Cross-Platform Mobile and PC Rendering in 'Earth: Revival'

Chao Wang  (Game Engine Technical Director, Nuverse, JNG Studio)

Location: Room 215, South Hall

Date: Wednesday, March 22

Time: 3:30 pm - 4:30 pm

Pass Type: All Access Pass, Core Pass

Topic: Programming

Format: Lecture

Vault Recording: Video

Audience Level: All

Earth: Revival’ delivers a high-quality open-world game on mobile devices and PCs using a unified, highly scalable cross-platform renderer. The custom Unity-based engine utilizes a hybrid occlusion culling method, a new multi-threaded rendering architecture, a tile-based deferred renderer, and a render graph dedicated to cross-platform optimizations.

In this session, Chao Wang, Game Engine Technical Director at Nuverse, will discuss engine and render pipeline optimizations for multiple generations of mobile and PC devices. He will present techniques for "write once, run anywhere" cross-platform shaders and render passes, and show examples of novel rendering features.


Attendees will learn to customize a renderer for massive open worlds to leverage mobile hardware capacity while being scalable to PCs. Chao will show their implementation within a custom Unity engine, but the techniques presented are applicable to other engines or middleware. Attendees will be inspired by ideas for improving existing techniques and developing new methods to bring next-gen image quality to cross-platform games.​

Intended Audience

This is for mobile and cross-platform game developers, especially those with rendering engine knowledge. Programmers who plan to make high-quality rendering on mobile SOCs will benefit from this talk.​
