Detailed Description
a subclass of actor that always faces the camera
vtkFollower is a subclass of vtkActor that always follows its specified camera. More specifically it will not change its position or scale, but it will continually update its orientation so that it is right side up and facing the camera. This is typically used for text labels in a scene. All of the adjustments that can be made to an actor also will take effect with a follower. So, if you change the orientation of the follower by 90 degrees, then it will follow the camera, but be off by 90 degrees.

Member Function Documentation
| static int vtkFollower::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 vtkActor.
Reimplemented in vtkAxisFollower.
| virtual int vtkFollower::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.

| void vtkFollower::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 in vtkAxisFollower.
| static vtkFollower* vtkFollower::New | ( | ) | [static] |
Creates a follower with no camera set
Reimplemented from vtkActor.
Reimplemented in vtkAxisFollower.
| virtual void vtkFollower::SetCamera | ( | vtkCamera * | ) | [virtual] |
Set/Get the camera to follow. If this is not set, then the follower won't know who to follow.
| virtual vtkCamera* vtkFollower::GetCamera | ( | ) | [virtual] |
Set/Get the camera to follow. If this is not set, then the follower won't know who to follow.
| virtual int vtkFollower::RenderOpaqueGeometry | ( | vtkViewport * | viewport | ) | [virtual] |
This causes the actor to be rendered. It in turn will render the actor's property, texture map and then mapper. If a property hasn't been assigned, then the actor will create one automatically.

| virtual int vtkFollower::RenderTranslucentPolygonalGeometry | ( | vtkViewport * | viewport | ) | [virtual] |
This causes the actor to be rendered. It in turn will render the actor's property, texture map and then mapper. If a property hasn't been assigned, then the actor will create one automatically.

| virtual void vtkFollower::Render | ( | vtkRenderer * | ren | ) | [virtual] |
This causes the actor to be rendered. It in turn will render the actor's property, texture map and then mapper. If a property hasn't been assigned, then the actor will create one automatically.
Reimplemented in vtkAxisFollower.
| virtual int vtkFollower::HasTranslucentPolygonalGeometry | ( | ) | [virtual] |
Does this prop have some translucent polygonal geometry?
Reimplemented from vtkActor.
| virtual void vtkFollower::ReleaseGraphicsResources | ( | vtkWindow * | ) | [virtual] |
Release any graphics resources associated with this vtkProp3DFollower.
Reimplemented from vtkActor.
| virtual void vtkFollower::ComputeMatrix | ( | ) | [virtual] |
Generate the matrix based on ivars. This method overloads its superclasses ComputeMatrix() method due to the special vtkFollower matrix operations.
Reimplemented from vtkProp3D.
| void vtkFollower::ShallowCopy | ( | vtkProp * | prop | ) | [virtual] |
Shallow copy of a follower. Overloads the virtual vtkProp method.
Reimplemented from vtkActor.
