Rockstar🎓
Top SchoolJanine Liu is a 3D software developer with seven years of experience specializing in integrating geospatial 3D technologies into game engines at Cesium, where she contributes to flagship open-source projects like CesiumJS and the cesium-unreal plugin. She builds end-to-end features from back-end point-cloud to glTF conversion and renderer options to front-end engine plugins, shipping support for PNTS point clouds, dynamic camera controls, and Cesium ion asset integrations for Unity and Unreal. Her work spans C++ and engine-specific APIs, with hands-on improvements that optimize collision handling and 3D Tiles metadata processing in widely used repositories. Beyond coding, she writes tutorials, supports community forums, and creates demos that make advanced geospatial tech approachable to game and simulation developers. A former GPU programming and graphics TA, she pairs practical engine expertise with a solid academic foundation in digital media design.
