Led Tilt Five's Unity SDK team, creating a C#/C++ plugin that lets developers create multiplayer tabletop augmented reality applications for Tilt Five's AR glasses and 6DOF motion tracking wand controller. Our industry-first local multiplayer AR solution supports up to 4 users per host PC, all sharing the same virtual space.The Tilt Five Unity SDK includes:• Utilities for building spatial user interfaces.• Per-player configuratiion, enabling independent (or asymmetric) gameplay experiences.• Linear algebra / 3D math APIs for translating between multiple frames of reference.• Motion controller input management (including custom XR device support in Unity’s Input System).• Stereographic rendering for both Standard and scriptable (URP/HDRP) 3D render pipelines.• Provided developer support to strategic partners and third-party developers.Between SDK development cycles, I worked on several first-party game titles available on Tilt Five's website (e.g. mARbles, #KillAllZombies, T5 Demo Pack). Additionally, I developed proof of concept UX prototypes, SDK example scenes, and trade show & investor demos. In addition to SDK and game development, I provided engineering support to partners and third party developers. This included deployment and administration of our NodeBB forums instance, as well as moderation & support in the Tilt Five community Discord server.
