AbstractRenderer R6 Class

Base class that defines the rendering interface. All backends (ragg, SVG, grid) must implement these methods. Handles coordinate system setup, camera integration, and mobject dispatch.

Public fields

width

Canvas width in pixels

height

Canvas height in pixels

background_color

Background color

camera

Camera object for coordinate transforms

backend_name

Name of this backend
