In this paper, we introduce DreamGaussian4D (DG4D), an efficient 4D generation framework that builds on Gaussian Splatting (GS). Our key insight is that combining explicit modeling of spatial transformations with static GS makes an efficient and powerful representation for 4D generation. Moreover,...
In this work, we propose 4D radiative Gaussian splatting (4DRGS) to achieve high-quality reconstruction efficiently. In detail, we represent the vessels with 4D radiative Gaussian kernels. Each kernel has time-invariant geometry parameters, including position, rotation, and scale, to model static ...
Why has there been so much attention on 3D Gaussian Splatting? The obvious answer is that the results speak for themselves - it's high-quality scenes in real-time. However, there may be more to story.There are many unknowns as to what else can be done with Gaussian Splatting. Can...
What is 3D Gaussian Splatting? 3D Gaussian Splatting is, at its core, a rasterization technique. That means: Have data describing the scene. Draw the data on the screen. This is analogous to triangle rasterization in computer graphics, which is used to draw many triangles on the screen....
