Detailed Description

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

Date:

2000/12/10 20:09:01

Revision:

1.17

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

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]

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 vtkAbstractPicker.

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 vtkTypeMacro 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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkAbstractPicker.

vtkWorldPointPicker* vtkWorldPointPicker::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 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 (  float    selectionX, float    selectionY, float    selectionZ, vtkRenderer *    renderer )  [virtual]

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

int vtkWorldPointPicker::Pick (  float    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 76 of file vtkWorldPointPicker.h.

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

Definition at line 83 of file vtkWorldPointPicker.h.
