3D Gaussian Splatting
Intro In Gaussian Splatting we carefully arrange a number of multi-variate Gaussians in space such that they represent a scene. Each Gaussian is assigned a color and can be rendered by evaluating it’s probability density function. By carefully tuning each Gaussian’s parameters to reconstruct ground truth views of the scene, it is possible to represent arbitrary scenes like the one in the two-dimensional example above. Extending this to the third dimension is particularly interesting because it allows us to render the scene from views that don’t exist in the ground truth, allowing us to synthesize novel views. ...
