Figure 1. We show three groups of shape reconstruction results generated by NDF [10] (in cyan) and our proposed 3PSDF (in gold) respectively. Our method is able to faithfully reconstruct high-fidelity, intricate geometric details including both the closed and open surfaces, while NDF suffers from the meshing problems. Each NDF result is reconstructed from a dense point cloud containing 1 million points while ours are reconstructed using an equivalent resolution.
