Fluid behaviors are fascinating, which are of great interests by theorists, practitioners and artists. From the visual perspective, the motion and structure of fluids form the complex and beautiful patterns in nature. Simulating these visual patterns in different scenarios can be very interesting, which has the potential to benefit a lot of studies in different areas. In this talk, I will review our efforts in the past many years on developing new techniques for simulating both classical and quantum fluid flows, with computer graphics techniques to present the simulated results. In particular, for classical fluids, we have been focused on developing kinetic approaches originated from statistical mechanics, which are accurate and efficient in producing a variety of fluid flow phenomena, and we will illustrate how we progress this field. We also believe that such approaches can be appealing as the next-generation simulation technique in the future. For quantum fluids, we more focused on the visual structure, where we have developed new vortex identification methods to uncover the complex structure inside the high-resolution quantum fluid data sets, with real-time visualization and different types of interactions for intuitive exploration.  This is the first visual presentation of large-scale vortex structures in quantum fluids now in the world. Such a series of researches can lead to different kinds of applications, where we are pushing forward to apply our results to scientific study, special effects in movies, new design of unmanned aerial vehicles, urban architecture design, medical diagnosis, as well as training for intelligent robots. Many animation videos for the motion and structure of fluids will be shown during the talk.



Prof. Xiaopei Liu is now an assistant professor at School of Information Science and Technology, ShanghaiTech University, affiliated with the center for Virtual Reality and Visual Computing as well as the center for Data Science and Machine Intelligence. He is also the person-in-charge of the Unmanned Aerial Vehicle Computing Lab (UAV-CL) at ShanghaiTech. He obtained his Ph.D. degree on computer science and engineering from The Chinese University of Hong Kong (CUHK), and then worked as a Research Fellow at Nanyang Technological University (NTU) in Singapore, where he started the multi-disciplinary research, and collaborated with School of Mechanical & Aerospace Engineering and Institute of Advanced Studies of NTU for research on fluid simulation and visualization, both on classical and quantum fluids. Most of his publications are top journals and conferences, which cover multiple disciplines, such as ACM TOG, ACM SIGGRAPH Asia, IEEE TVCG, APS PRD, AIP POF, etc. Prof. Xiaopei Liu is now working on physically-based simulation & visualization techniques, with applications to many areas such as fundamental science, visual effects, UAV design, medical diagnosis, as well as robotic learning. He is also conducting research and system-level implementations on low-altitude UAV navigation and its intelligence.
