To create an instance of class vtkFocalPlanePointPlacer, simply invoke its constructor as follows
obj = vtkFocalPlanePointPlacer
obj
is an instance of the vtkFocalPlanePointPlacer class.
string = obj.GetClassName ()
- Standard methods for instances of this class.
int = obj.IsA (string name)
- Standard methods for instances of this class.
vtkFocalPlanePointPlacer = obj.NewInstance ()
- Standard methods for instances of this class.
vtkFocalPlanePointPlacer = obj.SafeDownCast (vtkObject o)
- Standard methods for instances of this class.
int = obj.ComputeWorldPosition (vtkRenderer ren, double displayPos[2], double worldPos[3], double worldOrient[9])
int = obj.ComputeWorldPosition (vtkRenderer ren, double displayPos[2], double refWorldPos[3], double worldPos[3], double worldOrient[9])
- Given a renderer, a display position, and a reference
world position, compute a new world position. The
orientation will be the standard coordinate axes, and the
computed world position will be created by projecting
the display point onto a plane that is parallel to
the focal plane and runs through the reference world
position. This method is typically used to move existing
points.
int = obj.ValidateWorldPosition (double worldPos[3])
- Validate a world position. All world positions
are valid so these methods always return 1.
int = obj.ValidateWorldPosition (double worldPos[3], double worldOrient[9])
- Validate a world position. All world positions
are valid so these methods always return 1.
obj.SetOffset (double )
- Optionally specify a signed offset from the focal plane for the points to
be placed at. If negative, the constraint plane is offset closer to the
camera. If positive, its further away from the camera.
double = obj.GetOffset ()
- Optionally specify a signed offset from the focal plane for the points to
be placed at. If negative, the constraint plane is offset closer to the
camera. If positive, its further away from the camera.
obj.SetPointBounds (double , double , double , double , double , double )
- Optionally Restrict the points to a set of bounds. The placer will
invalidate points outside these bounds.
obj.SetPointBounds (double a[6])
- Optionally Restrict the points to a set of bounds. The placer will
invalidate points outside these bounds.
double = obj. GetPointBounds ()
- Optionally Restrict the points to a set of bounds. The placer will
invalidate points outside these bounds.
