# Modelling folds using structural geology
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
# The following section will describe how the fold axis, fold axial
# surface and fold vergence can be used to help constrain the shape of the
# folded surface. To do this we need to build a fold frame which is
# curvilinear coordinate system based around the fold axis and the fold
# axial surface.
#
# There are three coordinates to the fold frame: \* coordinate 0 is the
# axial surface of the fold and is parallel to the axial foliation \*
# then interpolated by first restoring the observations by combining the
# fault frame and an expected displacement model.
