Detailed Description

pick an actor/prop using graphics hardware

vtkPropPicker is used to pick an actor/prop given a selection point (in display coordinates) and a renderer. This class uses graphics hardware/rendering system to pick rapidly (as compared to using ray casting as does vtkCellPicker and vtkPointPicker). This class determines the actor/prop and pick position in world coordinates; point and cell ids are not determined.

Member Function Documentation

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

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

Reimplemented from vtkObject.

static int vtkPropPicker::IsTypeOf ( const char * name ) [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 vtkAbstractPropPicker.

virtual int vtkPropPicker::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 vtkAbstractPropPicker.

static vtkPropPicker* vtkPropPicker::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkAbstractPropPicker.

virtual vtkObjectBase* vtkPropPicker::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkAbstractPropPicker.

vtkPropPicker* vtkPropPicker::NewInstance ( ) const

Reimplemented from vtkAbstractPropPicker.

void vtkPropPicker::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 vtkAbstractPropPicker.

int vtkPropPicker::PickProp	(	double	selectionX,
		double	selectionY,
		vtkRenderer *	renderer
	)

Perform the pick and set the PickedProp ivar. If something is picked, a 1 is returned, otherwise 0 is returned. Use the GetViewProp() method to get the instance of vtkProp that was picked. Props are picked from the renderers list of pickable Props.
