The number of primitives used to represent the scene affects reconstruction quality, storage, and rendering cost. How to select this number automatically across captu…

• Light Field Primitive for Novel View Synthesis

  Liang Chen, Jiahui Ning, Xun Jiang, Xing Xu, Jimmy Ren, Fenglei Fan, Heng Tao Shen · 28 September 2026

  We present Light Field Primitives (LFP), a formulation for novel view synthesis that replaces the dense ray database with a compact set of differentiable primitives in the classical two-plane parameterization. Each primitive condenses a group of rays into one learned record, and its response to a qu…

• From Mono to Stereo: Accelerating Binocular Gaussian Splatting via Reprojection and Selective Patching

While 3D Gaussian Splatting (3DGS) enables high-quality real-time r…

• Only What Was Seen: Observation-Gram Compaction of View-Dependent Appearance in 3D Gaussian Splatting

  Krzysztof Pietroszek · 25 September 2026

  Most of the memory of a 3D Gaussian Splatting model holds spherical-harmonic colour coefficients, yet each Gaussian is seen only from the narrow cone of directions of the training cameras. We turn this into a distortion metric that other compressors can adopt: a per-Gaussian observation Gram matrix,…

• PlenoCI: Plenoptic CharacterIstics for View Dependence Aware Change Classification

  Jason Lai, Chamuditha Jayanga Galappaththige, Niko Suenderhauf, Dimity Miller, Donald G. Dansereau · 25 September 2026

  Radiance field representations such as 3D Gaussian Splatting (3DGS) natively encode complex visual phenomena such as occlusions and view dependence, but they are inherently underconstrained. Independently optimized reconstructions converge to different primitive configurations, even in unchanged reg…

• ADATEX4D: adaptive texture capacity allocation for 4D gaussian splatting

  De Jiang, Peiqiang Wang, Kehong Yuan, Shaohua Ma · 25 September 2026

  Textured Gaussians improve local appearance capacity, but assigning the same texture resolution to every primitive wastes storage on low-detail or weakly visible regions. We introduce AdaTex4D, an adaptive texture-capacity module for deformation-based 4D Gaussian Splatting. Each Gaussian carries pac…

• RoomLight: A 2.5D Illumination Prior for Indoor Environments

  Andreea Ardelean, Bernhard Egger · 24 September 2026

  Haoyuan Yue, Fengyuan Ye, Ziyin Li · 24 September 2026

  We present GaussPDE, a framework that injects physically structured partial differential equation (PDE) dynamics into pretrained 3D Gaussian scenes without mesh extraction, voxelization, or retraining. Our key observation is that PDE rendering requires not only accurate appearance, but also a reliab…

• 4DGS-JEPA: Temporally Compositional Joint-Embedding Prediction for Dynamic Gaussian Splatting

  Yongchao Huang · 23 September 2026

  Dynamic Gaussian Splatting provides an explicit representation of evolving 3D scenes, but existing approaches are primarily optimized for reconstruction, future-state generation, or rendering rather than for learning reusable predictive dynamics. We propose 4DGS-JEPA, a Gaussian-native joint-embeddi…
