Detailed Description

A class describing an unstructured mesh. This class contains the shared functionality between 1d or 2d meshes.

MeshKernel can handle 2d meshes and 1d meshes. Algorithms require certain mappings to be available for both Mesh1D and Mesh2D, such as a mapping listing all edge indices connected to a particular node. The methods computing these mappings are shared between Mesh2D and Mesh1D, and implemented in the Mesh base class. The Mesh base class also contains other common data members, such as the node coordinate, the edges definitions, the face definitions and the mesh projection. The Mesh base class has the following responsibilities:

Construct the mesh faces from the nodes and edges and other mesh mappings required by all algorithms (Mesh::FindFaces). Mesh::FindFaces is using recursion to find faces with up to 6 edges (meshkernel::Mesh::m_maximumNumberOfEdgesPerFace).
Supporting mesh editing, namely:
- Node merging
- Node insertion
- Moving a node
- Inserting edges
- Deleting edges
- Merging nodes (merging two nodes at meshkernel::mergingDistance). This algorithm use an r-tree for inquiring adjacent nodes, see later.
Converting a curvilinear grid to an unstructured mesh (converting constructor).
Holding the mesh projection (cartesian, spherical, or spherical accurate).
Making a quad mesh from a polygon or from parameters.
Making a triangular mesh from a polygon. This algorithm introduces a dependency on the Richard Shewchuk Triangle.c library, added as an external component in extern/triangle folder.

The public interface of the mesh class contains several algorithms, which modify the mesh class members when they are called.
