Hatching for Metaball Surfaces
Ferenc Tükör · Repository of the Academy's Library (Library of the Hungarian Academy of Sciences) · 2014
This paper presents a highly parallel algorithm for the stylized, real-time display of fluids and smoke.We use metaballs to define a fluid surface from a particle-based fluid representation, but instead of the costly complete reconstruction of this surface, we only trace the motion of random seed points on it.Hatching strokes are extruded along the lines of curvature.We propose methods for hidden stroke removal and density control that maintain animation consistency.
