equalizer should return 0 here.

Returns: the message pump, or 0.

Version: 1.0

virtual EQ_API void eq::Pipe::frameDrawFinish	(	const uint128_t &	frameID,
		const uint32_t	frameNumber
	)

protectedvirtual

Finish drawing.

Called once per frame after the last draw operation. Releases the local synchronization if the thread model is draw_sync (the default).

Parameters

frameID	the per-frame identifier.
frameNumber	the frame to finished with draw.

Version: 1.0

virtual EQ_API void eq::Pipe::frameFinish	(	const uint128_t &	frameID,
		const uint32_t	frameNumber
	)

protectedvirtual

Finish rendering a frame.

Called once at the end of each frame, to do per-frame updates of pipe-specific data, for example updating the rendering engine. Releases the local synchronization if the thread model is local_sync. Always releases the global synchronization for this pipe.

This method has to call releaseFrame().

Parameters

frameID	the per-frame identifier.
frameNumber	the frame to finish.

Version: 1.0

virtual EQ_API void eq::Pipe::frameStart	(	const uint128_t &	frameID,
		const uint32_t	frameNumber
	)

protectedvirtual

Start rendering a frame.

Called once at the beginning of each frame, to do per-frame updates of pipe-specific data, for example updating the rendering engine. Waits for the node to start the frame, unless the thread model is async. If the thread model is async, the local synchronization is released immediately.

This method has to call startFrame().

Parameters

frameID	the per-frame identifier.
frameNumber	the frame to start.

Returns: true if this pipe is running, false otherwise.

Version: 1.0

Version: 1.11

virtual EQ_API bool eq::Pipe::processEvent ( const Event & event )

virtual

Process a received event.

The task of this method is to update the node as necessary, and transform the event into a config event to be send to the application using Config::sendEvent().

Parameters

event the received event.

Returns: true when the event was handled, false if not.

Version: 1.5.2

EQ_API void eq::Pipe::releaseFrame ( const uint32_t frameNumber )

protected

Signal the completion of a frame to the parent.

Parameters

frameNumber the frame to end.

Version: 1.0

EQ_API void eq::Pipe::releaseFrameLocal ( const uint32_t frameNumber )

protected

Release the local synchronization of the parent for a frame.

Parameters

frameNumber the frame to release.

Version: 1.0

virtual EQ_API WindowSystem eq::Pipe::selectWindowSystem ( ) const

protectedvirtual

Choose the window system to be used by this pipe.

This function determines which of the supported windowing systems is used by this pipe instance.

Returns: the window system currently used by this pipe.

Version: 1.0

EQ_API EventOCommand eq::Pipe::sendError ( const uint32_t error )

Send a pipe error event to the application node.

Parameters

error the error code.

Version: 1.7.1

EQ_API void eq::Pipe::setSystemPipe ( SystemPipe * pipe )

Set the system-specific pipe implementation.

The system-specific pipe implements the window-system-dependent part. The os-specific pipe has to be initialized.

Version: 1.0

protected

Start a frame by unlocking all child resources.

Parameters

frameNumber the frame to start.

Version: 1.0
