Gaussian Splatting

The technique of 3D Gaussian Splatting is a groundbreaking method in the field of computer graphics, presenting an inventive approach for rendering photorealistic scenes in real-time. This approach has garnered considerable interest for its capability to manage scenes derived from various photos or videos, striking a balance between the requirement for exceptional visual quality and the challenges of real-time performance, particularly when dealing with entire scenes rendered at 1080p resolution.

Fundamentally, 3D Gaussian Splatting operates as a form of rasterization. While conventional computer graphics typically employ the drawing of triangles on the screen for rasterization, Gaussian Splatting takes a different approach. In this technique, the essential building block is the Gaussian. Each Gaussian is characterized by its position (XYZ coordinates), covariance (a 3x3 matrix influencing its stretch or scale), color (RGB values), and alpha (transparency level).
