Many games and other interactive virtual environments are known for their focus in rendering natural phenomena, such as accurate visuals and physics, in the most believable manner. Several advances in the aforementioned fields took place during the last decade but, unfortunately, this effort has not been reflected in libraries for spatial audio. These(More)
The scattering of acoustic waves in non-homogeneous media has been of practical interest for the petroleum industry, mainly in the determination of new oil deposits. A family of computational models that represent this phenomenon is based on finite difference methods. The simulation of these phenomena demands a high computational cost. In this work we(More)
This work presents a probabilistic model for the microscopic simulation of traffic roads based on Nagel-Schreckenberg’s model. Each driver’s behavior is described through the combination of a continuous probability function with an anticipatory feature that leads to a counter flow velocity tunning. The simulations developed and described herein give rise to(More)
The need for fast solution of large scientific and industrial problems has long motivated the quest for improvements both in software as well as in hardware, since the inception of computing tools. In this context, vectorization, parallelization of tasks have been important strategies for the improvement of hardware efficiency during the last decades.(More)
Most games and other interactive virtual environments focus on rendering natural phenomena in the most believable manner by using accurate visuals and physics. However, not much effort has been put into accounting for the physics of sound. The simulation of the real behavior of sound through an environment, when considering the speed of sound, reflection,(More)
This paper presents the time complexity of two algorithms that update space-filling curves of adaptively refined domains. The Modified Hilbert (space-filling) Curve was proposed to traverse square-shaped adaptive-refined meshes. Whereas, the Sierpiński-like (space-filling) Curve was proposed in order to traverse triangular-shaped adaptive-refined meshes.(More)
