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…
OctaOctree Neural Radiosity for Real-time Glossy Material Rendering
Jierui Ren, Haojie Jin, Bo Pang +4
Modeling high-frequency outgoing radiance distributions remains a fundamental challenge in global illumination, especially for glossy and specular materials. Existing neural-based…
ChronoGS: Disentangling Invariants and Changes in Multi-Period Scenes
Zhongtao Wang, Jiaqi Dai, Qingtian Zhu +8
Multi-period image collections are common in real-world applications. Cities are re-scanned for mapping, construction sites are revisited for progress tracking, and natural regions…
BlitzGS: City-Scale Gaussian Splatting at Lightning Speed
Zhongtao Wang, Huishan Au, Yilong Li +6
Large-scale 3D Gaussian Splatting underpins digital twins, simulation, and aerial mapping, yet city-scale training remains computationally expensive even with multi-GPU execution b…
Vertex Features for Neural Global Illumination
Rui Su, Honghao Dong, Haojie Jin +3
Recent research on learnable neural representations has been widely adopted in the field of 3D scene reconstruction and neural rendering applications. However, traditional feature…
DualSplat: Robust 3D Gaussian Splatting via Pseudo-Mask Bootstrapping from Reconstruction Failures
Xu Wang, Zhiru Wang, Shiyun Xie +2
While 3D Gaussian Splatting (3DGS) achieves real-time photorealistic rendering, its performance degrades significantly when training images contain transient objects that violate m…
