Unified Gaussian Primitives for Scene Representation and Rendering

Understand

Searching for a unified scene representation remains a research challenge in computer graphics.

• Traditional mesh-based representations are unsuitable for dense, fuzzy elements and introduce additional complexity for filtering and differentiable rendering.
• Conversely, voxel-based representations struggle to model hard surfaces and high-frequency details.
• We propose a general-purpose rendering primitive based on 3D Gaussian distributions for unified scene representation, featuring versatile appearance ranging from glossy surfaces to fuzzy elements, as well as physically based scattering to enable accurate global illumination.
