represents an object (geometry & properties) in a rendered scene
Definition: vtkActor.h:50
a simple class to control print indentation
Definition: vtkIndent.h:38
an actor that supports multiple levels of detail
Definition: vtkLODActor.h:72
static vtkLODActor * New()
Creates a vtkLODActor with the following defaults: origin(0,0,0) position=(0,0,0) scale=(1,...
virtual void SetMediumResFilter(vtkPolyDataAlgorithm *)
You may plug in your own filters to decimate/subsample the input.
void Render(vtkRenderer *, vtkMapper *) override
This causes the actor to be rendered.
virtual void DeleteOwnLODs()
virtual void UpdateOwnLODs()
void ReleaseGraphicsResources(vtkWindow *) override
Release any graphics resources that are being consumed by this actor.
~vtkLODActor() override
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void ShallowCopy(vtkProp *prop) override
Shallow copy of an LOD actor.
