In this study, the authors address the challenges of rendering large-scale 3D Gaussian Splatting (3DGS) models on consumer-grade devices in real-time. They introduce GS-Cache, an innovative framework that integrates advanced 3DGS representation with a highly optimized rendering system to support immersive experiences, such as virtual reality (VR). GS-Cache improves performance, reduces latency, and lowers GPU […]
