Constructor & Destructor Documentation

WHeadSurfaceCallback()

WHeadSurfaceCallback::WHeadSurfaceCallback	(	const std::vector< std::size_t > &	channelIDs,
		WPropDouble	colorSensitivity,
		std::shared_ptr< WFlag< std::shared_ptr< WEEGEvent > > >	event
	)

Constructor.

Parameters

channelIDs	the mapping from vertex indices to channel IDs
colorSensitivity	The sensitivity of the color map as property. The color map ranges from -colorSensitivity to +colorSensitivity in microvolt.
event	event marking a special time position as WFlag

update()

void WHeadSurfaceCallback::update ( osg::NodeVisitor *  , osg::Drawable *  drawable  )

virtual

Callback method called by the NodeVisitor.

Changes the color of the head surface according to the event.

Parameters

drawable

The drawable this callback is connected to. Should be a Geometry with a 1D texture.
