Inheritance diagram for Painter:

Public Slots
void	paint ()
	Starts rendering and paints the whole picture. More...

Signals
void	initializeDone ()
	This signal is emitted if initialization of all required resources for current scene are initialized. The signal is emitted every time if previous scene was deleted and a new scene was synchronized. More...

Public Member Functions
	Painter (PainterQML *painter, QObject *parent=0)
	Constructor of Painter. More...
virtual	~Painter ()
	Destructor. Will delete all rendering related classes and resources. More...
void	updateEnvMap ()
	Updates environment map using config file. More...
bool	isActive () const
	Checks if Painter is active. Active means the painter is rendering. More...
void	setActive (bool active)
	Sets Active state. If active is true the painter renders the picture. More...
void	clearScene ()
	Clears the scene and removes all not anymore required resources. More...
void	synchronizeScene (Scene *scene)
	Painter copies all needed information of scene into own thread. More...

Protected Member Functions
void	initialize ()
	Initializes all required resources, that are direct members of painter (scene independent resources). This method is executed within first paint. More...

Detailed Description

The Painter class Includes the rendering process, thus creating the whole picture. The Painter will be used by QML within rendering thread.

Constructor & Destructor Documentation

Painter::Painter ( PainterQML *  painter, QObject *  parent = 0  )

explicit

Constructor of Painter.

Parameters

painter	Corresponding QML-Painter. Will be informed about finished rendering.
parent	QObject-parent

Painter::~Painter ( )

virtual

Destructor. Will delete all rendering related classes and resources.

Member Function Documentation

void Painter::clearScene

(

)

Clears the scene and removes all not anymore required resources.

void Painter::handleInitializeDone ( )

protectedslot

void Painter::initialize ( )

protected

Initializes all required resources, that are direct members of painter (scene independent resources). This method is executed within first paint.

void Painter::initializeDone ( )

signal

This signal is emitted if initialization of all required resources for current scene are initialized. The signal is emitted every time if previous scene was deleted and a new scene was synchronized.

void Painter::initializeFBOs ( )

protected

void Painter::initializeShaderPrograms ( )

protected

bool Painter::isActive

(

)

const

Checks if Painter is active. Active means the painter is rendering.

Returns

Active state of painter.

void Painter::paint ( )

slot

Starts rendering and paints the whole picture.

void Painter::renderLightRays ( const Camera &  camera )

protected

void Painter::renderScene ( const Camera &  camera )

protected

void Painter::setActive

(

bool

active

)

Sets Active state. If active is true the painter renders the picture.

Parameters

active

void Painter::synchronizeScene

(

Scene *

scene

)

Painter copies all needed information of scene into own thread.

Parameters

scene

The scene that should be synchronized. If nullptr is passed it is like clearScene()

void Painter::updateEnvMap

(

)

Updates environment map using config file.
