Constrained implicit geological models

Use LoopStructural when observations constrain continuous geological scalar fields. A scalar value labels an interface; it is not automatically an age, measured depth or elevation. Record the coordinate CRS, shared XYZ units, positive-Z convention, feature order and meaning of each scalar level.

A constrained planar model

This synthetic example uses metre coordinates with a nonzero origin and an asymmetric box. Its scalar field is Z - 3030 + 0.1*(X - 1050) - 0.05*(Y - 2100) in metres. Scalar observations and gradient constraints anchor both level and orientation; a single point alone cannot define a geological surface.
