Xinyue Liu developed model axis orientation support for the Autodesk/hydra-viewport-toolbox repository, focusing on improving 3D graphics workflows in C++. By introducing an isZAxisUp flag within the ModelParams structure, Xinyue enabled the software to accurately store and interpret a model’s up-axis information, specifically addressing the needs of Z-up models. This technical enhancement allows for correct orientation and viewport handling, reducing misrenderings and minimizing manual adjustments in asset pipelines. The work established a foundation for future axis normalization across tools, demonstrating a thoughtful approach to software engineering challenges in 3D graphics and contributing to more robust model interoperability.
