a placer that constrains a handle to a finite plane
Converts 2D display positions to world positions such that they lie on an ImageActor.
int ComputeWorldPosition(vtkRenderer *ren, double displayPos[2], double worldPos[3], double worldOrient[9])
Given and renderer and a display position in pixels, find a world position and orientation.
int UpdateWorldPosition(vtkRenderer *ren, double worldPos[3], double worldOrient[9])
Update the world position and orientation according the the current constraints of the placer.
static vtkImageActorPointPlacer * New()
Instantiate this class.
virtual void SetWorldTolerance(double s)
Set the world tolerance.
void SetImageActor(vtkImageActor *)
Set / get the reference vtkImageActor used to place the points.
int ComputeWorldPosition(vtkRenderer *ren, double displayPos[2], double refWorldPos[2], double worldPos[3], double worldOrient[9])
This method is identical to the one above since the reference position is ignored by the bounded plan...
int ValidateWorldPosition(double worldPos[3], double worldOrient[9])
This method is identical to the one above since the bounded plane point placer ignores orientation.
void PrintSelf(ostream &os, vtkIndent indent)
Methods invoked by print to print information about the object including superclasses.
vtkBoundedPlanePointPlacer * Placer
int ValidateWorldPosition(double worldPos[3])
This method validates a world position by checking to see if the world position is valid according to...
int UpdateInternalState()
A method for configuring the internal placer according to the constraints of the image actor.
