PURPOSE: A fluidic shape presentation device and a method thereof are provided to reduce time for three-dimensional visualization of fluid by deciding a surface particle with density of particles of an object and forming splat on the surface particle. CONSTITUTION: An object forming unit(110) forms an object of a plurality of particles within 3D space. An object surface decision unit(120) decides a surface particle of a surface of the object. A splat forming unit(130) forms splat of polygon in an opposite direction of a normal vector direction calculated about the surface particle. The splat is separated from the surface particle as a preset reference distance. A splat control unit(140) moves a location of each vertex of the splat in the normal vector direction.
