/**\brief Reconstruct a surface using its points and point normals.
  *
  * Given a surface with point normals, the dimensions of an
  * enclosing voxel grid and a radius of influence, apply a
  * variant of Curless et al.:
  *
  * Brian Curless and Marc Levoy. 1996. A volumetric method for
  * building complex models from range images. In Proceedings of
  * the 23rd annual conference on Computer graphics and
  * interactive techniques (SIGGRAPH ’96). Association for
  * Computing Machinery, New York, NY, USA, 303–312.
  * DOI:https://doi.org/10.1145/237170.237269
  *
  * This method constructs an implicit signed distance function
  * from the input dataset's points and point normals, using the
  * radius of influence to define a local neighborhood for
  * computing the signed distance. It then computes an isocontour
  * at distance = 0 using a variant of the Flying Edges technique:
  *
  * W. Schroeder, R. Maynard and B. Geveci, "Flying edges: A
  * high-performance scalable isocontouring algorithm," 2015 IEEE 5th
  * Symposium on Large Data Analysis and Visualization (LDAV), Chicago,
  * IL, 2015, pp. 33-40, doi: 10.1109/LDAV.2015.7348069.
