Representing shapes as level sets of neural networks has been recently proved to be useful for different shape analysis and reconstruction tasks So far, such representations were computed using either: (i) pre-co
本文提出了一种用于改进神经隐函数 3D 表示中采样和正则化的混合模型，利用 iso-points 作为神经隐函数的显式表示，使训练时能够实时计算并更新采样点，以捕获重要的几何特征和优化几何约束，提高重建质量和拓扑准确性。实验结果表明，相比现有方法，该方法可以更快地收敛、更好地泛化、更准确地恢复细节和拓扑结构。
