New method computes accurate signed distance functions using neural networks

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new variational method for accurately computing signed distance functions (SDFs) from point clouds. This approach explicitly incorporates the medial axis, which is the jump set of the SDF's gradient, by using a higher-order variational formulation. The method employs a phase field approximation to implicitly describe the medial axis and uses neural networks to approximate both the SDF and the phase field, demonstrating improved accuracy compared to existing methods.

    Medial Axis Aware Learning of Signed Distance Functions

    arXiv:2604.16512v2 Announce Type: replace-cross Abstract: We propose a novel variational method to compute a highly accurate global signed distance function (SDF) to a given point cloud. To this end, the jump set of the gradient of the SDF, which coincides with the medial axis of…
