Summary
🤩
Rockstar🎓
Top SchoolJosh Lawrence is a Senior Software Engineer with a decade of experience specializing in real-time and offline rendering, physically based path tracing, and high-performance graphics systems. He has shipped engine and tooling work for AAA titles at High Moon Studios and now develops path-tracing features for Octane Render at OTOY, building on prior C++ optimizations and out-of-core streaming work at Cesium. His open-source contributions to prominent projects like Cesium and loaders.gl demonstrate a practical focus on 3D-tiles, screen-space error traversal, culling, and browser-compatible, performant rendering for large-scale visualizations. With an MSE in Computer Graphics and a background in chip timing and tooling from AMD, he uniquely bridges low-level performance engineering and advanced rendering research. Colleagues rely on him for tackling complex problems from BVH and spatial structures to VR/volume effects and novel shadowing/ambient techniques.
