S2MDF: A Plug-And-Play Layer for Intersection-Free Multi-Object Signed Distance Fields 事件

S2MDF: A Plug-And-Play Layer for Intersection-Free Multi-Object Signed Distance Fields arXiv:2605.29761v1 Announce Type: new Abstract: Compositional implicit surface representations model scenes as collections of objects, each encoded by a Signed Distance Field (SDF). A fundamental limitation of this approach is that multiple SDFs can produce geometries that interpenetrate, violating physical plausibility. Existing mitigation strategies rely on soft penalty terms that reduce but do not eliminat
