Detailed Description

find world x,y,z corresponding to display x,y,z

vtkWorldPointPicker is used to find the x,y,z world coordinate of a screen x,y,z. This picker cannot pick actors and/or mappers, it simply determines an x-y-z coordinate in world space. (It will always return a x-y-z, even if the selection point is not over a prop/actor.)

Warning:

The PickMethod() is not invoked, but StartPickMethod() and EndPickMethod() are.

Member Function Documentation

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

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

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

Reimplemented from vtkAbstractPicker.

static int vtkWorldPointPicker::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 vtkAbstractPicker.

virtual int vtkWorldPointPicker::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 vtkAbstractPicker.

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

Reimplemented from vtkAbstractPicker.

void vtkWorldPointPicker::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 vtkAbstractPicker.

int vtkWorldPointPicker::Pick (  double  selectionX, double  selectionY, double  selectionZ, vtkRenderer *  renderer )  [virtual]

Perform the pick. (This method overload's the superclass.) Implements vtkAbstractPicker.

int vtkWorldPointPicker::Pick (  double  selectionPt[3], vtkRenderer *  renderer )  [inline]

provided. Normally the first two values for the selection point are x-y pixel coordinate, and the third value is =0. Return non-zero if something was successfully picked. Reimplemented from vtkAbstractPicker. Definition at line 53 of file vtkWorldPointPicker.h. References vtkAbstractPicker::Pick().
