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