ECE Team Wins Best Reproducible Paper Award at ACM MMSys 2025
A research team led by Guodong Chen, PhD’29, computer engineering, won the Best Reproducible Paper Award at ACM MMSys 2025 for their research on “TVMC: Time-Varying Mesh Compression Using Volume-Tracked Reference Meshes.” TVMC addresses the compression of complex 3D mesh sequences with changing topology without sacrificing real-time performance, which is a longstanding challenge in AR/VR and volumetric streaming. It enables higher compression ratios and significantly faster decoding compared to state-of-the-art codecs like Google Draco and V-DMC 4.0 by introducing a volume-tracking approach and extracting self-contact-free reference meshes.
TVMC also reflects a broader shift toward open, reproducible, and practical systems that support real-time, low-latency graphics for applications ranging from telepresence to spatial computing. Its recognition underscores the growing importance of robust 3D compression as the backbone for next-generation XR experiences. The TVMC team made their implementation publicly available, reinforcing the reproducibility and transparency essential for community adoption and future standardization.
