Detailed Description

The representation of one GPU.

The pipe object is responsible for maintaining GPU-specific and frame-specific data. The identifier passed by the configuration contains the version of the frame data corresponding to the rendered frame. The pipe's start frame callback synchronizes the thread-local instance of the frame data to this version.

Constructor & Destructor Documentation

eqPly::Pipe::Pipe ( eq::Node * parent ) [inline]

Construct a new pipe.

Version:: 1.0

Reimplemented from eq::Pipe.

Definition at line 50 of file share/Equalizer/examples/eqPly/pipe.h.

virtual eqPly::Pipe::~Pipe ( ) [inline, protected, virtual]

Destruct the pipe.

Version:: 1.0

Reimplemented from eq::Pipe.

Definition at line 55 of file share/Equalizer/examples/eqPly/pipe.h.

Member Function Documentation

bool eqPly::Pipe::configExit ( ) [protected, virtual]

De-initialize this pipe.

Version:: 1.0

Reimplemented from eq::Pipe.

Definition at line 57 of file eqPly/pipe.cpp.

References eq::Pipe::getConfig(), and eq::Config::unmapObject().

Here is the call graph for this function:

bool eqPly::Pipe::configInit ( const eq::uint128_t & initID ) [protected, virtual]

Initialize this pipe.

Parameters:

initID the init identifier.

Version:: 1.0

Reimplemented from eq::Pipe.

Definition at line 45 of file eqPly/pipe.cpp.

References eq::Pipe::configInit(), eq::Pipe::getConfig(), and eq::Config::mapObject().

Here is the call graph for this function:

void eqPly::Pipe::frameStart	(	const eq::uint128_t &	frameID,
		const uint32_t	frameNumber
	)		`[protected, virtual]`

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:
