Wrapping the C++ library **CGAL** in R. Convex hull, Delaunay tessellation, surface reconstruction.

## Some examples of Poisson reconstruction

*Toroidal helix:*

*Spider cage:*

*Solid Möbius strip:*

*Hopf torus:*

The Hopf torus is not very smooth. We can make it a bit smoother by reducing 

the `spacing` parameter of the `PoissonReconstruction` function:

Here is a series of three images which show the effect of this `spacing` 

parameter (0.05, 0.02, 0.005):

## Blog post

I wrote a [blog post](https://laustep.github.io/stlahblog/posts/SurfaceReconstruction.html) 

devoted to surface reconstruction (using **RCGAL**, the ancestor of **SurfaceReconstruction**).
