Previous experiments in interfaces for **SDF** authorship have re-lied on node-based or textual workflows [Lindborg et al. 2017] [Reiner et al. 2011]. Recently, SDFs have been used in 3D authorship. The upshot is that we don't need to do any meshing; all we need is a signed distance function (**SDF**) to the surface. Let's start by defining the **SDF** to the "backbone", which is a line segment from x = 0 1 x=0\ldots 1 x = 0 1. See this great video from **Inigo** **Quilez** for a derivation of this **sdf**..
