Geospatial Research Lab to Present Novel Rendering Technique at SIGGRAPH 2025

The Geospatial Research Lab at the USC Institute for Creative Technologies (ICT) will present its latest technical paper tomorrow at SIGGRAPH 2025, the premier conference and exhibition on computer graphics and interactive techniques.

The paper, Deformable Beta Splatting (DBS), will be featured in the “Splatting Bigger, Faster, and Adaptive” session on Wednesday, August 13, from 10:45 a.m. to 12:35 p.m. PDT in Rooms 301–305 of the West Building. The team’s presentation is scheduled for 11:35–11:45 a.m. PDT. Full session details are available in the SIGGRAPH 2025 conference schedule.

Authored by Rong Liu, Dylan Sun, Meida Chen, Yue Wang, and Dr. Andrew Feng, DBS introduces a new approach for real-time radiance field rendering. The method uses deformable Beta Kernels with adaptive frequency control for both geometry and color encoding. This enables accurate capture of complex geometries and lighting while using 45 percent fewer parameters and rendering 1.5 times faster than the current benchmark, 3DGS-MCMC.

By achieving high fidelity with greater computational efficiency, DBS offers clear advantages for large-scale, real-time visualization—an area of increasing importance for simulations and virtual environments.
