Overview
VolumetricSimple is a lightweight and user-friendly add-on module for SMPL(-X)-based body models, enabling seamless volumetric extension. With just a single line of code, users can extend SMPL models with volumetric functionalities. After completing the forward pass, they gain access to key volumetric functionalities, including SDF queries, self-intersection loss, and collision penalties. This implementation maintains full compatibility with existing SMPL-based reconstruction and perception applications.
