Detailed Description

helper object to manage the visibility of points and cells

vtkStructuredVisibilityConstraint is a general class to manage a list of points/cell marked as invalid or invisible. Currently, it does this by maintaining an unsigned char array associated with points/cells. To conserve memory, this array is allocated only when it is needed (when Blank() is called the first time). Make sure to call Initialize() with the right dimensions before calling any methods that set/get visibility.

Member Function Documentation

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

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

Reimplemented from vtkObject.

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

Reimplemented from vtkObject.

static int vtkStructuredVisibilityConstraint::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 vtkObject.

virtual int vtkStructuredVisibilityConstraint::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 vtkObject.

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

Reimplemented from vtkObject.

void vtkStructuredVisibilityConstraint::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.

unsigned char vtkStructuredVisibilityConstraint::IsVisible ( vtkIdType  id  )  [inline]

Returns 1 is the point/cell is visible, 0 otherwise.

Definition at line 103 of file vtkStructuredVisibilityConstraint.h.

void vtkStructuredVisibilityConstraint::Blank ( vtkIdType  id  )  [inline]

Sets the visibility flag of the given point/cell off. The first time blank is called, a new visibility array is created if it doesn't exist.

Definition at line 111 of file vtkStructuredVisibilityConstraint.h.

void vtkStructuredVisibilityConstraint::UnBlank ( vtkIdType  id  )  [inline]

Sets the visibility flag of the given point/cell on.

Definition at line 128 of file vtkStructuredVisibilityConstraint.h.

virtual int* vtkStructuredVisibilityConstraint::GetDimensions (  )  [virtual]

Get the dimensions used to initialize the object.

virtual void vtkStructuredVisibilityConstraint::GetDimensions ( int  data[3]  )  [virtual]

Get the dimensions used to initialize the object.

void vtkStructuredVisibilityConstraint::Initialize ( int  dims[3]  )  [inline]

Set the dimensions and set the Initialized flag to 1. Once an object is initialized, it's dimensions can not be changed anymore.

Definition at line 139 of file vtkStructuredVisibilityConstraint.h.

void vtkStructuredVisibilityConstraint::SetVisibilityById ( vtkUnsignedCharArray vis  ) 

Set/Get the array used to store the visibility flags.

virtual vtkUnsignedCharArray* vtkStructuredVisibilityConstraint::GetVisibilityById (  )  [virtual]

Set/Get the array used to store the visibility flags.

void vtkStructuredVisibilityConstraint::ShallowCopy ( vtkStructuredVisibilityConstraint src  ) 

Copies the dimensions, the visibility array pointer and the initialized flag.

void vtkStructuredVisibilityConstraint::DeepCopy ( vtkStructuredVisibilityConstraint src  ) 

Copies the dimensions, the visibility array and the initialized flag.

unsigned char vtkStructuredVisibilityConstraint::IsConstrained (  )  [inline]

Returns 0 if there is no visibility array (all cells/points are visible), 0 otherwise.
