WebMar 30, 2024 · Specifically, we augment a neural signed distance function (SDF) representation with a neural directional distance function (DDF) that is defined on a unit sphere enclosing the 3D shape (see Fig. 2).Our main motivation for incorporating the DDF representation is to obviate the need for computationally expensive sphere tracing when … In mathematics and its applications, the signed distance function (or oriented distance function) is the orthogonal distance of a given point x to the boundary of a set Ω in a metric space, with the sign determined by whether or not x is in the interior of Ω. The function has positive values at points x inside Ω, it decreases in value as x approaches the boundary of Ω where the signed distance function i…
