void BALL::VIEW::GLRenderWindow::createTexture	(	const unsigned int	winWidth,
		const unsigned int	winHeight
	)

protected

virtual void BALL::VIEW::GLRenderWindow::customEvent ( QEvent * evt )

protectedvirtual

This function handles custom Qt Events.

The main use of this function is notification of a fresh buffer to display from a separate renderer thread.

void BALL::VIEW::GLRenderWindow::deleteTexture ( )

protected

bool BALL::VIEW::GLRenderWindow::errorInGL ( GLenum & error )

protected

float BALL::VIEW::GLRenderWindow::getDownsamplingFactor ( ) const

inline

Get the window's downsampling factor.

Definition at line 79 of file glRenderWindow.h.

String BALL::VIEW::GLRenderWindow::getGLErrorString ( GLenum error )

protected

void BALL::VIEW::GLRenderWindow::ignoreEvents ( bool ignore )

inline

Force the window to ignore paint events.

Definition at line 66 of file glRenderWindow.h.

virtual bool BALL::VIEW::GLRenderWindow::init ( )

virtual

Initialization routine.

Reimplemented from BALL::VIEW::TRenderWindow< taPixelDatatype >.

void BALL::VIEW::GLRenderWindow::lockGLContext ( )

Lock the context for the current thread and make it active.

void BALL::VIEW::GLRenderWindow::paintEvent ( QPaintEvent * e )

protected

virtual void BALL::VIEW::GLRenderWindow::refresh ( )

virtual

Request that the image is actually displayed on the screen or other device the window encapsulated. You should implement this method in subclass. This is different from RenderTarget releaseBuffer. ReleaseBuffer only informs the window that a buffer is ready, but does not imply the buffer is actually displayed somewhere. This is done by refresh. On the other hand, refresh called inbetween getBuffer and releaseBuffer has no effect.

Reimplemented from BALL::VIEW::TRenderWindow< taPixelDatatype >.

virtual void BALL::VIEW::GLRenderWindow::renderText	(	int	x,
		int	y,
		const String &	text,
		const ColorRGBA &	color,

virtual void BALL::VIEW::GLRenderWindow::renderText	(	float	x,
		float	y,

		Size	size = `16`
	)

virtual

virtual bool BALL::VIEW::GLRenderWindow::resize	(	const unsigned int	width,
		const unsigned int	height
	)

virtual

Request new window size. Returns false if such a size cannot be supplied This call must be made before the window buffer is handed out to be rendered. This precondition is being checked automatically, see getBuffer

Reimplemented from BALL::VIEW::TRenderWindow< taPixelDatatype >.

void BALL::VIEW::GLRenderWindow::setDownsamplingFactor ( float dsfactor )

inline

Set the window's downsampling factor. This is a speed up factor.

Definition at line 69 of file glRenderWindow.h.

void BALL::VIEW::GLRenderWindow::setStereoDelta ( float delta )

inline

Set the stereo delta for raytracing in pixels.

Definition at line 73 of file glRenderWindow.h.

void BALL::VIEW::GLRenderWindow::setupStereo	(	float	,
		float
	)

virtual

Sets this render target as a part of a stereo setup.

eye_separation denotes the distance along the right vector used by this "eye".

Reimplemented from BALL::VIEW::RenderTarget.

void BALL::VIEW::GLRenderWindow::unlockGLContext ( )

Unlock the context for the current thread and make it active.
