We use VR interactive technology to visualize 3D CFD data. Through volume rendering techniques, we can observe the distribution of simulated values such as temperature and velocity. We optimize data transfer and switching to observe dynamic simulation results. By calculating pathlines on the fly, we present the directionality within the 3D flow field. Users can use VR controllers to place particles at any position to observe flow direction in areas of interest.

We integrate volume rendering techniques and real-time pathline calculations with optimized data access and display using VR interaction technology. Usingdata surrounding Taiwan's oceans simulated by ocean current model as an example, we can observe in real-time the distribution of simulated scalar values such as temperature and the directionality of vector data such as velocity in the dynamic 3D flow field. It also provides the interactivity to observe any position within the 3D flow field, providing a valuable utility for research and judgment for developing ocean energy for net zero emissions in our country.

Through VR technology, we can observe the dynamic results within the 3D flow field simulation. The VR interaction allows for intuitive observation and manipulation within the scene, enabling analysis of a 3D numerical wind tunnel or flow field, which becomes part of the digital twin process. In the future, by combining this with AI-powered real-time simulations, we can conduct instant product modifications and designs related to flow fields or wind tunnels, thereby improving efficiency.
