About

Xi Zhao is a leading researcher in computer graphics and geometric modeling, with a primary focus on human-object interaction analysis and 3D scene synthesis. His seminal work on the Interaction Bisector Surface (IBS) introduced a groundbreaking geometric feature for classifying and retrieving character-object interactions, enabling precise multi-resolution representation of how humans engage with their environment. This paper has garnered 21 citations and remains a foundational reference in interaction retrieval. Zhao further advanced the field with his 2019 study on "Localization and Completion for 3D Object Interactions," which tackled the critical challenge of automatically determining where and what objects to place in existing 3D scenes. By overcoming the limitations of hand-crafted features and memory-intensive volumetric analysis, this work has significant implications for robotics motion planning and virtual environment design. Zhao's research bridges theoretical geometry with practical applications in animation, virtual reality, and autonomous systems, making him a key figure in the computational understanding of human-scene interactions.
