Unsigned distance field
WebNov 11, 2024 · Reliance on Learned UDF Fields. The proposed method can mesh the zero-surface of an unsigned distance field. In practice however, UDF fields are approximated with neural networks, and we find it difficult to learn a sharp 0-valued surface for networks with small capacities. WebMar 27, 2024 · Volume rendering-based 3D reconstruction from multi-view images has gained popularity in recent years, largely due to the success of neural radiance fields (NeRF). A number of methods have been developed that build upon NeRF and use neural volume rendering to learn signed distance fields (SDFs) for reconstructing 3D models. However, …

WebPrevious works apply signed distance field and are limited to water-tight surfaces. In contrast, this paper proposes unsigned distance field that can represent both water-tight and non-water-tight surfaces. The experiments show that the proposed representation can accurately represent complex geometries as well as curves and manifolds ... WebMeshUDF: Fast and Differentiable Meshing of Unsigned Distance Field Networks. This is the PyTorch implementation of the preprint MeshUDF. We provide one dummy pre-trained UDF network and code for demonstrating our differentiable meshing procedure of open surfaces. The below instructions describe how to: Setup the Python environment.
WebInstead of aiming to represent a smooth and continuous surface in a binary voxel-grid, we propose to learn a Neural Unsigned Distance Field (NUDF) directly from the image. The small memory requirements of NUDF allow for high resolution processing, while the continuous nature of the distance field allows us to create high resolution 3D mesh … WebNeural Unsigned Distance Fields for Implicit Function Learning JulianChibane AymenMir GerardPons-Moll MaxPlanckInstituteforInformatics,SaarlandInformaticsCampus,Germany
