Detailed Description

helper object to manage setting and generating contour values

Date

Revision
1.22

vtkContourValues is a general class to manage the creation, generation, and retrieval of contour values. This class serves as a helper class for contouring classes, or those classes operating on lists of contour values.

Member Function Documentation

vtkContourValues* vtkContourValues::New  )  [static]
 

Construct object with a single contour value at 0.0.

Reimplemented from vtkObject.

virtual const char* vtkContourValues::GetClassName  )  [virtual]
 

Reimplemented from vtkObject.

int vtkContourValues::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkContourValues::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

vtkContourValues* vtkContourValues::SafeDownCast vtkObject o  )  [static]
 

Reimplemented from vtkObject.

void vtkContourValues::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 vtkObject.

void vtkContourValues::SetValue int  i,
float  value
 

Set the ith contour value.

Referenced by vtkContourGrid::SetValue(), vtkContourFilter::SetValue(), and vtkBandedPolyDataContourFilter::SetValue().

float vtkContourValues::GetValue int  i  ) 
 

Get the ith contour value. The return value will be clamped if the index i is out of range.

Referenced by vtkContourGrid::GetValue(), vtkContourFilter::GetValue(), and vtkBandedPolyDataContourFilter::GetValue().

float* vtkContourValues::GetValues  ) 
 

Return a pointer to a list of contour values. The contents of the list will be garbage if the number of contours <= 0.

Referenced by vtkContourGrid::GetValues(), vtkContourFilter::GetValues(), and vtkBandedPolyDataContourFilter::GetValues().

void vtkContourValues::GetValues float *  contourValues  ) 
 

Fill a supplied list with contour values. Make sure you've allocated memory of size GetNumberOfContours().

void vtkContourValues::SetNumberOfContours const int  number  ) 
 

Set the number of contours to place into the list. You only really need to use this method to reduce list size. The method SetValue() will automatically increase list size as needed.

Referenced by vtkContourGrid::SetNumberOfContours(), vtkContourFilter::SetNumberOfContours(), and vtkBandedPolyDataContourFilter::SetNumberOfContours().

int vtkContourValues::GetNumberOfContours  ) 
 

Return the number of contours in the

Referenced by vtkContourGrid::GetNumberOfContours(), vtkContourFilter::GetNumberOfContours(), and vtkBandedPolyDataContourFilter::GetNumberOfContours().

void vtkContourValues::GenerateValues int  numContours,
float  range[2]
 

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

Referenced by vtkContourGrid::GenerateValues(), vtkContourFilter::GenerateValues(), and vtkBandedPolyDataContourFilter::GenerateValues().

void vtkContourValues::GenerateValues int  numContours,
float  rangeStart,
float  rangeEnd
 

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.
