Public Types
enum	FragmentProgram : int { fpPassthrough = 0 , fpSpotlight = 1 }
	Enumeration of available shader inner programs passed to #ShaderProgram::Uniform::uProgram uniform. More...

Public Member Functions
	DemoRenderer (OpenGLWidget *widget, ShaderProgram *sp)
	~DemoRenderer () override
void	start (int msecs)
void	setIndexValue (int index, QVariant value) override
	Sets an arbitrary value on the derived- or subclass.
Public Member Functions inherited from sf::OpenGLRenderer
	OpenGLRenderer (OpenGLWidget *widget, QOpenGLShaderProgram *sp)
	Constructor passing the widget which has the OpenGL context. The owner is the shader program object.
	~OpenGLRenderer () override=default
	Virtual destructor.
bool	setup ()
	Call overridden method generate() after the shader program has been linked.
void	render ()
	Call overridden method render() after the shader program has been linked.
OpenGLWidget *	getWidget () const
	Gets the owning widget which is calling the shots.
QOpenGLShaderProgram *	getShaderProgram () const
	Gets shader program given in the constructor.
virtual void	addRenderObject (OpenGLRenderObject *ro, bool append=true)
	Adds an object to be rendered. The order of addition determines the outcome when transparency is involved. When an object is destroyed, it is removed from the list using the 'destroyed' signal.
Q_SIGNAL void	rendering ()
	Signal emitted at the start of the render() method.

Protected Member Functions
void	generate () override
	Called by setup() and (re-)generates the vertices for the drawn 3D-objects.
void	paint () override
	Called by from the render() method.
void	draw () override
	Called by from the render() method.
void	timerEvent (QTimerEvent *event) override
void	changedProperty () override
	Called by sf::OpenGLWidget when a property has changed.
void	notify (void *)

Properties
QColor	lightColor
float	cutoffAngle

Additional Inherited Members
Static Public Member Functions inherited from sf::OpenGLRenderer
static void	initialize (OpenGLWidget *widget)
	Called by sf::OpenGLWidget::initializeGL to initialize the OpenGL context for derived classes.
Protected Attributes inherited from sf::OpenGLRenderer
OpenGLRenderObject::List	_renderObjects
	Holds the list of objects to render.
const QMatrix4x4 &	_projectionMatrix
	Easy of access reference to the projection matrix from the widget.
const QMatrix4x4 &	_cameraMatrix
	Easy of access reference to the camera matrix from the sf::OpenGLWidget.
const QMatrix4x4 &	_lightPositionMatrix
	Easy of access reference to the light position matrix from the sf::OpenGLWidget.
const QMatrix4x4 &	_lightDirectionMatrix
	Easy of access reference to the light direction matrix from the sf::OpenGLWidget.
const QMatrix4x4 &	_modelMatrix
	Easy of access reference to the model matrix from the sf::OpenGLWidget.
