This is an algorithm for converting a signed distance field to a triangle mesh. It's not trivial to implement. Dual Contouring is highly prone to creating defective meshes with self intersections, which is bad for rendering, 3D printing, import into OpenScad. You can spend years trying to fix these problems. And Matt has put years of work into implementing the libfive meshing algorithm.

Any idea what that means? Is this "Dual Contouring of Hermite Data" actually this benefitical?
