4D Gaussian Splatting

4D Gaussian Splatting is a holistic representation for dynamic scenes, allowing for.

4D Gaussian Splatting is a holistic representation for dynamic scenes, allowing for real-time rendering at high resolutions. It is designed for professionals working with dynamic scenes, such as those in the film or video game industry.
The 4D Gaussian Splatting method involves a novel explicit representation containing both 3D Gaussians and 4D neural voxels. A decomposed neural voxel encoding algorithm is used to efficiently build Gaussian features from 4D neural voxels, and a lightweight MLP is applied to predict Gaussian deformations at novel timestamps.
Professionals working with dynamic scenes, such as filmmakers or video game developers, can benefit from 4D Gaussian Splatting. It allows for real-time rendering at high resolutions, making it ideal for applications where speed and quality are crucial.
