Key Points

To develop a neural framework for signed and unsigned distance fields that guarantees conservativeness with respect to 3D shapes by never overestimating the true distance.
Designed neural network architectures with guaranteed Lipschitz continuity.
Integrated a tailored training data selection scheme with a constrained optimization strategy to enforce strict conservativeness.
Guaranteed that the zero-level set acts as a conservative bounding volume for target 3D shapes without distance overestimation.
Achieved tighter shape approximations and preserved exact distance data compared to existing conservative neural implicit representations.
