Detailed Description

Widget encapsulating the OpenGL context.

Constructor & Destructor Documentation

GLWidget()

GLWidget::GLWidget	(	QWidget *	parent = Q_NULLPTR,
		int	updateRate = 60,
		bool	sampleShading = true,
		int	anisotropy = 1
	)

Constructs a new OpenGL widget.

Parameters

parent	the parent widget.
updateRate	the update rate of the widget.
sampleShading	indicates if sample shading is to be used.
anisotropy	the maximum number of samples used for anisotropic filtering.

Member Function Documentation

frameRate

void GLWidget::frameRate ( int  fps )

signal

Signals the current frames per second periodically.

Parameters

fps	the current frames per second.

initializeGL

void GLWidget::initializeGL ( )

protectedvirtualslot

Initializes everything related to OpenGL.

This function is called after the context has been created, before the first invocation of initializeGL() and resizeGL()

keyPressEvent()

void GLWidget::keyPressEvent ( QKeyEvent *  event )

protected

Handles key presses for toggling track filtering.

Parameters

event

the key event.

mouseMoveEvent()

void GLWidget::mouseMoveEvent ( QMouseEvent *  event )

overrideprotected

Handles mouse movement interaction for camera movement.

Parameters

event

the mouse event

mousePressEvent()

void GLWidget::mousePressEvent ( QMouseEvent *  event )

overrideprotected

Handles mouse click interaction for camera movement.

Parameters

event

the mouse event

paintGL

void GLWidget::paintGL ( )

protectedvirtualslot

Renders the scene.

This function is called whenever the widget needs to be updated (e.g. resizing), as well as at a fixed interval.

resizeGL

void GLWidget::resizeGL ( int  w, int  h  )

protectedvirtualslot

Handles resizing of the widget.

Parameters

w	the new width.
h	the new height.

This function is called whenever the widget is resized (e.g. user input).

setDepthCueing

virtual void GLWidget::setDepthCueing ( int  p_depthCueing )

inlinevirtualslot

sets the depth cueing value

Parameters

p_depthCueing

the value

setHalo

virtual void GLWidget::setHalo ( int  p_halo )

inlinevirtualslot

Sets the halo width value.

Parameters

p_halo

the value

setStripDepth

virtual void GLWidget::setStripDepth ( int  p_stripDepth )

inlinevirtualslot

Sets the strip depth value.

Parameters

p_stripDepth

the value

setThickness

virtual void GLWidget::setThickness ( int  p_thickness )

inlinevirtualslot

Sets the line thickness value.

Parameters

p_thickness

the value

setTrackData()

void GLWidget::setTrackData ( const QVector< Track > &&  tracks )

virtual

Prepares track data for rendering.

Parameters

tracks

the track data.

setWireframe

virtual void GLWidget::setWireframe ( bool  enabled )

inlinevirtualslot

Enables / disables wireframe mode.

Parameters

enabled

true for wireframe rendering, false for solid shading.

updateFrame

void GLWidget::updateFrame ( )

protectedvirtualslot

Updates the scene.

This function is called at a fixed interval, which is determined in the constructor. Here everything related to updating the scene should

wheelEvent()

void GLWidget::wheelEvent ( QWheelEvent *  event )

protected

Handles mouse wheel interaction for camera movement.

Parameters

event

the wheel event.
