Detailed Description

painter that resolves conicident topology.

Provides the ability to shift the z-buffer to resolve coincident topology. For example, if you'd like to draw a mesh with some edges a different color, and the edges lie on the mesh, this feature can be useful to get nice looking lines.

Constructor & Destructor Documentation

vtkCoincidentTopologyResolutionPainter::vtkCoincidentTopologyResolutionPainter ( )

protected

When set and when RESOLVE_COINCIDENT_TOPOLOGY is set to use polygon offset, solid polygonal faces will be offsetted, otherwise lines/vertices will be offsetted.

Member Function Documentation

static vtkCoincidentTopologyResolutionPainter* vtkCoincidentTopologyResolutionPainter::New ( )

static

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

Reimplemented from vtkObject.

Reimplemented in vtkMesaCoincidentTopologyResolutionPainter, and vtkOpenGLCoincidentTopologyResolutionPainter.

virtual const char* vtkCoincidentTopologyResolutionPainter::GetClassName ( )

virtual

Reimplemented from vtkPolyDataPainter.

Reimplemented in vtkMesaCoincidentTopologyResolutionPainter, and vtkOpenGLCoincidentTopologyResolutionPainter.

static int vtkCoincidentTopologyResolutionPainter::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.

Reimplemented in vtkMesaCoincidentTopologyResolutionPainter, and vtkOpenGLCoincidentTopologyResolutionPainter.

virtual int vtkCoincidentTopologyResolutionPainter::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.

Reimplemented in vtkMesaCoincidentTopologyResolutionPainter, and vtkOpenGLCoincidentTopologyResolutionPainter.

static vtkCoincidentTopologyResolutionPainter* vtkCoincidentTopologyResolutionPainter::SafeDownCast ( vtkObject * o )

static

Reimplemented from vtkPolyDataPainter.

Reimplemented in vtkMesaCoincidentTopologyResolutionPainter, and vtkOpenGLCoincidentTopologyResolutionPainter.

void vtkCoincidentTopologyResolutionPainter::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.

Reimplemented in vtkMesaCoincidentTopologyResolutionPainter, and vtkOpenGLCoincidentTopologyResolutionPainter.

static vtkInformationIntegerKey* vtkCoincidentTopologyResolutionPainter::RESOLVE_COINCIDENT_TOPOLOGY ( )

static

Set/Get a global flag that controls whether coincident topology (e.g., a line on top of a polygon) is shifted to avoid z-buffer resolution (and hence rendering problems). If not off, there are two methods to choose from. PolygonOffset uses graphics systems calls to shift polygons, but does not distinguish vertices and lines from one another. ShiftZBuffer remaps the z-buffer to distinguish vertices, lines, and polygons, but does not always produce acceptable results. If you use the ShiftZBuffer approach, you may also want to set the ResolveCoincidentTopologyZShift value. (Note: not all mappers/graphics systems implement this functionality.)

static vtkInformationDoubleKey* vtkCoincidentTopologyResolutionPainter::Z_SHIFT ( )

static

Used to set the z-shift if ResolveCoincidentTopology is set to ShiftZBuffer.

static vtkInformationDoubleVectorKey* vtkCoincidentTopologyResolutionPainter::POLYGON_OFFSET_PARAMETERS ( )

static

Used to set the polygon offset scale factor and units. Used when ResolveCoincidentTopology is set to PolygonOffset.

static vtkInformationIntegerKey* vtkCoincidentTopologyResolutionPainter::POLYGON_OFFSET_FACES ( )

static

When set and when RESOLVE_COINCIDENT_TOPOLOGY is set to use polygon offset, solid polygonal faces will be offsetted, otherwise lines/vertices will be offsetted.

virtual void vtkCoincidentTopologyResolutionPainter::ProcessInformation ( vtkInformation * )

protectedvirtual

Called before RenderInternal() if the Information has been changed since the last time this method was called.

Reimplemented from vtkPolyDataPainter.
