Digital latte art

In recent years, with the rapid development of graphics hardware and shader techniques, fluid simulation has become a feasible application, even for mobile devices. This study developed a latte art system based on fluid simulation, which can assist users with learning to create and design latte art digitally. With this application, users can redraw and undo patterns numerous times without wasting coffee. This study adopted an existing GPU based fluid simulation, modified the physical parameters to mimic the behavior of milk and coffee, and integrated a painting interface for users to create their own patterns. The results of this system are shown in Figure 1, and can facilitate a comparison with real latte art.
