A real-time rendering engine generates images from 3D scene descriptions fast enough to sustain interactive frame rates, typically 30 to 120+ frames per second. It coordinates GPU rasterisation or ray tracing, shading, lighting, and post-processing within a fixed per-frame time budget. It is the visual core of game engines, virtual production, and immersive metaverse experiences.

- Modern engines combine deferred or forward rendering, physically based shading, and increasingly hardware ray tracing with denoising. Maintaining frame-rate stability demands level-of-detail, culling, and GPU-driven pipelines. In virtual production, the engine drives LED walls in sync with camera tracking for real-time, photoreal backgrounds.
