Webthe reinitialization equation φt +sign(φ)( ∇φ −1) = 0 (13) for a short period of time. This equation can be discretized in a similar way as the level set equation, and the discontinuous sign function is smoothed over a few grid cells. Another option is to explicitly update the nodes close the boundary, by for Lithography (from Ancient Greek λίθος, lithos 'stone', and γράφειν, graphein 'to write') is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and map…
