An incomplete R wrapper of the CGAL library

RCGAL

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

This package is abandoned! See MeshesOperations and SurfaceReconstruction.

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):

Dupin cyclide:

Clifford torus:

Orthocircle:

ICN5D's eight-like surface:

Stanford bunny:

Stanford dragon:
