3D Gaussian Splatting - A New Frontier In 3D

Updated: Oct 21, 2023

In the rapidly evolving domain of 3D art and software development, staying abreast of the latest technologies is not just advantageous, it's imperative. One such groundbreaking technology is 3D Gaussian Splatting, which has emerged as a transformative tool for novel-view synthesis of scenes captured via photos or videos​​.


This technology, a class of Radiance Field methods akin to Neural Radiance Fields (NeRFs), is particularly geared towards real-time rendering of photorealistic scenes from small image samples, a feat that has been lauded for its potential to significantly advance graphics rendering​​.

What is 3D Gaussian Splatting?


At its core, 3D Gaussian Splatting is a technique used to create 3D scenes from a collection of 2D images. By simply utilizing a video or a set of photos of a scene, one can derive a 3D representation of it, enabling the re-rendering of the scene from any desired angle​. The technology manifests a point cloud of 3D Gaussians, which are essentially ellipsoids in 3D space characterized by a center, scale, rotation, and “softened edges”.


Each 3D Gaussian is optimized alongside a (view-dependent) color and opacity, culminating in a detailed 3D rendering.

How to Use 3D Gaussian Splatting?

Utilizing 3D Gaussian Splatting involves three primary steps:

  1. Recording the Scene: The initial step necessitates recording the scene through a video or individual photos, capturing different angles to foster a more refined model.

  2. Obtaining Camera Poses: This step is pivotal as it entails obtaining the position and orientation of the camera for each frame, known as the camera pose.

  3. Training the 3D Gaussian Splatting Model: Post the aforementioned steps, the 3D Gaussian Splatting model is trained to generate the final 3D representation​.

Importance of 3D Gaussian Splatting


The hallmark of 3D Gaussian Splatting is its ability to deliver real-time rendering of photorealistic scenes, a major leap forward especially pertinent to game developers​. Unlike NeRFs, this technology enables real-time rendering as scenes are represented by simpler colored "blobs", making it easier to display in real time. Moreover, the algorithm is devoid of neural networks, which facilitates a more streamlined rendering process​.
