Detailed Description

painter that performs LIC on the surface of arbitrary geometry.

vtkSurfaceLICPainter painter performs LIC on the surface of arbitrary geometry. Point vectors are used as the vector field for generating the LIC. The implementation is based on "Image Space Based Visualization on Unsteady Flow on Surfaces" by Laramee, Jobard and Hauser appeared in proceedings of IEEE Visualization '03, pages 131-138.

Returns true is the rendering context supports extensions needed by this painter.

Returns true is the rendering context supports extensions needed by this painter.


Member Function Documentation

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

Reimplemented from vtkObject.

static int vtkSurfaceLICPainter::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 vtkPainter.

virtual int vtkSurfaceLICPainter::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.

void vtkSurfaceLICPainter::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 vtkPainter.

Release any graphics resources that are being consumed by this mapper. The parameter window could be used to determine which graphic resources to release. In this case, releases the display lists.

Reimplemented from vtkPainter.

Get the output data object from this painter. Overridden to pass the input points (or cells) vectors as the tcoords to the deletage painters. This is required by the internal GLSL shader programs used for generating LIC.

Reimplemented from vtkPainter.

virtual void vtkSurfaceLICPainter::SetEnable ( int  ) [virtual]

Enable/Disable this painter.

virtual int vtkSurfaceLICPainter::GetEnable ( ) [virtual]

Enable/Disable this painter.

virtual void vtkSurfaceLICPainter::EnableOn ( ) [virtual]

Enable/Disable this painter.

virtual void vtkSurfaceLICPainter::EnableOff ( ) [virtual]

Enable/Disable this painter.

void vtkSurfaceLICPainter::SetInputArrayToProcess ( int  fieldAssociation,
const char *  name 
)

Set the vectors to used for applying LIC. By default point vectors are used. Arguments are same as those passed to vtkAlgorithm::SetInputArrayToProcess except the first 3 arguments i.e. idx, port, connection.

void vtkSurfaceLICPainter::SetInputArrayToProcess ( int  fieldAssociation,
int  fieldAttributeType 
)

Set the vectors to used for applying LIC. By default point vectors are used. Arguments are same as those passed to vtkAlgorithm::SetInputArrayToProcess except the first 3 arguments i.e. idx, port, connection.

virtual void vtkSurfaceLICPainter::SetEnhancedLIC ( int  ) [virtual]

Enable/Disable enhanced LIC that improves image quality by increasing inter-streamline contrast while suppressing artifacts. Enhanced LIC performs two passes of LIC, with a 3x3 Laplacian high-pass filter in between that processes the output of pass #1 LIC and forwards the result as the input 'noise' to pass #2 LIC. This flag is automatically turned off during user interaction.

virtual void vtkSurfaceLICPainter::SetNumberOfSteps ( int  ) [virtual]

Get/Set the number of integration steps in each direction.

virtual void vtkSurfaceLICPainter::SetStepSize ( double  ) [virtual]

Get/Set the step size (in pixels).

Get/Set the step size (in pixels).

virtual void vtkSurfaceLICPainter::SetLICIntensity ( double  ) [virtual]

Control the contribution of the LIC in the final output image. 0.0 produces same result as disabling LIC altogether, while 1.0 implies show LIC result alone.

Check if PrepareForRendering passes.

static bool vtkSurfaceLICPainter::IsSupported ( vtkRenderWindow ) [static]

Returns true is the rendering context supports extensions needed by this painter.

void vtkSurfaceLICPainter::GetBounds ( vtkDataObject data,
double  bounds[6] 
) [protected]

Computes data bounds.

virtual void vtkSurfaceLICPainter::ReportReferences ( vtkGarbageCollector collector) [protected, virtual]

Take part in garbage collection.

Reimplemented from vtkPainter.

virtual void vtkSurfaceLICPainter::PrepareForRendering ( vtkRenderer ,
vtkActor  
) [protected, virtual]

Some subclasses may need to do some preprocessing before the actual rendering can be done eg. build efficient representation for the data etc. This should be done here. This method get called after the ProcessInformation() but before RenderInternal().

Reimplemented from vtkPainter.

virtual void vtkSurfaceLICPainter::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.

Prepares output data. Returns true if vectors are available.

bool vtkSurfaceLICPainter::FixTCoords ( vtkDataSet ds) [protected]

Prepares output data. Returns true if vectors are available.

bool vtkSurfaceLICPainter::CanRenderLIC ( vtkRenderer ,
vtkActor  
) [protected]

Returns true when rendering LIC is possible.
