====Isomesh====
The figures on this page include isomeshes. The isomesh is a mesh representing an  isosurface. An isosurface is a surface placed at a specific value of a continuous parameter, so that it represents the boundary between higher and lower values of that parameter. Perhaps a geographic map is a more familiar example, where each [http://wiki.gis.com/wiki/index.php/Isoline isoline] is a contour line joining positions with the same elevation. In an electron density map, an isomesh joins positions with the same electron density, for example, 1 sigma.
