Gaussian Splatting

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).



Update, the company Niantic (the owner of the powerful webAR platform 8thwall) has created a new open-source Gaussian Splat format .SPZ which is also called .JPG for 3D Gaussian Splats. A major advantage of the new format is that it is several times "smaller and lighter", and therefore reduces loading times and speeds up processing/rendering.
