Point clouds

The vertices of meshes are contained in a reference set of points in \(\mathbb{R}^{3}\) (a point cloud). Since points of \(\mathbb{R}^3\) are modelled by objects of type R3 (which is an alias of Vectors of small dimension SmallVector<double,3>), a point cloud is modelled by an object of type Nodes which essentially consists in a dynamically allocated array of objects of type R3.

Point clouds are systematically composed of points of type R3, even when considering problems and meshes in \(\mathbb{R}^{2}\).

Standard use-cases only involve one single instance of Nodes which is a reference point cloud used by all Mesh and Element entities.
