Deferred Neighboring Radiance Transfer is an approximated Global Illumination technique developed for use in videogame applications. Global Illumination models simulate how light propagates within a scene taking into account both direct and indirect light. The inclusion of indirect light enriches the scene, giving it a photo-realistic look. Global Illumination methods are too slow for use in real-time applications. Approximated techniques like DNRT are, therefore, necessary. DNRT modifies pre-existing light solutions for static environments enhancing them with reflections and occlusions from dynamic objects. This is done combining two core ideas: light redistribution and precomputation. The result is an efficient screen-space technique that can be used on any scene with only a minor impact on performance.
