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.

Description: Get the parameters of the point on the surface that is closest to P. Parameters: P - [in] test point s - [out] t - [out] (*s,*t) = parameters of the surface point that is closest to P. maximum_distance = 0.0 - [in] optional upper bound on the distance from P to the surface. If you are only interested in finding a point Q on the surface when P.DistanceTo(Q) < maximum_distance, then set maximum_distance to that value. sdomain = 0 - [in] optional domain restriction tdomain = 0 - [in] optional domain restriction Returns: True if successful. If false, the values of *s and *t are undefined. See Also: ON_Surface::GetLocalClosestPoint.

) const
overridevirtual

Find parameters of the point on a surface that is locally closest to the test_point. The search for a local close point starts at seed parameters. If a sub_domain parameter is not nullptr, then the search is restricted to the specified portion of the surface.

true if returned if the search is successful. false is returned if the search fails.

Reimplemented from ON_Surface.

◆ GetNextDiscontinuity()

bool ON_SurfaceProxy::GetNextDiscontinuity ( int  dir,
ON::continuity  c,
double  t0,
double  t1,
double *  t,
int *  hint = nullptr,
int *  dtype = nullptr,
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

overridevirtual

Description: Tests an object to see if its data members are correctly initialized. Parameters: text_log - [in] if the object is not valid and text_log is not nullptr, then a brief englis description of the reason the object is not valid is appened to the log. The information appended to text_log is suitable for low-level debugging purposes by programmers and is not intended to be useful as a high level user interface tool. Returns: @untitled table true object is valid false object is invalid, uninitialized, etc.

) const
overridevirtual

Description: Offset surface. Parameters: offset_distance - [in] offset distance tolerance - [in] Some surfaces do not have an exact offset that can be represented using the same class of surface definition. In that case, the tolerance specifies the desired accuracy. max_deviation - [out] If this parameter is not nullptr, the maximum deviation from the returned offset to the true offset is returned here. This deviation is zero except for cases where an exact offset cannot be computed using the same class of surface definition. Remarks: Overrides virtual ON_Surface::Offset. Returns: Offset surface.

Description: Transforms the object.

Parameters: xform - [in] transformation to apply to object. If xform.IsSimilarity() is zero, then you may want to call MakeSquishy() before calling Transform.

Remarks: When overriding this function, be sure to include a call to ON_Object::TransformUserData() which takes care of transforming any ON_UserData that may be attached to the object.

See Also: ON_Geometry::IsDeformable();

Remarks: Classes derived from ON_Geometry should call ON_Geometry::Transform() to handle user data transformations and then transform their definition.
