Explore new techniques for load-balanced 3D Gaussian splatting that make large-scale scene reconstruction faster and more accessible. We introduce LoBE-GS, a framework that balances computation across partitions to achieve up to 2x faster training while maintaining quality—enabling real-time visualization and interactive exploration through Omniverse streaming.

As drones and missile strikes become major threats in modern warfare, traditional civil defense training often fails to build the procedural memory required for survival. We present VR CivicGuard, an immersive VR simulation that trains users in expert-informed air raid standard operating procedures. Developed through interviews with civil defense specialists, the system targets critical survival skills, including blast-mitigation posturing, emergency item collection, debris navigation, and drone evasion. A pilot study showed high usability and immersion, and participants trained with VR-CivicGuard significantly outperformed a control group. These findings highlight the effectiveness of expert informed VR for civil defense training.

Designing 3D curves with specified crossings and twistings often requires tedious view adjustments. We present a 3D curve development from 2D drawing with controlled crossings and twistings. We introduce a two-strand 2D diagram that lets users sketch with explicit crossing and twisting assignments. The system extracts feature points from the 2D diagram and uses them as 3D control points. It assigns the heights and over/under relationships of the control points via an optimization and then generates twisted 3D curves using B-splines. An interactive interface links the 2D diagram to the evolving 3D curves, enabling real-time iteration. We validate our method on diverse sketches, compare it with traditional 3D curve construction, and demonstrate its utility for elastic wire art via physics-based animation.

We present a novel streaming framework for interactive visualization of large-scale 3D Gaussian Splatting (3DGS) models, enabling smooth, real-time exploration on resource-constrained devices like mobile phones. Leveraging NVIDIA Omniverse Kit on an RTX 5090 GPU server, our backend client renders complex 3DGS scenes (e.g., 50M Gaussians, 8 GB) converted to USDZ via 3DGRUT, streaming video to a Three.js-based frontend using WebRTC for low-latency interaction. We enhance scene interactivity with metadata annotations from an Unreal Engine 5 tool, incorporating building bounding boxes and navigation paths sourced from OpenStreetMap, enabling clickable scene elements and 3D road-level navigation. Real-time camera pose synchronization between frontend and backend ensures consistent focus across platforms. Our approach achieves a stable 30 FPS on diverse devices, a 7-30x performance improvement over direct Three.js rendering.
