                         particle-based fluid methods. Although particle-based methods are 
                         practical for computing level-sets that represent liquid 
                         interfaces, these methods are computationally expensive when the 
                         number of particles increases considerably due to the intense 
                         usage of particle approximations. This paper introduces a simple 
                         level-set approximation using a discrete indicator function (DIF) 
                         defined by counting particles inside grid cells. Our method is 
                         fast, easy to code, and can be adapted straightforwardly in 
                         particle-based solvers, even implemented in GPU. Moreover, we show 
                         the effectiveness of our approach through a set of experiments 
                         against prior surface reconstruction methods.",
