Human-computer interaction has had continuous changes in recent year, with a significant improvement in touch screens and motion sensors. New sensing technologies, like Microsoft Kinect, provide a low-cost way to add interactivity with gestures and postures. The current tendency is to develop software for the web. Interactions through the Kinect can be an(More)
Since many years, global illumination algorithms find limited use on interactive applications due to the computational cost for calculating the interaction of light in an environment. A branch of the solutions consist in creating a discretized representation of the scene in order to estimate diffuse interactions from multiple light bounces in real-time. In(More)
The central pool of IPv4 addresses managed by IANA was depleted in February 2011. A similar situation will soon happen at the level of LACNIC, the local RIR for South America. Therefore, it is necessary to deploy the new version of the Internet Protocol (IPv6) which dramatically expands the address space. However, this deployment must be done gradually and(More)
Volume rendering is an important area of study in computer graphics, due to its application in areas such as medicine, physic simulations, oil and gas industries, and others. The main used method nowadays for volume rendering is ray casting. Nevertheless, there are a variety of parallel APIs that can be used to implement it. Thus, it is important to(More)
