Constructor & Destructor Documentation

eVolve::Channel::Channel ( eq::Window * parent )

Construct a new channel.

Reimplemented from eq::Channel.

Definition at line 35 of file examples/eVolve/channel.cpp.

References eq::Frame::BUFFER_COLOR, and eq::Frame::setData().

Here is the call graph for this function:

virtual eVolve::Channel::~Channel ( ) [inline, protected, virtual]

Destruct the channel.

Reimplemented from eq::Channel.

Definition at line 38 of file examples/eVolve/channel.h.

Member Function Documentation

bool eVolve::Channel::configInit ( const uint32_t initID ) [protected, virtual]

Initialize this channel.

Parameters:

initID

the init identifier.

Reimplemented from eq::Channel.

Definition at line 53 of file examples/eVolve/channel.cpp.

References eq::Channel::configInit(), EQINFO, eq::Channel::getUniqueColor(), and eq::Channel::setNearFar().

Here is the call graph for this function:

void eVolve::Channel::frameStart	(	const uint32_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 channel-specific data. This method has to call startFrame().

Parameters:

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

See also:: Config::startFrame()

Reimplemented from eq::Channel.

Definition at line 71 of file examples/eVolve/channel.cpp.

void eVolve::Channel::frameDraw ( const uint32_t frameID ) [protected, virtual]

Draw the scene.

Called 0 to n times during one frame.

Parameters:

frameID

the per-frame identifier.

Reimplemented from eq::Channel.

Definition at line 112 of file examples/eVolve/channel.cpp.

References eq::Channel::applyBuffer(), applyFrustum(), eq::Channel::applyHeadTransform(), eq::Channel::applyViewport(), eq::Channel::getPipe(), eq::Channel::getRange(), and eq::Channel::outlineViewport().

Here is the call graph for this function:

void eVolve::Channel::frameAssemble ( const uint32_t frameID ) [protected, virtual]

Assemble input frames.

Called 0 to n times during one frame.

Parameters:

frameID

the per-frame identifier.

See also:: getInputFrames

Reimplemented from eq::Channel.

Definition at line 247 of file examples/eVolve/channel.cpp.

References eq::Compositor::assembleFrame(), eq::Compositor::assembleFramesSorted(), eq::Frame::clear(), eq::Frame::getImages(), eq::Channel::getInputFrames(), eq::Channel::getObjectManager(), eq::Channel::getPixelViewport(), eq::Channel::getRange(), eq::Frame::getRange(), eq::Frame::getZoom(), eq::PixelViewport::hasArea(), eq::PixelViewport::intersect(), eq::Zoom::NONE, eq::Channel::resetAssemblyState(), eq::Frame::setPixelViewport(), eq::Frame::setZoom(), eq::Frame::startReadback(), eq::Frame::syncReadback(), and eq::Frame::waitReady().

Here is the call graph for this function:

void eVolve::Channel::frameReadback ( const uint32_t frameID ) [protected, virtual]

Read back the rendered scene.

Called 0 to n times during one frame.

Parameters:

frameID

the per-frame identifier.

See also:: getOutputFrames

Reimplemented from eq::Channel.

Definition at line 331 of file examples/eVolve/channel.cpp.

References eq::Frame::BUFFER_DEPTH, and eq::Channel::getOutputFrames().

Here is the call graph for this function:

void eVolve::Channel::frameViewFinish ( const uint32_t frameID ) [protected, virtual]

Finish updating a destination channel.

Called once on each destination channel before frameFinish, e.g., channels which are defined by a view/segment intersection, updating a part of a display.

This is typically used to do operations on the output channel after it has been fully updated, e.g., to draw a 2D overlay.

Parameters:

frameID

the per-frame identifier.

Reimplemented from eq::Channel.

Definition at line 344 of file examples/eVolve/channel.cpp.

void eVolve::Channel::applyFrustum ( ) const [protected, virtual]

Applies the perspective or orthographic frustum.

Reimplemented from eq::Channel.

Definition at line 166 of file examples/eVolve/channel.cpp.

References eq::Channel::applyOrtho().
