a vtkProp3D that always faces the camera
static vtkProp3DFollower * New()
Creates a follower with no camera set.
int RenderTranslucentPolygonalGeometry(vtkViewport *viewport) override
This causes the actor to be rendered.
int RenderVolumetricGeometry(vtkViewport *viewport) override
This causes the actor to be rendered.
void ReleaseGraphicsResources(vtkWindow *) override
Release any graphics resources associated with this vtkProp3DFollower.
void InitPathTraversal() override
Overload vtkProp's method for setting up assembly paths.
int RenderOpaqueGeometry(vtkViewport *viewport) override
This causes the actor to be rendered.
void ComputeMatrix() override

vtkAssemblyPath * GetNextPath() override
Overload vtkProp's method for setting up assembly paths.
~vtkProp3DFollower() override
virtual vtkProp3D * GetProp3D()
Set/Get the vtkProp3D to control (i.e., face the camera).
virtual void SetProp3D(vtkProp3D *prop)
Set/Get the vtkProp3D to control (i.e., face the camera).
double * GetBounds() override
