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

A new module called S2MDF has been introduced to address the limitations of compositional implicit surface representations that utilize Signed Distance Fields (SDFs). This module enforces a hard constraint to prevent interpenetration of geometries, which is a common issue in existing methods that rely on soft penalty terms.

The development of S2MDF is significant as it allows for the creation of physically plausible multi-object representations without the need for architectural changes, enhancing the reliability of 3D modeling and rendering processes in various applications.
