class SplineSurface : public xlifepp::Surface #

Inheritence diagram for xlifepp::SplineSurface:

Collaboration diagram for xlifepp::SplineSurface:

definition of a SplineSurface geometry in R^3 from a Nurbs object (non uniform rational Bspline) only nurbs are available either approximation nurbs or interpolation nurbs (default when subtype is not specified)

SplineSurface constructors are based on a key-value system. Here are the available keys:

_vertices: list of control points
_spline: spline object
_spline_type: type of spline one of _C2Spline, _CatmullRomSpline, _BSpline, _BezierSpline, _Nurbs
_spline_subtype: subtype of spline, one of _SplineInterpolation, _SplineApproximation
_spline_BC: spline boundary condition, one of _naturalBC, _clampedBC, _periodicBC
_degree: degree of spline (default 3)
_nbu: number of control/interpolation points in u-direction (_Nurbs only)
_spline_parametrization: spline parametrization type, one of _xParametrization, _uniformParametrization,_chordalParametrization, _centripetalParametrization
_weights: weights of control points (for _BSpline only)
_nnodes: to define the number of nodes on the arc
_hsteps: to define the local mesh steps on the bounds
_domain_name: to define the domain name
_side_names: to define the side names
_varnames: to define the variable names for print purpose
