CityLLM: A framework for natural-language querying of semantic 3D city models

Semantic 3D city models provide rich geometric and semantic information, but remain challenging for non-experts and interdisciplinary researchers to access and query due to their complex structures and specialized data formats. To address this issue, we present CityLLM, a framewo...

Heat-Transfer-Driven Voxel-Based Simulation: An Exploratory GPU-Accelerated Framework for Urban-Scale 3D Fire Spread

The rapid growth of high-resolution 3D voxel datasets derived from LiDAR, BIM, and urban digital twin platforms has created new opportunities for volumetric environmental simulation. However, existing fire-spread models are often surface-based or computationally intensive for lar...
