Impressive Real-Time Lighting Tech Used for Sunset Overdrive on Xbox One Shown by Insomniac Games
One of the most impressive elements of Sunset Overdrive is definitely its lighting, that gives the game a very unique look. Insomniac Games developed a new technology named “Light Linked List” or “LLL” for short, which allowed the developer to achieve definitely impressive results.
The technique was showcased during the “Advances in Real-Time Rendering” course at Siggraph 2014 by Senior Engine Programmer Abdul Bezrati, and works by storing “dynamic lights in a linked list accessible per-pixels for all the elements in a game scene.”
Not only it speeds up the rendering of dynamic lights, but it also allows transparent effects and particles to receive lighting and shading.
Below you can see a picture of a scene rendered using traditional deferred lighting compared with and a few using LLL, and a video giving us a glimpse of the lighting effects that can be achieved with Insomniac’s new tech.
