bool eVolve::Channel::configInit

(

const eq::uint128_t &

initID

)

[protected, virtual]

Initialize this channel.

Parameters:

initID

the init identifier.

Version:

Here is the call graph for this function:

void eVolve::Channel::frameAssemble

(

const eq::uint128_t &

frameID

)

[protected, virtual]

Assemble all input frames.

Called 0 to n times during one frame.

Parameters:

frameID

the per-frame identifier.

See also:

getInputFrames()

Version:

1.0

Reimplemented from eq::Channel.

Definition at line 252 of file eVolve/channel.cpp.

void eVolve::Channel::frameClear

(

const eq::uint128_t &

frameID

)

[protected, virtual]

Clear the frame buffer.

Called 0 to n times during one frame.

Parameters:

frameID

the per-frame identifier.

Version:

1.0

Reimplemented from eq::Channel.

Definition at line 89 of file eVolve/channel.cpp.

Referenced by osgScaleViewer::Channel::Channel().

Here is the caller graph for this function:

void eVolve::Channel::frameDraw

(

const eq::uint128_t &

frameID

)

[protected, virtual]

Draw the scene.

Called 0 to n times during one frame.

Parameters:

frameID

the per-frame identifier.

Version:

Here is the caller graph for this function:

void eVolve::Channel::frameReadback

(

const eq::uint128_t &

frameID

)

[protected, virtual]

Read back the rendered frame buffer into all output frames.

Called 0 to n times during one frame.

Parameters:

frameID

the per-frame identifier.

See also:

getOutputFrames()

Version:

1.0

Reimplemented from eq::Channel.

Definition at line 337 of file eVolve/channel.cpp.

References eq::Frame::BUFFER_COLOR, eq::Frame::BUFFER_DEPTH, eq::Frame::disableBuffer(), and eq::Frame::setQuality().

Here is the call graph for this function:

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

Parameters:

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

See also:

Config::startFrame()

Version:

1.0

Reimplemented from eq::Channel.

Definition at line 83 of file eVolve/channel.cpp.

References eq::fabric::Range::ALL, eq::Channel::applyBuffer(), eq::Channel::applyViewport(), and eq::fabric::Channel< Window, Channel >::getRange().

Here is the call graph for this function:

void eVolve::Channel::frameViewFinish

(

const eq::uint128_t &

frameID

)

[protected, virtual]

Finish updating a destination channel.

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

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.

Version:

1.0

Reimplemented from eq::Channel.

Definition at line 353 of file eVolve/channel.cpp.

References eq::Channel::applyScreenFrustum(), eq::util::Texture::bind(), eq::util::Texture::getHeight(), eq::util::Texture::getTarget(), eq::util::Texture::getWidth(), and eq::fabric::Channel< Window, Channel >::getWindow().

Here is the call graph for this function:

bool eVolve::Channel::useOrtho

(

)

const [protected, virtual]

Select perspective or orthographic rendering.

Influences the behaviour of getFrustum, getHeadTransform and the corresponding apply methods in eq::Channel. Intended to be overwritten by the implementation to select orthographic rendering.

Version:

1.0

Reimplemented from eq::fabric::Channel< Window, Channel >.

Definition at line 172 of file eVolve/channel.cpp.
