Illustrates the construction of four meshes. One method is to apply the Construct/Refine and ShowConnections modules to build a Cartesian mesh. This then can be transformed into a Polar mesh. The number of rings and spokes are not easily controlled by this method. Another way to create a polar mesh, suitable for displaying data in CGM coordinates, is to build a custom Cartesian mesh with Makeline modules and transform it into a Polar mesh.
The page {MakeMesh} uses the modules Construct, Refine, ShowConnections to generate a Cartesian mesh. The coordinate points are then interpreted as polar coordinates, and the mesh is rendered after the transformation to Cartesian coordinates.
