Detailed Description

compute 1D, 2D, or 3D texture coordinates based on scalar threshold

vtkThresholdTextureCoords is a filter that generates texture coordinates for any input dataset type given a threshold criterion. The criterion can take three forms: 1) greater than a particular value (ThresholdByUpper()); 2) less than a particular value (ThresholdByLower(); or 3) between two values (ThresholdBetween(). If the threshold criterion is satisfied, the "in" texture coordinate will be set (this can be specified by the user). If the threshold criterion is not satisfied the "out" is set.

Warning:: There is a texture map - texThres.vtk - that can be used in conjunction with this filter. This map defines a "transparent" region for texture coordinates 0<=r<0.5, and an opaque full intensity map for texture coordinates 0.5<r<=1.0. There is a small transition region for r=0.5.

Member Function Documentation

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

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

Reimplemented from vtkDataSetAlgorithm.

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

Reimplemented from vtkDataSetAlgorithm.

static int vtkThresholdTextureCoords::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 vtkDataSetAlgorithm.

virtual int vtkThresholdTextureCoords::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 vtkDataSetAlgorithm.

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

Reimplemented from vtkDataSetAlgorithm.

void vtkThresholdTextureCoords::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 vtkDataSetAlgorithm.

void vtkThresholdTextureCoords::ThresholdByLower ( double lower )

Criterion is cells whose scalars are less than lower threshold.

void vtkThresholdTextureCoords::ThresholdByUpper ( double upper )

Criterion is cells whose scalars are less than upper threshold.

void vtkThresholdTextureCoords::ThresholdBetween	(	double	lower,
		double	upper
	)

Criterion is cells whose scalars are between lower and upper thresholds.

virtual double vtkThresholdTextureCoords::GetUpperThreshold ( ) [virtual]

Return the upper and lower thresholds.

virtual double vtkThresholdTextureCoords::GetLowerThreshold ( ) [virtual]

Return the upper and lower thresholds.

virtual void vtkThresholdTextureCoords::SetTextureDimension ( int ) [virtual]

Set the desired dimension of the texture map.

virtual int vtkThresholdTextureCoords::GetTextureDimension ( ) [virtual]

Set the desired dimension of the texture map.

virtual void vtkThresholdTextureCoords::SetInTextureCoord	(	double	,
		double	,
		double
	)			`[virtual]`

Set the texture coordinate value for point satisfying threshold criterion.

virtual void vtkThresholdTextureCoords::SetInTextureCoord ( double [3] ) [virtual]

Set the texture coordinate value for point satisfying threshold criterion.

virtual double* vtkThresholdTextureCoords::GetInTextureCoord ( ) [virtual]

Set the texture coordinate value for point satisfying threshold criterion.

virtual void vtkThresholdTextureCoords::GetInTextureCoord ( double data[3] ) [virtual]

Set the texture coordinate value for point satisfying threshold criterion.

virtual void vtkThresholdTextureCoords::SetOutTextureCoord	(	double	,
		double	,
		double
	)			`[virtual]`

Set the texture coordinate value for point NOT satisfying threshold criterion.

virtual void vtkThresholdTextureCoords::SetOutTextureCoord ( double [3] ) [virtual]

Set the texture coordinate value for point NOT satisfying threshold criterion.

virtual double* vtkThresholdTextureCoords::GetOutTextureCoord ( ) [virtual]

Set the texture coordinate value for point NOT satisfying threshold criterion.

virtual void vtkThresholdTextureCoords::GetOutTextureCoord ( double data[3] ) [virtual]

Set the texture coordinate value for point NOT satisfying threshold criterion.

int vtkThresholdTextureCoords::RequestData	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)			`[protected, virtual]`

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.
