virtual vtkTypeBool vtkPoints::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 vtkObjectBase.

Reimplemented in vtkPointsProjectedHull.

void vtkPoints::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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.

Reimplemented in vtkPointsProjectedHull.

virtual vtkTypeBool vtkPoints::Allocate	(	vtkIdType	sz,
		vtkIdType	ext = `1000`
	)

virtual

Allocate initial memory size.

ext is no longer used.

virtual void vtkPoints::Initialize ( )

virtual

Return object to instantiated state.

Reimplemented in vtkPointsProjectedHull.

virtual void vtkPoints::SetData ( vtkDataArray * )

virtual

Set/Get the underlying data array.

This function must be implemented in a concrete subclass to check for consistency. (The tuple size must match the type of data. For example, 3-tuple data array can be assigned to a vector, normal, or points object, but not a tensor object, which has a tuple dimension of 9. Scalars, on the other hand, can have tuple dimension from 1-4, depending on the type of scalar.)

Make object look empty but do not delete memory.

Reimplemented in vtkPointsProjectedHull.

Definition at line 268 of file vtkPoints.h.

virtual void vtkPoints::DeepCopy ( vtkPoints * ad )

virtual

Different ways to copy data.

Shallow copy does reference count (i.e., assigns pointers and updates reference count); deep copy runs through entire data array assigning values.

virtual void vtkPoints::ShallowCopy ( vtkPoints * ad )

virtual

Different ways to copy data.

Shallow copy does reference count (i.e., assigns pointers and updates reference count); deep copy runs through entire data array assigning values.

unsigned long vtkPoints::GetActualMemorySize ( )

Return the memory in kibibytes (1024 bytes) consumed by this attribute data.

Used to support streaming and reading/writing data. The value returned is guaranteed to be greater than or equal to the memory required to actually represent the data represented by this object. The information returned is valid only after the pipeline has been updated.

vtkIdType vtkPoints::GetNumberOfPoints ( )

inline

Return number of points in array.

Definition at line 132 of file vtkPoints.h.

double* vtkPoints::GetPoint ( vtkIdType id )

inline

Return a pointer to a double point x[3] for a specific id.

WARNING: Just don't use this error-prone method, the returned pointer and its values are only valid as long as another method invocation is not performed. Prefer GetPoint() with the return value in argument.

Definition at line 140 of file vtkPoints.h.

void vtkPoints::GetPoint	(	vtkIdType	id,
		double	x[3]
	)

inline

Copy point components into user provided array v[3] for specified id.

inline

Insert point into object.

No range checking performed (fast!). Make sure you use SetNumberOfPoints() to allocate memory prior to using SetPoint(). You should call Modified() finally after changing points using this method as it will not do it itself.
