Detailed Description

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

Date:

2001/10/11 13:37:20

Revision:

1.32

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

vtkThresholdTextureCoords* vtkThresholdTextureCoords::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkDataSetSource.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter.

int vtkThresholdTextureCoords::IsTypeOf (  const char *    type )  [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 vtkDataSetToDataSetFilter.

virtual int vtkThresholdTextureCoords::IsA (  const char *    type )  [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 vtkDataSetToDataSetFilter.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter.

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 vtkSource.

void vtkThresholdTextureCoords::ThresholdByLower (  float    lower )

Criterion is cells whose scalars are less than lower threshold.

void vtkThresholdTextureCoords::ThresholdByUpper (  float    upper )

Criterion is cells whose scalars are less than upper threshold.

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

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

virtual float vtkThresholdTextureCoords::GetUpperThreshold (    )  [virtual]

Return the upper and lower thresholds.

virtual float 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 (  float   , float   , float    )  [virtual]

Set the texture coordinate value for point satisfying threshold criterion.

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

Set the texture coordinate value for point satisfying threshold criterion.

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

Set the texture coordinate value for point satisfying threshold criterion.

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

Set the texture coordinate value for point satisfying threshold criterion.

virtual void vtkThresholdTextureCoords::SetOutTextureCoord (  float   , float   , float    )  [virtual]

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

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

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

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

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

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

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

void vtkThresholdTextureCoords::Execute (    )  [protected, virtual]

This method is the old style execute method Reimplemented from vtkSource.
