List of all members.

Public Member Functions

• virtual bool canRender (const Size &Sz, format what=rgb, const type_info &type=typeid(unsigned char)) const

  Check in advance if this renderer is able to provide an image of the specified quality.
  

• virtual int grab (const VRequest &Context, const VSceneLayers &RenderObjects, Grab &, const Size &Sz, const RefPtr< VContext::Addendum > &ContextAddendum=NullPtr()) const =0

  Virtual grab function, it is supposed to call Grab::retrieve();.
  

• virtual int grab (const VRequest &Context, Grab &, const Size &Sz, const RefPtr< VContext::Addendum > &ContextAddendum=NullPtr()) const =0

  Virtual grab function, it is supposed to call Grab::retrieve();.
  

• virtual Size preferredSize () const
• bool ProcessTile (Grab &Grabber, const ImageTile &theImageTile) const

  Call this function to deliver frame data to the Grab object after processing it with the local TileProcessor.
  

• Renderer ()

  Constructor.
  

• int Samples () const

  Current antialiasing sample.
  

• virtual void setCamera (const VCamera &TheCameraSettings)

  An optionally implementable function that sets the camera parameters for the given shot.
  

• virtual bool setupMultiSampling (int samples)

  Setup samples for antialiasing default for virtual function is just assignment implementation in derived class would check for hardware capabilities.
  

• ~Renderer ()

  Destructor.

Detailed Description

Base class for a renderer that is able to provide some pixel data.

an implementation may use OpenGL or any other method to do so.

Member Function Documentation

int Wizt::VFrameBuffer::Renderer::grab	(	const VRequest &	Context,
		const VSceneLayers &	RenderObjects,
		Grab &	,
		const Size &	Sz,
		const RefPtr< VContext::Addendum > &	ContextAddendum = NullPtr()
	)		const [pure virtual]

Virtual grab function, it is supposed to call Grab::retrieve();.

Parameters:

RenderObjects	The objects that should be rendered here.
Context	The VRequest providing the context in which this function is called. It is used to avoid infinite recursions.

Implemented in Wizt::GLRenderer.

		Grab &	,
		const Size &	Sz,
		const RefPtr< VContext::Addendum > &	ContextAddendum = NullPtr()

Virtual grab function, it is supposed to call Grab::retrieve();.

Parameters:

RenderObjects	The objects that should be rendered here.
Context	The VRequest providing the context in which this function is called. It is used to avoid infinite recursions.

Implemented in Wizt::GLRenderer.

void Wizt::VFrameBuffer::Renderer::setCamera

(

const VCamera &

TheCameraSettings

)

[virtual]

An optionally implementable function that sets the camera parameters for the given shot.

This function is called *after* the grab() function, once all the rendering is done, because the camera settings may depend on the viewpoint settings that are determined during rendering.

It is the responsibility of the recording function to determine such camera parameters correctly and call this function. The implementation of a Grabber should not rely on this function to be called at all.
