Summary

Rockstar🎓
Top SchoolJohn Reyna is a graphics-focused software engineer and visual artist with ~3 years of professional experience building rendering systems, VR experiences, and tooling for game and embodied AI research. He combines deep 3D mathematics and shader expertise (C++, HLSL/GLSL, Unity C#) with a strong aesthetic sensibility drawn from drawing, sculpture, photography and interactive installations. At Meta’s Habitat group he improved asset QA and interactive 3D viewers used to test thousands of assets for embodied AI, and he’s contributed UI and text-rendering improvements to the well-known Habitat-Sim simulator. His background spans game studios and studios/tools at Adobe and Turn 10, giving him both real-time rendering and practical pipeline experience across Unreal, Unity, and custom engines. John pairs research-grade math (ray tracing, differential geometry, numerical methods) with hands-on fabrication skills like 3D printing and modeling, enabling hybrid physical–digital projects. He’s based in the Seattle area and brings a curious, design-minded approach that often surfaces in polished visual presentation as much as in performant code.

Contributions summary:John primarily focused on enhancing the user interface and expanding functionality of the Habitat-Sim interactive viewer. They updated settings, imported necessary modules, and implemented the display of text within the application window. Key modifications included changing the in-window text background transparency, improving the rendering of text elements, and adjusting the font and rendering parameters to align with the viewer's visual style. These changes directly contributed to the visual presentation and user experience of the simulator.
