SPAkern Global Function bs3_surface_make_spl

bs3_surface bs3_surface_make_spl(	spline const&	`spl`,
	SPAbox const&	`reg_int`,
	double	`fit_tol`	`= 0`,
	double&	`actual_fit`	`= (double )NULL_REF`,
	SPApar_transf&	`space_mapping`	`= (SPApar_transf)NULL_REF` )

Creates a parametric surface coincident with the given spline.

Role: Creates a parametric surface coincident with the given spline over at least the portion inside the box, within the specified positional tolerance, and has its normal in the same sense.

If the actual_fit argument is supplied, it returns the actual tolerance achieved, or exact zero if this is better than system positional tolerance.

Optionally, the mapping from the old parameter bounds to the new parameter bounds can be returned by supplying the pt argument.

Effect: Changes model

Parameters:

spl: given spline.
reg_int: region of interest.
fit_tol: requested fit tolerance.
actual_fit: returns actual fit used.
space_mapping: returns parameter space mapping.
