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. WebNov 4, 2024 · DUDE is a disentangled shape representation that utilizes an unsigned distance field (uDF) to represent proximity to a surface, and a normal vector field (nVF) to represent surface orientation. We show that a combination of these two (uDF+nVF) can be used to learn high fidelity representations for arbitrary open/closed shapes.
