### Description

This example loosely follows the most excellent paper by Curless and
Levoy: ["A Volumetric Method for Building Complex Models from Range
Images."](https://graphics.stanford.edu/papers/volrange). First it estimates normals from the points, then creates a signed distance field, followed by surface extraction of the zero-level set of the distance field.

This is a demo version of [ExtractSurface](../ExtractSurface). It displays some sampling of the normals with arrows. It also uses a different color for the front and back surfaces.

The image was created using the Armadillo dataset, `src/Testing/Data/Armadillo.ply`.
