# Decoupled Simulation and Rendering

Separating world dynamics simulation from visual rendering in a learned world model
Decoupled simulation and rendering is an architectural approach in learned world models where the simulation of world dynamics and the rendering of visual output are handled by separate, independent components rather than a single unified model.

The simulation component maintains and updates the world state in response to actions — tracking discrete game logic, physics, and state transitions. The rendering component takes the current world state as input and produces visual output, generating consistent images from the same underlying state across multiple viewpoints.

This separation allows each component to be optimized independently and scaled according to its own requirements. It also enables manipulation of the underlying world state directly — generating new levels or scenarios — while preserving gameplay dynamics, since rendering derives from state rather than owning it.

The approach mirrors modern game engines where physics simulation and rendering are distinct subsystems, except both are entirely learned from data rather than hard-coded.
