A reservoir engineer’s job is to understand and predict what cannot be seen or touched. To this end, a number of indirect tools and measurements are required, involving considerable uncertainty. Gather information about the reservoir is a costly and time consuming task. A reservoir model is build to converge all the available data and extrapolate over a 3D geological model, in order to characterize the subsurface environment to be used in numerical simulators. It guides the planning and the production of the field in its whole lifetime. In the Oil and Gas industry, processing and visualizing 3D models is of paramount importance for making exploration and production decisions. To overcome this challenge, I have implemented an interactive Cutaway method, strongly relying on screen-space GPU techniques, specially designed for inspecting 3D reservoir models represented as corner-point grids, the industry’s standard.

The Digital Bamberg project was a joint collaboration between the Computer Graphics Lab at PESC/UFRJ, and the Museum of Astronomy and Related Sciences (MAST). It combined the challenges of creating a digital replica of a scientific instrument, that, at the same time, is part of the museum collection and, hence, is treated as an historical artifact. In the project, I have assisted development and design software and algorithms for the 3D digitization process, which include the acquisition of the 3D geometry, by a laser scanner, and the registration of high quality images, acquired by a professional DSLR camera, of a historic scientific instrument. The process of "clue" all the high quality images in the final scanner model generate most of the output research of the project, that involve image processing and texture registration.

In this project, I have Implemented the software prototype ReactBar. A collaborative effort in conjunction with designer, as part of the workshop of Interactive Media and Natural Interfaces promoted by Visgraf at IMPA. The workshop focused on topics related with recent advances in tangible user interfaces (TUI), multitouch interaction, computer graphics, image processing, sound synthesis and new authoring environments. The idea of Reactbar is to use multitouch interaction and tangible interface for entertainment in public spaces, exploring the concept of social networking. It has a simple and intuitive interface, in a fun use experience. It promotes a real interaction among users, starting it in a virtual way.
