We present a technique that allows knowledge-assisted interactive visualization and segmentation of geologic surfaces. Our method employs domain knowledge about the structure and topology of geologic features in seismic data in order to steer dynamic surfaces into those features. Specialized attributes guide evolving surfaces by adapting to the known shape of geologic features. Geometric, topological, and geologic information help steer growth and can be rendered on the evolving surface, which allows knowledge to be inferred during the process. Our technique is implemented in a 3-D visualization environment that contains domain information about geologic features in seismic data and allows users to interactively steer segmentations based on visual sources of information and knowledge. Results from a user study are presented that show the ability of this technique to transfer domain knowledge to non-experts, which allows for intuitive segmentation of geologic features.
