The field of 3D scene reconstruction and geometry processing is rapidly advancing, with a focus on developing novel methods for realistic and view-consistent scene representation. Recent research has explored the use of Gaussian Splatting, Neural Radiance Fields, and other techniques to improve the accuracy and efficiency of scene reconstruction. One notable direction is the integration of multiple types of geometrical primitives, such as Gaussian ellipses and ellipsoids, to better represent complex object surfaces. Additionally, the use of wavelet decomposition and other optimization techniques has shown promise in improving the quality of reconstructed scenes. Noteworthy papers in this area include RePaintGS, which proposes a novel 3D scene inpainting method that reliably produces realistic and perceptually consistent results, and Wavelet-GS, which integrates wavelet decomposition into 3D Gaussian Splatting to improve the quality of complex scene reconstruction. Other notable works, such as OffsetCrust and A Mixed-Primitive-based Gaussian Splatting Method, have also made significant contributions to the field of geometry processing.
