The paper introduces Complex-Valued Quadratic Phase Gaussian (CVQPG), a new hologram representation that replaces standard 2D Gaussian splatting with 2D quadratic phase functions. CVQPG adds learnable parameters to control the curvature of these bases, and the authors demonstrate that it improves visual quality by +0.19 dB (RGB) and +0.33 dB (grayscale) over state‑of‑the‑art methods while keeping the same parameter count. Frequency‑domain analysis shows that CVQPG preserves the mid‑to‑high frequency band of natural images.

The paper introduces a compact neural appearance model for 3D Gaussian Splatting that replaces traditional low‑order spherical harmonics (SH) with a tiny shared MLP decoding per‑primitive latent codes. It compares SH with recent spherical appearance models, integrating all into a unified CUDA rasterizer and WebGL viewer, and demonstrates that the new neural representation reduces per‑primitive appearance storage from 192 to 28 bytes, speeds optimization by 1.3×, and improves reconstruction quality. The study also analyzes how different appearance parametrizations affect geometry recovery and the handling of non‑static scene content.
