We present GauStudio, a novel modular framework for modeling 3D Gaussian
Splatting (3DGS) to provide standardized, plug-and-play components for users to
easily customize and implement a 3DGS pipeline. Supported by our framework, we
propose a hybrid Gaussian representation with foreground and skyball background
models. Experiments demonstrate this representation reduces artifacts in
unbounded outdoor scenes and improves novel view synthesis. Finally, we propose
Gaussian Splatting Surface Reconstruction (GauS), a novel render-then-fuse
approach for high-fidelity mesh reconstruction from 3DGS inputs without
fine-tuning. Overall, our GauStudio framework, hybrid representation, and GauS
approach enhance 3DGS modeling and rendering capabilities, enabling
higher-quality novel view synthesis and surface reconstruction.

我们介绍了 GauStudio，一个新颖的模块化框架，用于建模 3D 高斯飞溅（3DGS），为用户提供标准化的即插即用组件，以便轻松定制和实现 3DGS 流程。支持我们的框架，我们提出了一种具有前景和天空球背景模型的混合高斯表示方法。实验证明，这种表示方法减少了无边界户外场景中的伪影，并改善了新颖视角合成。最后，我们提出了高斯飞溅表面重建（GauS）方法，它是一种从 3DGS 输入中进行高保真网格重建的新的先渲染再融合的方法，无需微调。总的来说，我们的 GauStudio 框架，混合表示方法和 GauS 方法增强了 3DGS 建模和渲染能力，实现了更高质量的新视角合成和表面重建。
