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.

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.

Reimplemented in vtkVRHardwarePicker.

◆ PickProp() [1/2]

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.

◆ PickProp() [2/2]

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

Perform a pick from the user-provided list of vtkProps and not from the list of vtkProps that the render maintains.

◆ Pick() [1/2]

int vtkPropPicker::Pick ( double  selectionX,
double  selectionY,
double  selectionZ,
vtkRenderer renderer 
)
overridevirtual

override superclasses' Pick() method.

Implements vtkAbstractPicker.

◆ Pick3DPoint()

int vtkPropPicker::Pick3DPoint ( double  selectionPt[3],
vtkRenderer ren 
)
overridevirtual

Perform pick operation with selection point provided.

The selectionPt is in world coordinates. Return non-zero if something was successfully picked.

Reimplemented from vtkAbstractPicker.

◆ PickProp3DPoint() [1/2]

int vtkPropPicker::PickProp3DPoint ( double  pos[3],
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.

◆ PickProp3DPoint() [2/2]

int vtkPropPicker::PickProp3DPoint ( double  pos[3],
vtkRenderer renderer,
vtkPropCollection pickfrom
