1. Numerical fundamentals and interactive computer graphics system for the nonlinear analysis of planar frames
Abstract Recent scientific and computational advances have facilitated the analysis of slender structural systems subject to instability. With the employment of more sophisticated numerical tools and algorithms, it is possible to accurately determine the critical points (limit and bifurcation loads) as well as the post-critical behavior of the structural sys

5. Aceleração da deformação interativa de corpos sólidos usando GPU / GPU acceleration for interactive solid bodies deformation
Aplicativos que visam simular o comportamento físico de corpos deformáveis são importantes ferramentas científicas, também exploradas em jogos e animações computacionais. O primeiro passo para fazer uma simulação é modelar o corpo que se deseja simular, e quanto mais preciso o modelo, maior será o conjunto de dados gerados. Para gerar gráficos co

10. Numerical solutions to a cloth model based on the Cosserat surface / Soluções numericas em um modelo de tecidos baseado na superficie de Cosserat
Currently, physics-based models are frequently used for cloth simulations. There are basically two approaches: particle mechanics and continuum mechanics. The particle mechanics is at the present time the most widely used method, having some advantages like an easy formulation and a high performance. The continuum mechanics is regarded as being a more precis

11. Eficiência e precisão no cálculo de iluminação por radiosidade com GPUs
This work consists of a study about the global illumination model known as radiosity, in an effort to achieve an efficient implementation on modern hardware. Radiosity is a classic and very important method in computer graphics. It is the first proposed method to achieve photo-realism as it considers interactions among the objects of the scene. As the method

12. Proposta e implementação de uma interface para motores de jogos interativa e centrada no usuário. / Proposal and implementation of an interactive user-centered interface for game engines.
Game engines are tools to aid the development of computer and video games through software reuse. Once born in a technological environment, present game engines, either commercial or not, are normally worried more about the number of implemented features than usability issues. These characteristics may extend the period of learning-time. To address the goal
