| Description | Electronic Arts Inc. is a leading global interactive entertainment software company. EA delivers games, content and online services for Internet-connected consoles, personal computers, mobile phones and tablets. |
| Responsibilities | Member of the Core Systems Group (Foundation), multi-platform game development engine (Frostbite engine) The mathematical library is the heart of video games and is used by all components of the game (Animation, rendering, physics, camera, etc.). The project consists of restructuring the engine to allow the deprecation of obsolete 3D Math library still supported in the Core Engine System, rewriting some algorithms, convert math type from one Math API to another one and merging several versions (3 versions of the library were used by the distinct groups). This is a high-performance mathematical library that uses advanced template trickery for optimization. Converting, say, the Frostbite animation systems from one Math API to another is non-trivial. This project requires both advanced knowledge of programming, particularly in scientific programming, but a good knowledge of 3D mathematics (linear algebra): vector, quaternion, … Due to the large amount of code to be parsed, refactoring would be impossible with a traditional find-and-replace regexp. Automation was done by using Clang AST (Abstract Syntax Tree) tool (wrapped in python scripts). Refactoring was done in two phases: the first phase consists of running scripts replacing old types with new ones (renames types, function signature …). The second step is the difficult part, what was left out by the script. This task required digging into the code, finding bugs, and fixing them, also failures due to missing dependencies that are generated, validating result make sure nothing was broken and, finally test for different platforms (XBox, PS5, PC, …). Typical workflow ■ run Clang scripts on subsector of code base (analyze code) ■ fix functions call and types make it work in the new environment ■ address issues what was left out by the scripts (manual task … merge, name mangling, …missing dependencies) ■ run unit tests ■ check platforms compile ■ repeat until that area of the codebase is clean ■ code review |
