• Abstract

  Smoothed Particle Hydrodynamics (SPH) is one of the most popular meshless methods in computational fluid dynamics. Since its conception, it has been the object of study by researchers who seek to improve the method and apply it to solve various problems. One of the most significant improvements was proposed by Dilts [Dil98], which presents a way to combine the SPH approach with Moving Lea…

• Abstract

  The area of Computer Graphics has been advancing and gaining strength in the development of tools to help artists perform the work of bringing virtual characters to life. In recent years, the entertainment industry has brought high demand for this service in the entertainment market using 3D animations, whether for gaming or movie applications. Although distinct on technical issues, these…

• Abstract

  Physically based animation of fluids such as smoke, water, and fire provides some of the most stunning visuals in computer graphics being vastly used on entertainment industry. However, several phenomena have not yet been well approached and their formulations are still focus of intense research on other fields, such as Physics and Civil Engineering. That is the case of debris flow, whose…

• Abstract

  We are facing a technological moment in which the ability to acquire, transmit, store and analyze data grows amazingly. When properly acquired, integrated and analyzed, the great volume of data generated daily can lead to a better understanding of phenomena related to urban life, social networks, agricultural activities, among others.In this project, we intend to analyze, process, and dis…

• Abstract

  In the current project, we explore operators from mathematical morphology for the visual analytics of data represented using digital structures, such as graphs. This is an original approach, proved well suited for georeferenced information, with preliminary results already published. For this internship, we focus on georeferenced urban data. The framework of mathematical morphology offers…

• Abstract

  Geometric modeling involving implicit objects is a topic of intense research in Computer Graphics. Obtaining efficient techniques for representing these objects receives even more attention in applications that demand huge computation, such as generating a free surface during a fluid flow simulation. Implicit surfaces are a subset of implicit objects, usually approximated by triangular me…
