+ This is the official implementation of the T-PAMI 2025 paper "PonderV2: Pave the Way for 3D Foundation Model with A Universal Pre-training Paradigm".

+
26
+ [PonderV2](https://arxiv.org/abs/2310.08586) is a comprehensive 3D pre-training framework designed to facilitate the acquisition of efficient 3D representations, thereby establishing a pathway to 3D foundational models. It is a novel universal paradigm to learn point cloud representations by differentiable neural rendering, serving as a bridge between 3D and 2D worlds.
