In the oil industry, clear and unambiguous 3D flow visualization techniques are very important to inspect the results of numerical simulation of black-oil reservoir models. In this paper, we revisit the use of line integral convolution (LIC) for imaging 3D vector fields on arbitrary surfaces and apply it to reservoir visualization. We use a GPU-based method to image the tangential component using the conventional 2D LIC in projected screen space and propose the use of color to encode the normal component. To attach the flow imaging to the 3D surfaces, avoiding image flickering while manipulating the model, we propose a simple scheme based on randomly generated texture coordinate, avoiding the use of a solid 3D texture noise. For animation, we adjust the use of filters to ensure that the animation speed varies in accordance to the field magnitude. We also explore the visualization of multiphase (oil, gas, and water) flow. Distributed software development imposes challenges because of geographical, temporal and the cultural differences in which distributed teams live in. The advances in telecommunication, media, and technology have allowed companies to develop ways to simulate physical proximity in a real-time fashion. For instance, the sharing of a real-size screen can be used to promote the feeling that people on the other side of the screen are physically co-located with those in a certain site. The adoption of tools, methods, and technologies that simulate physical proximity aims to minimize the well-known challenges faced by distributed teams. The goal of this paper is to present the experience of a multinational Brazilian company in adopting technology to simulated co-location to support their software development processes. The benefits of such simulation, such as improved communication, and challenged faced, such as infrastructure problems, are also described.
