GeoMesh

The research project

GeoMesh is an ongoing master's project developed through a partnership between UFF and Petrobras, where I work as a research fellow. The system digitally reconstructs rock cores, samples taken from oil wells for geological analysis before extraction, and makes them available for three-dimensional inspection.

The work is applied research for Petrobras geologists rather than a visualization demo. Because the project is closed, I can describe its goals and public technical scope but not private implementation details.

Reconstruction and viewers

I research new reconstruction methods and implement or adapt existing approaches, including NeRF, Gaussian Splatting and open-source multi-view stereo. My responsibilities cover the path from reconstructing the physical sample to presenting the result in an interface that geologists can inspect.

The system's core is written in C++, with viewers built in both Unity and Unreal Engine. Some versions also support virtual reality, allowing the reconstructed core to be explored spatially instead of only on a flat display.

Geological fidelity

A useful reconstruction needs enough detail for geological analysis, not only a convincing surface image. That requirement makes fidelity, processing cost and real-time inspection part of the same technical problem.

I compare reconstruction families and adapt them to rock-core data, then connect their output to C++, Unity, Unreal and VR visualization paths. The work also requires translating requirements between computing and geology so the viewer serves the people who analyze the samples.
