static vtkTypeBool vtkWebApplication::IsTypeOf ( const char * type )

static

virtual vtkTypeBool vtkWebApplication::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

void vtkWebApplication::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

virtual void vtkWebApplication::SetImageEncoding ( int )

virtual

Set the encoding to be used for rendered images.

virtual int vtkWebApplication::GetImageEncoding ( )

virtual

Set the encoding to be used for rendered images.

virtual void vtkWebApplication::SetImageCompression ( int )

virtual

Set the compression to be used for rendered images.

virtual int vtkWebApplication::GetImageCompression ( )

virtual

Set the compression to be used for rendered images.

void vtkWebApplication::SetNumberOfEncoderThreads ( vtkTypeUInt32 )

Set the number of worker threads to use for image encoding.

Calling this method with a number greater than 32 or less than zero will have no effect.

vtkTypeUInt32 vtkWebApplication::GetNumberOfEncoderThreads ( )

Set the number of worker threads to use for image encoding.

Calling this method with a number greater than 32 or less than zero will have no effect.

vtkUnsignedCharArray* vtkWebApplication::StillRender	(	vtkRenderWindow *	view,
		int	quality = `100`
	)

Render a view and obtain the rendered image.

vtkUnsignedCharArray* vtkWebApplication::InteractiveRender	(	vtkRenderWindow *	view,
		int	quality = `50`
	)

Render a view and obtain the rendered image.

const char* vtkWebApplication::StillRenderToString	(	vtkRenderWindow *	view,
		vtkMTimeType	time = `0`,
		int	quality = `100`
	)

Render a view and obtain the rendered image.

bool vtkWebApplication::GetHasImagesBeingProcessed ( vtkRenderWindow * )

StillRenderToString() need not necessary returns the most recently rendered image.

Use this method to get whether there are any pending images being processed concurrently.

bool vtkWebApplication::HandleInteractionEvent	(	vtkRenderWindow *	view,
		vtkWebInteractionEvent *	event
	)

Communicate mouse interaction to a view.

Returns true if the interaction changed the view state, otherwise returns false.

void vtkWebApplication::InvalidateCache ( vtkRenderWindow * view )

Invalidate view cache.

virtual vtkMTimeType vtkWebApplication::GetLastStillRenderToMTime ( )

virtual

Return the MTime of the last array exported by StillRenderToString.

const char* vtkWebApplication::GetWebGLSceneMetaData ( vtkRenderWindow * view )

Return the Meta data description of the input scene in JSON format.

This is using the vtkWebGLExporter to parse the scene. NOTE: This should be called before getting the webGL binary data.

const char* vtkWebApplication::GetWebGLBinaryData	(	vtkRenderWindow *	view,
		const char *	id,
		int	partIndex
	)

Return the binary data given the part index and the webGL object piece id in the scene.

vtkObjectIdMap* vtkWebApplication::GetObjectIdMap ( )

static std::string vtkWebApplication::GetObjectId ( vtkObject * obj )

static

Return a hexadecimal formatted string of the VTK object's memory address, useful for uniquely identifying the object when exporting data.

e.g. 0x8f05a90
