Detailed Description

select a cell by shooting a ray into graphics window.

Date:

2000/12/10 20:08:31

Revision:

1.29

vtkCellPicker is used to select a cell by shooting a ray into graphics window and intersecting with actor's defining geometry - specifically its cells. Beside returning coordinates, actor and mapper, vtkCellPicker returns the id of the closest cell within the tolerance along the pick ray, and the dataset that was picked.

Member Function Documentation

vtkCellPicker* vtkCellPicker::New (    )  [static]

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

virtual const char* vtkCellPicker::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 vtkPicker.

int vtkCellPicker::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 vtkPicker.

virtual int vtkCellPicker::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 vtkPicker.

vtkCellPicker* vtkCellPicker::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 vtkPicker.

void vtkCellPicker::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 vtkPicker.

virtual int vtkCellPicker::GetCellId (    )  [virtual]

Get the id of the picked cell. If CellId = -1, nothing was picked.

virtual int vtkCellPicker::GetSubId (    )  [virtual]

Get the subId of the picked cell. If SubId = -1, nothing was picked.

virtual float* vtkCellPicker::GetPCoords (    )  [virtual]

Get the parametric coordinates of the picked cell. Only valid if pick was made.

virtual void vtkCellPicker::GetPCoords (  float    data[3] )  [virtual]

void vtkCellPicker::operator= (  const vtkCellPicker &    )  [inline, protected]

Definition at line 85 of file vtkCellPicker.h.

virtual float vtkCellPicker::IntersectWithLine (  float    p1[3], float    p2[3], float    tol, vtkAssemblyPath *    path, vtkProp3D *    p, vtkAbstractMapper3D *    m )  [protected, virtual]

Reimplemented from vtkPicker.

void vtkCellPicker::Initialize (    )  [protected, virtual]

Reimplemented from vtkPicker.
