Occlusion-Point Reuse for Ray-Traced Ambient Occlusion and Shadow
Haojie Jin, Fujia Su, Zehui Lin +9
Ambient occlusion (AO) and soft shadows are critical visibility cues for spatial perception in real-time rendering. Hardware ray tracing provides a direct way to evaluate these eff…
PTIR-GS: Path-Traced Inverse Rendering with Global Illumination in 3D Gaussian Fields
Junke Zhu, Hao Zhang, Yutian Zhu +6
Ray tracing enables 3D Gaussian fields to serve as a representation for physically based light transport. Faithful inverse rendering requires forward rendering and backward optimiz…
G2G: Exploiting Intra-Group Geometry for Inter-Group Pose Estimation
Yufei Wei, Shuhao Ye, Chenxiao Hu +5
Recovering the relative 6-DoF pose between two image groups underlies cross-sequence relocalization and multi-camera rig odometry. Each group carries known intra-group geometry fro…
BEV-ODOM2: Enhanced BEV-based Monocular Visual Odometry with PV-BEV Fusion and Dense Flow Supervision for Ground Robots
Yufei Wei, Chenxiao Hu, Wangtao Lu +5
Scale-consistent ego-motion estimation is fundamental for autonomous ground robots. Bird's-Eye-View (BEV) representation naturally addresses the scale drift problem of monocular vi…
Real-time Global Illumination for Dynamic 3D Gaussian Scenes
Chenxiao Hu, Meng Gai, Guoping Wang +1
We present a real-time global illumination approach along with a pipeline for dynamic 3D Gaussian models and meshes. Building on a formulated surface light transport model for 3D G…
Hypothesis Testing for Progressive Kernel Estimation and VCM Framework
Zehui Lin, Chenxiao Hu, Jinzhu Jia +1
Identifying an appropriate radius for unbiased kernel estimation is crucial for the efficiency of radiance estimation. However, determining both the radius and unbiasedness still f…
