Summary
👤
Senior🎓
Top SchoolSimon Walton is a senior software engineer based in Richmond, CA, with deep expertise in 3D graphics, real-time rendering, and VR systems spanning over fifteen years. He has built rendering pipelines, shaders, and artist-facing tools across games, VFX, and AEC—most recently contributing to Leica Geosystems after driving UE4-based architectural rendering and DWG pipeline work at Modumate. Simon’s C++ and systems background includes ray-tracing middleware, Maya/SketchUp plugins, and low-level stability fixes in Qt-based VR audio and avatar systems, highlighting his knack for plumbing complex build and integration issues. He combines hands-on engineering with production-focused tooling, having moved between startups and larger engineering teams to ship robust interactive systems. His work often bridges artist workflows and engine-level performance, making him as comfortable iterating on shaders as refactoring core audio-mixer code. Trained at UCL and UCLA, he pairs strong academic foundations with practical delivery across graphics-heavy domains.

Contributions summary:Simon primarily focused on refactoring and improving the audio-mixing codebase, specifically addressing compile-time dependencies and MOC issues within the Qt framework. Their work involved adding include statements for forward declarations and reordering them to mitigate build problems. Additionally, the user contributed to the implementation of the avatar system, by incorporating data transfer and control. The primary focus of the work was on improving the stability and robustness of the core audio-mixer and avatar-system components in the next-gen VR system.
