Revision:
1.53

vtkPoints represents 3D points. The data model for vtkPoints is an array of vx-vy-vz triplets accessible by (point or cell) id.

Examples:

Member Function Documentation

vtkPoints* vtkPoints::New (  int    dataType )  [static]
 

vtkPoints* vtkPoints::New (    )  [static]
 

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

Reimplemented from vtkObject.

Reimplemented in vtkFloatPoints.

virtual const char* vtkPoints::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 vtkAttributeData.

int vtkPoints::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 vtkAttributeData.

virtual int vtkPoints::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 vtkAttributeData.

vtkPoints* vtkPoints::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 vtkAttributeData.

void vtkPoints::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 vtkAttributeData.

vtkAttributeData* vtkPoints::MakeObject (    )  [virtual]
 

Create a copy of this object.

Reimplemented from vtkAttributeData.

int vtkPoints::GetNumberOfPoints (    )  [inline]
 

Return number of points in array.

Definition at line 76 of file vtkPoints.h.

Referenced by vtkPointSet::GetNumberOfPoints().

float* vtkPoints::GetPoint (  int    id )  [inline]
 

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

Definition at line 79 of file vtkPoints.h.

void vtkPoints::GetPoint (  int    id,
float    x[3]
)  [inline]
 

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

Definition at line 82 of file vtkPoints.h.

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

Definition at line 83 of file vtkPoints.h.

void vtkPoints::SetPoint (  int    id,
const float    x[3]
)  [inline]
 

Insert point into object. No range checking performed (fast!). Make sure you use SetNumberOfPoints() to allocate memory prior to using SetPoint().

Definition at line 88 of file vtkPoints.h.

void vtkPoints::SetPoint (  int    id,
const double    x[3]
)  [inline]
 

Definition at line 89 of file vtkPoints.h.

void vtkPoints::SetPoint (  int    id,
double    x,
double    y,
double    z
)  [inline]
 

Definition at line 145 of file vtkPoints.h.

void vtkPoints::InsertPoint (  int    id,
const float    x[3]
)  [inline]
 

Insert point into object. Range checking performed and memory allocated as necessary.

Definition at line 94 of file vtkPoints.h.

void vtkPoints::InsertPoint (  int    id,
const double    x[3]
)  [inline]
 

Definition at line 95 of file vtkPoints.h.

void vtkPoints::InsertPoint (  int    id,
double    x,
double    y,
double    z
)  [inline]
 

Definition at line 154 of file vtkPoints.h.

int vtkPoints::InsertNextPoint (  const float    x[3] )  [inline]
 

Insert point into next available slot. Returns id of slot.

Definition at line 99 of file vtkPoints.h.

int vtkPoints::InsertNextPoint (  const double    x[3] )  [inline]
 

Definition at line 101 of file vtkPoints.h.

int vtkPoints::InsertNextPoint (  double    x,
double    y,
double    z
)  [inline]
 

Definition at line 164 of file vtkPoints.h.

void vtkPoints::SetNumberOfPoints (  int    number )  [inline]
 

Specify the number of points for this object to hold. Does an allocation as well as setting the MaxId ivar. Used in conjunction with SetPoint() method for fast insertion.

Definition at line 139 of file vtkPoints.h.

void vtkPoints::GetPoints (  vtkIdList *    ptId,
vtkPoints *    fp
) 
 

Given a list of pt ids, return an array of points.

virtual void vtkPoints::ComputeBounds (    )  [virtual]
 

Determine (xmin,xmax, ymin,ymax, zmin,zmax) bounds of points.

float* vtkPoints::GetBounds (    ) 
 

Return the bounds of the points.

void vtkPoints::GetBounds (  float    bounds[6] ) 
 

Return the bounds of the points.

void vtkPoints::GetPoints (  vtkIdList &    ptId,
vtkPoints &    fp
)  [inline]
 

For legacy compatibility. Do not use.
