Boots on the Ground: The Terrain of Call of Duty

J.T. Hooker

Over the last couple projects Treyarch developed a new terrain system that's been seen in Black Ops 4, Warzone, and Black Ops Cold War. Part of it is a uniquely powerful set of tools for editing this terrain and developing biomes procedurally for it, where editing features are implemented on the GPU for real-time iteration. This talk goes into details on Black Ops Cold War graphical terrain features that take advantage of virtual texturing to implement seamless blending of artistic elements, and the unique implementation details that allowed us to push as much visual quality as possible in this system while staying in the memory and performance budgets of a 60 fps game.
