Photogrammetry and 3D Gaussian Splatting for 4D plant growth capture and greenhouse digital twins [PDF]
Biodiversity Data JournalPlants are inherently three-dimensional organisms, yet many biologically important traits remain difficult to document using two-dimensional photography because of self-occlusion and complex plant architecture.

Beyond Spherical Harmonics: Rethinking Appearance Models for Radiance Reconstruction
Computer Graphics Forum, EarlyView.Abstract View‐dependent appearance modeling remains a challenging problem in novel‐view synthesis and reconstruction. Accurately representing complex angular effects often requires substantial memory and computational resources. For new learning‐based methods, a common approach is to rely on Spherical Harmonics (SH).

FlowGS: Controlling Information Flow for Graph‐Based Interaction in 3D Gaussian Splatting
Computer Graphics Forum, EarlyView.Abstract 3D Gaussian Splatting (3DGS) has recently enabled real‐time, high‐quality novel view synthesis. However, its formulation treats each Gaussian independently, lacking explicit information exchange between neighboring elements and limiting its ability to capture local structure.

Arbitrary Optics for Gaussian Splatting Using Space Warping
Journal of ImagingDue to recent advances in 3D reconstruction from RGB images, it is now possible to create photorealistic representations of real-world scenes that only require minutes to be reconstructed and can be rendered in real time.

GAGS: Gradient-Guided Adaptive Gaussian Splatting for Efficient and Geometry-Regularized Surface Reconstruction [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesWhile 3D Gaussian Splatting (3DGS) has advanced surface reconstruction, existing implementations face critical challenges in memory efficiency and geometric fidelity. Current approaches like PGSR generate excessive Gaussian primitives due to uncontrolled

Advances in 4D Representation: Geometry, Motion, and Interaction
Computer Graphics Forum, EarlyView.We survey 4D representation through three key pillars — geometry, motion, and interaction — offering a selective, representation‐centric perspective to guide researchers in choosing and customizing the right 4D representation for their tasks. Abstract We present a survey on 4D generation and reconstruction, a fast‐evolving subfield of computer graphics
