DeepSDF: Learning Continuous Signed Distance Functions for ...
tion is a continuous function that, for a given spatial point, outputs the point’s distance to the closest surface, whose sign encodes whether the point is inside (negative) or out-side (positive) of the watertight surface: SDF(x) = s : x∈ R3, s ∈ R. (1) The underlying surface is implicitly represented by the iso-surface of SDF(·) = 0.
