This paper presents a novel meshless framework for line art rendering of surfaces with complex geometry and arbitrary topology. Unlike the usual frameworks, the line placement is achieved using an inviscid fluid flow simulation to compute the direction fields over the surface model. To perform the computational fluid dynamics, we utilize the Smoothed Particles Hydrodynamics (SPH) method. We demonstrate the simplicity and effectiveness of our method illustrating a variety of complex surfaces.
