Neural Rendering II: 3D Gaussian Splatting and Research Practice

Describe how a 3D scene is represented by a collection of explicit, anisotropic 3D Gaussian primitives.

Explain the mathematical process of projecting a 3D Gaussian onto a 2D image plane.

Compare and contrast the trade-offs of NeRF (implicit, slow render) vs. 3D Gaussian Splatting (explicit, fast render).

Decompose the 3D Gaussian Splatting paper into its problem statement, core method, and key results.

Apply a systematic framework to analyze a research paper: identify problem, distill mathematical intuition, and critique experiments.

Identify the limitations of a given research paper (e.g., NeRF, 3DGS).

Propose a concrete follow-up research question or potential improvement based on a paper's identified limitations.
