vtkRenderer
vtkRenderer is a class in the Visualization Toolkit (VTK) that is responsible for rendering a scene. It takes actors, which represent objects in the scene, and maps them into a render window. A renderer is typically associated with a vtkRenderWindow, and can contain multiple vtkActor objects. Each actor has a position, orientation, and scale, and is represented by one or more vtkProp3D objects.
The vtkRenderer manages the camera and lights in the scene. The camera defines the viewpoint from which
Key responsibilities of the vtkRenderer include:
* Maintaining a list of actors to be rendered.
* Managing the active camera and lights for the scene.
* Performing the rendering process, transforming 3D geometry into 2D pixels.
* Handling clipping and culling to optimize rendering performance.
Users can interact with the vtkRenderer by adding or removing actors, setting the camera and lights, and
