3D City Modeling

· 3D City Generation from A Single Satellite Image

· 3D VR Scene in Different LODs

A study where participants interact with VR scenes at different Levels of Detail (LOD), collecting interaction data to explore the relationship between human behavior and LOD fidelity. The research investigates how varying levels of visual complexity influence user perception, navigation patterns, and decision-making in virtual environments.

· 3D Scene Reconstruction of HKUST-GZ using 3D Gaussian splatting

Spatiotemporal Statistical Modeling

· gdverse: An R package for spatial stratified heterogeneity family

Analyzing spatial factors and exploring spatial associations based on the concept of spatial stratified heterogeneity, while also taking into account local spatial dependencies, spatial interpretability, complex spatial interactions, and robust spatial stratification. Additionally, it supports the spatial stratified heterogeneity family established in academic literature.
