Bridging OpenGL and Unity: A Workflow for Mobile VR Application Development

This study proposes a systematic workflow for converting 3D assets generated in OpenGL into Unity-compatible formats and successfully applying them in mobile Virtual Reality (VR) environments. The proposed workflow was validated through experiments, achieving the export of static models in. obj format and dynamic models in. fbx format, integrating these models into Unity for constructing VR scenes, and ultimately exporting the VR scenes as. apk files for Android platforms. The results demonstrate that the workflow effectively preserves geometric structures, animation data, and material properties, enabling efficient rendering and smooth performance in both Unity and mobile platforms. This research provides an effective technical solution for addressing asset compatibility between OpenGL and Unity, laying a foundation for mobile VR application development.
