The 3D Gaussian Splatting model is a technique used to represent and render three-dimensional scenes by approximating complex geometry and textures with a collection of Gaussian functions, or "splats." Each Gaussian splat is defined by parameters such as position, covariance, color, and opacity, which collectively contribute to a smooth, continuous representation of surfaces and volumetric details. This method enables efficient and realistic rendering of 3D environments by blending these splats, allowing for high-quality visualization with reduced computational complexity compared to traditional polygonal meshes. Gaussian splatting is especially useful in applications like real-time rendering, volumetric reconstruction, and augmented reality.
