Call of Duty: Ghosts’ New Engine Explained
Infinity Ward has released a new video showcasing the game’s powerful engine technology, with features including Sub D and Displacement Mapping. According to its creators, the engine creates a huge leap in visual fidelity and graphical immersion.
To highlight the graphical leap forward, Infinity Ward has decided to showcase a new tessellation method called Displacement Mapping, which essentially allows the engine to create high-res geometry in real-time on trained surfaces that were in the past very flat. With Displacement Maps on, real geometry forms out of flat surfaces based on the textures they pull from. To better illustrate how the whole thing works, the studio showcases the feature in real time through the dev tools.
Sub-D, or “subdivide” allows the developers to depict curved surfaces, which is used to depict perfectly round scopes, for example. That too is showcased in the video.
Other elements that have made it into the engine include HDR, Volumetric Lighting, and real-time ADSR.
