Detailed Description

Implements compressed tree based compositing.

vtkCompressCompositer operates in multiple processes. Each compositer has a render window. They use vtkMultiProcessController to communicate the color and depth buffer to process 0's render window. It will not handle transparency. Compositing is run length encoding of background pixels.

Member Function Documentation

static vtkCompressCompositer* vtkCompressCompositer::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkCompositer.

virtual const char* vtkCompressCompositer::GetClassName ( ) [virtual]

Reimplemented from vtkCompositer.

static int vtkCompressCompositer::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkCompositer.

virtual int vtkCompressCompositer::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkCompositer.

static vtkCompressCompositer* vtkCompressCompositer::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkCompositer.

void vtkCompressCompositer::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

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 vtkCompositer.

virtual void vtkCompressCompositer::CompositeBuffer	(	vtkDataArray *	pBuf,
		vtkFloatArray *	zBuf,
		vtkDataArray *	pTmp,
		vtkFloatArray *	zTmp
	)			`[virtual]`

This method gets called on every process. The final image gets put into pBuf and zBuf.

Reimplemented from vtkCompositer.

static void vtkCompressCompositer::Compress	(	vtkFloatArray *	zIn,
		vtkDataArray *	pIn,
		vtkFloatArray *	zOut,
		vtkDataArray *	pOut
	)			`[static]`

I am granting access to these methods and making them static So I can create a TileDisplayCompositer which uses compression.

static void vtkCompressCompositer::Uncompress	(	vtkFloatArray *	zIn,
		vtkDataArray *	pIn,
		vtkFloatArray *	zOut,
		vtkDataArray *	pOut,
		int	finalLength
	)			`[static]`

static void vtkCompressCompositer::CompositeImagePair	(	vtkFloatArray *	localZ,
		vtkDataArray *	localP,
		vtkFloatArray *	remoteZ,
		vtkDataArray *	remoteP,
		vtkFloatArray *	outZ,
		vtkDataArray *	outP
	)			`[static]`
