Interoperability and optimization issues in mixed reality setup for complex built heritage

The research aims to investigate an appropriate mixed reality setup for complex built heritage assets. The process looks into a number of phases, starting from recording, visualization, and interaction, hence from the data processing phase to mixed reality environment management. By comparing the interoperability of 3D file formats, the workflow is optimized to transmit designated data efficiently and seamlessly. The virtual environment setting for built heritage with high-variance mesh is discussed in detail. Interoperability is also highlighted by using multi-level model proxies and resolution variables to decrease the dependence of computation, reducing latency in runtime, and enhancing the interaction input and response agility. Based on the realistic rendering setup for a better sense of presence, the research proposes three sets for level of detail (LOD) to optimize the visualization and performance on MR devices. Limitations and challenges were identified in the workflow with manual reconstruction steps.
