WebJul 15, 2016 · Signed Distance Functions, or SDFs for short, when passed the coordinates of a point in space, return the shortest disance between that point and some surface. the sign of the return value indicates whether point is inside that surface or outside (hence signed distance function). let us look at an example. WebAbout. This page hosts the hg_sdf library for building signed distance functions (or more precise: signed distance bounds). Those are a very elegant and flexible representation of geometry that can be rendered or otherwise processed. Roughly, coded SDFs are to triangle meshes or voxels what vector graphics are to pixels.
