Fixed-Budget Gaussian Volume Encoding with Structure-Aware Allocation

This work encodes scalar fields as anisotropic Gaussian primitives under a fixed budget that serves every subsequent visualization state - supporting post-hoc transfer-function, colormap, lighting, and viewpoint changes without re-encoding.

3D Field Data Reduction with Adaptive Sample-Based Gaussian-Encoded Reconstruction

Across structured, unstructured, and particle data, the sample-based formulation improves reconstruction accuracy with measurably fewer primitives in comparison to prior formulations, achieving up to 4.8 dB higher PSNR with an approximate 44x reduction in primitive count.

Cross-Platform Benchmark of Neural 3D Reconstruction for Autonomous Laboratory Robots

This work presents a systematic compute-platform benchmark of neural 3D reconstruction methods, evaluating NeRF and 3D Gaussian Splatting training and rendering on GPU-enabled computing devices, and place Meta's SAM3D single-image reconstruction on the same axes to quantify its latency and fidelity gap relative to per-...
