Knowledge-Assisted Visualization and Segmentation of Geologic Features using Implicit Surfaces

Abstract

The proposed approach employs domain knowledge about the structure and topology of geologic features in seismic data to steer dynamic surfaces into those features. Specialized attributes guide evolving surfaces by adapting to the features' known shape. Geometric, topological, and geologic information can be rendered on the evolving surface, which lets the user infer knowledge during the process. The approach is implemented in a 3D visualization environment. A user study demonstrates this approach's ability to transfer domain knowledge to nonexperts. This article is part of a special issue on knowledge-assisted visualization.
