Structural -> Gaussian and Mean Curvatures

Attribute Description:

The Gaussian and Mean curvatures are critical volumes for the derivation of other curvature attributes.

Interpretation Use:

Gaussian curvatures have been correlated to fracture systems.  Gaussian and mean curvatures often work together to identify local shapes since each attribute cannot differentiate the shapes alone. However, the two volumes are not particularly useful individually for visual interpretation.

Recommended Color Palette:

Colorbar for curvatures often includes two color themes such as blue and red or black and red to mark the anomalies. The less anomalous value along the zero value is marked by white or being transparent in the middle.
