Why We Need DDGI

Of all the things that make a 3D game immersive, global illumination effects (including reflections, refractions, and shadows) are undoubtedly the jewel in the crown. Simply put, bad lighting can ruin an otherwise great game experience.

A technique for creating real-life lighting is known as dynamic diffuse global illumination (DDGI for short). This technique delivers real-time rendering for games, decorating game scenes with delicate and appealing visuals. In other words, DDGI brings out every color in a scene by dynamically changing the lighting, realizing the distinct relationship between objects and scene temperature, as well as enriching levels of representation for information in a scene.
