Say hello to Gaussian Splatting (GS) a game-changing 3D rendering technique that's been turning heads for its jaw-dropping realism and lightning-fast performance! Unlike the old-school methods that rely on polygons or complicated neural networks, GS takes a fresh approach by using millions of tiny, translucent ellipsoids known as Gaussian splats to create a scene. Think of each splat as a little pixel with its own personalitypacked with info like position, color, size, and transparency. When all these splats come together, they blend so smoothly youd swear theyre one seamless masterpiece, perfectly capturing the essence of the scene.How does Gaussian Splatting work?Creating a Gaussian Splat (GS) model is a bit like a high-tech version of photogrammetry. It all starts by capturing multiple photos or videos of an object or scene from different angles. These images are then analyzed to figure out the camera positions and generate a preliminary 3D point cloud of the scene, a process known as Structure from Motion (SfM). But here's where it gets interesting instead of sticking with basic points, each one in the cloud gets upgraded into a Gaussian splat. Think of these splats not as simple points, but as tiny ellipsoids, each with its own unique properties, ready to form part of the stunning 3D scene:Position: Determines where the splat is located in 3D space.Shape and Size: Dictates how the splat stretches or scales, allowing it to represent fine details.Color: Stores the splat's color information, which may vary depending on the viewing angle.Transparency: Defines how transparent the splat is, essential for blending multiple splats.
