Gaussiancube
Overview :
GaussianCube is an innovative 3D radiance representation method that significantly advances 3D generative modeling through its structured and explicit representation. This technology achieves high-precision fitting by utilizing a novel density-constrained Gaussian fitting algorithm and optimal transport methods, rearranging Gaussian functions onto a predefined voxel grid. Compared to traditional implicit feature decoders or spatially unstructured radiance representations, GaussianCube boasts fewer parameters and higher quality, making 3D generative modeling more accessible.
Target Users :
GaussianCube is suitable for researchers and developers in the field of 3D modeling, computer graphics, virtual reality, and augmented reality, especially those seeking higher accuracy and fewer parameters in 3D generative modeling.
