Detailed Description

DEPRECATED A vtkPolyDataPainter that colors each polygon with a color coded integer.

DEPRECATED. Refer to vtkHardwareSelectionPolyDataPainter instead. This painter will color each polygon in a color that encodes an integer. Doing so allows us to determine what polygon is behind each pixel on the screen.

Two different modes exist. The first mode colors every polygon the same (SetToColorByConstant). By setting the constant with a processor rank this lets us find out which processor rendered each pixel after parallel depth compositing. Alternatively, by changing the constant in between actors this allows us to differentiate visible actors.

The second mode is to render each polygon in the actor with its own color (SetToColorByIncreasingIdent). Because color depth is limited to 24 bits while visualization data is often larger than 2^24 cells, the index which is increasing is implemented as a 72 bit number. You can customize this mode to color the pixels by three different 24 bit fields of the number. Rendering in three separate passes can then differentiate between 2^72 different cells.

Member Function Documentation

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

Reimplemented from vtkPolyDataPainter.

static int vtkIdentColoredPainter::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataPainter.

virtual int vtkIdentColoredPainter::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 vtkPolyDataPainter.

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

Reimplemented from vtkPolyDataPainter.

virtual void vtkIdentColoredPainter::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 vtkPolyDataPainter.

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

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

Reimplemented from vtkObject.

void vtkIdentColoredPainter::ResetCurrentId ( )

resets the current id to "first".

void vtkIdentColoredPainter::ColorByConstant ( unsigned int constant )

Use to color each cell by processor rank or by actor id.

void vtkIdentColoredPainter::ColorByIncreasingIdent ( unsigned int plane )

Use to color each cell with a different index. plane 0 = bits 23..0 of ident. plane 1 = bits 47..24 of ident. plane 2 = bits 71..48 of ident.

void vtkIdentColoredPainter::ColorByActorId ( vtkProp * ActorId )

Use the actor lookup table to lookup a color to render with.

void vtkIdentColoredPainter::ColorByVertex ( )

Use to color each vertex of each cell by its number.

void vtkIdentColoredPainter::MakeActorLookupTable	(	vtkProp **	Props,
		vtkIdTypeArray *	IdsForProps
	)

Allows you to specify a mapping for selected actor ids.

vtkProp* vtkIdentColoredPainter::GetActorFromId ( vtkIdType id )

Allows you to get the id for selected actor.

virtual void vtkIdentColoredPainter::RenderInternal	(	vtkRenderer *	renderer,
		vtkActor *	actor,
		unsigned long	typeflags,
		bool	forceCompileOnly
	)			`[protected, virtual]`

Performs the actual rendering. Subclasses may override this method. default implementation merely call a Render on the DelegatePainter, if any. When RenderInternal() is called, it is assured that the DelegatePainter is in sync with this painter i.e. UpdateDelegatePainter() has been called.

Reimplemented from vtkPainter.
