Detailed Description

GPU implementation of a Line Integral Convolution, a technique for imaging vector fields.

The input on port 0 is an 2D vtkStructuredGrid. It needs a vector field on point data. Port 1 is a special port for customized noise input. It is an optional port. If not present, noise is generated by the filter. Even if none-power-of-two texture are supported, giving a power-of-two image may result in faster execution on the GPU.

Please refer to Forssell, L. K., “Visualizing flow over curvilinear grid surfaces using line integral convolution”, Visualization 94 Conference Proceedings, pages 240-247, IEEE Computer Society, 1994 for details of the algorithm.

Member Function Documentation

static vtkStructuredGridLIC2D* vtkStructuredGridLIC2D::New ( )
static
virtual const char* vtkStructuredGridLIC2D::GetClassName ( )
virtual

Reimplemented from vtkStructuredGridAlgorithm.

static int vtkStructuredGridLIC2D::IsTypeOf ( const char *  type)
static
virtual int vtkStructuredGridLIC2D::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 vtkStructuredGridAlgorithm.

static vtkStructuredGridLIC2D* vtkStructuredGridLIC2D::SafeDownCast ( vtkObject o)
static
void vtkStructuredGridLIC2D::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 vtkStructuredGridAlgorithm.

int vtkStructuredGridLIC2D::SetContext ( vtkRenderWindow context)

Get/Set the context. Context must be a vtkOpenGLRenderWindow. This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions. Return 0 upon failure and 1 upon success.

vtkRenderWindow* vtkStructuredGridLIC2D::GetContext ( )

Get/Set the context. Context must be a vtkOpenGLRenderWindow. This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions. Return 0 upon failure and 1 upon success.

virtual void vtkStructuredGridLIC2D::SetSteps ( int  )
virtual

Number of steps. Initial value is 1. class invariant: Steps>0. In term of visual quality, the greater the better.

virtual int vtkStructuredGridLIC2D::GetSteps ( )
virtual

Number of steps. Initial value is 1. class invariant: Steps>0. In term of visual quality, the greater the better.

virtual void vtkStructuredGridLIC2D::SetStepSize ( double  )
virtual

Step size. WE ARE NOT SURE YET about the space where we define the step. If the image data has different spacing in each dimension, it is an issue. Initial value is 1.0. class invariant: StepSize>0.0. In term of visual quality, the smaller the better. The type for the interface is double as VTK interface is double but GPU only supports float. This value will be converted to float in the execution of the algorithm.

virtual double vtkStructuredGridLIC2D::GetStepSize ( )
virtual

Step size. WE ARE NOT SURE YET about the space where we define the step. If the image data has different spacing in each dimension, it is an issue. Initial value is 1.0. class invariant: StepSize>0.0. In term of visual quality, the smaller the better. The type for the interface is double as VTK interface is double but GPU only supports float. This value will be converted to float in the execution of the algorithm.

virtual void vtkStructuredGridLIC2D::SetMagnification ( int  )
virtual

The the magnification factor. Default is 1

virtual int vtkStructuredGridLIC2D::GetMagnification ( )
virtual

The the magnification factor. Default is 1

virtual int vtkStructuredGridLIC2D::GetOpenGLExtensionsSupported ( )
virtual

Check if the required OpenGL extensions / GPU are supported.

int vtkStructuredGridLIC2D::GetFBOSuccess ( )
inline

Check if FBO is started properly.

Check if LIC runs properly.

virtual int vtkStructuredGridLIC2D::FillInputPortInformation ( int  port,
vtkInformation info 
)
protectedvirtual

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle. Redefined from the superclass.

Reimplemented from vtkStructuredGridAlgorithm.

virtual int vtkStructuredGridLIC2D::FillOutputPortInformation ( int  port,
vtkInformation info 
)
protectedvirtual

Fill the output port information objects for this algorithm. This is invoked by the first call to GetOutputPortInformation for each port so subclasses can specify what they can handle. Redefined from the superclass.

Reimplemented from vtkStructuredGridAlgorithm.
