A translator must provide: no_curves, curve_idx, gap_vert_info.

A translator may provide: def_approx.

def_approx is the default approximation for curve segments which do not have their own approximation defined.

no_curves specifies the total number of curves used by this space curve.

curve_idx is the index of the first curve in the curve list anchored in the object that is used for this space curve. This is the first of no_curves consecutive curves to use.

gap_vert_info describes the layout and size of the vertices to create during tessellation. The boxes created during tessellation will get a copy of this vertex info structure.
