◆ DuplicateSurface()

ON_Surface* ON_SurfaceProxy::DuplicateSurface ( ) const

Description: Get a duplicate of the surface. Returns: A duplicate of the surface.
Remarks: The caller must delete the returned surface. For non-ON_SurfaceProxy objects, this simply duplicates the surface using ON_Object::Duplicate. For ON_SurfaceProxy objects, this duplicates the actual proxy surface geometry and, if necessary, transposes the result to that the returned surfaces's parameterization and locus match the proxy surface's.

		double	cos_angle_tolerance = `ON_DEFAULT_ANGLE_TOLERANCE_COSINE`,
		double	curvature_tolerance = `ON_SQRT_EPSILON`
	)		const

overridevirtual

Description: Search for a derivatitive, tangent, or curvature discontinuity. Parameters: dir - [in] If 0, then "u" parameter is checked. If 1, then the "v" parameter is checked. c - [in] type of continity to test for. t0 - [in] Search begins at t0. If there is a discontinuity at t0, it will be ignored. This makes it possible to repeatedly call GetNextDiscontinuity and step through the discontinuities. t1 - [in] (t0 != t1) If there is a discontinuity at t1 is will be ingored unless c is a locus discontinuity type and t1 is at the start or end of the curve. t - [out] if a discontinuity is found, then *t reports the parameter at the discontinuity. hint - [in/out] if GetNextDiscontinuity will be called repeatedly, passing a "hint" with initial value *hint=0 will increase the speed of the search.
dtype - [out] if not nullptr, *dtype reports the kind of discontinuity found at *t. A value of 1 means the first derivative or unit tangent was discontinuous. A value of 2 means the second derivative or curvature was discontinuous. A value of 0 means teh curve is not closed, a locus discontinuity test was applied, and t1 is at the start of end of the curve. cos_angle_tolerance - [in] default = cos(1 degree) Used only when c is ON::continuity::G1_continuous or ON::continuity::G2_continuous. If the cosine of the angle between two tangent vectors is <= cos_angle_tolerance, then a G1 discontinuity is reported. curvature_tolerance - [in] (default = ON_SQRT_EPSILON) Used only when c is ON::continuity::G2_continuous. If K0 and K1 are curvatures evaluated from above and below and |K0 - K1| > curvature_tolerance, then a curvature discontinuity is reported. Returns: Parametric continuity tests c = (C0_continuous, ..., G2_continuous):

true if a parametric discontinuity was found strictly between t0 and t1. Note well that all curves are parametrically continuous at the ends of their domains.

Locus continuity tests c = (C0_locus_continuous, ...,G2_locus_continuous):

true if a locus discontinuity was found strictly between t0 and t1 or at t1 is the at the end of a curve. Note well that all open curves (IsClosed()=false) are locus discontinuous at the ends of their domains. All closed curves (IsClosed()=true) are at least C0_locus_continuous at the ends of their domains.

◆ GetNurbForm()

int ON_SurfaceProxy::GetNurbForm	(	ON_NurbsSurface &	nurbs_surface,
		double	tolerance = `0.0`
	)		const

overridevirtual

Description: Get a NURBS surface representation of this surface. Parameters: nurbs_surface - [out] NURBS representation returned here tolerance - [in] tolerance to use when creating NURBS representation. s_subdomain - [in] if not nullptr, then the NURBS representation for this portion of the surface is returned. t_subdomain - [in] if not nullptr, then the NURBS representation for this portion of the surface is returned. Returns: 0 unable to create NURBS representation with desired accuracy. 1 success - returned NURBS parameterization matches the surface's to wthe desired accuracy 2 success - returned NURBS point locus matches the surface's to the desired accuracy and the domain of the NURBS surface is correct. On However, This surface's parameterization and the NURBS surface parameterization may not match to the desired accuracy. This situation happens when getting NURBS representations of surfaces that have a transendental parameterization like spheres, cylinders, and cones. Remarks: This is a low-level virtual function. If you do not need the parameterization information provided by the return code, then ON_Surface::NurbsSurface may be easier to use. See Also: ON_Surface::NurbsSurface

Parameters

nurbs_surface returns 0: unable to create NURBS representation with desired accuracy. 1: success - returned NURBS parameterization matches the surface's to wthe desired accuracy 2: success - returned NURBS point locus matches the surfaces's to the desired accuracy but, on the interior of the surface's domain, the surface's parameterization and the NURBS parameterization may not match to the desired accuracy.
