◆ DuplicateSurface()
|
overridevirtual |
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.

◆ GetClosestPoint()
|
overridevirtual |
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.
Reimplemented from ON_Surface.
◆ GetLocalClosestPoint()
|
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()
|
overridevirtual |
Description: Search for a derivative, 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 continuity 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 ignored 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 the 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.
Reimplemented from ON_Surface.
◆ GetNurbForm()
|
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 the 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 transcendental 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

◆ HasNurbForm()
|
overridevirtual |
Description: Is there a NURBS surface representation of this surface. Parameters: Returns: 0 unable to create NURBS representation with desired accuracy. 1 success - NURBS parameterization matches the surface's 2 success - NURBS point locus matches the surface's and the domain of the NURBS surface is correct.
However, This surface's parameterization and the NURBS surface parameterization may not match. This situation happens when getting NURBS representations of surfaces that have a transcendental parameterization like spheres, cylinders, and cones. Remarks: This is a low-level virtual function.

◆ IsContinuous()
|
overridevirtual |
Description: Test continuity at a surface parameter value. Parameters: c - [in] continuity to test for s - [in] surface parameter to test t - [in] surface parameter to test hint - [in] evaluation hint point_tolerance - [in] if the distance between two points is greater than point_tolerance, then the surface is not C0. d1_tolerance - [in] if the difference between two first derivatives is greater than d1_tolerance, then the surface is not C1. d2_tolerance - [in] if the difference between two second derivatives is greater than d2_tolerance, then the surface is not C2. 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 normal 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: true if the surface has at least the c type continuity at the parameter t. Remarks: Overrides virtual ON_Surface::IsContinuous

Reimplemented from ON_Geometry.
◆ Offset()
|
overridevirtual |
Description: Offset surface.

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.

overridevirtual |
Description: Pull a 3d curve back to the surface's parameter space. Parameters: curve_3d - [in] a 3d curve tolerance - [in] the maximum acceptable 3d distance between from surface(curve_2d(t)) to the locus of points on the surface that are closest to curve_3d. curve_3d_subdomain - [in] optional subdomain for curve_3d start_uv - [in] optional starting point (if known) end_uv - [in] optional ending point (if known) rc - [out] if not 0 on input, points to an ON_FitResult with the following value - ON_FitResult::in_tolerance if result is in tolerance ON_FitResult::not_in_tolerance if result is not in tolerance ON_FitResult::unknown if no result or it could not be determined if the result was in tolerance. Returns: 2d curve. See Also: ON_Surface::IsoCurve ON_Surface::Pushup

◆ Pushup()
|
overridevirtual |
Description: Compute a 3d curve that is the composite of a 2d curve and the surface map. Parameters: curve_2d - [in] a 2d curve whose image is in the surface's domain. tolerance - [in] the maximum acceptable distance from the returned 3d curve to the image of curve_2d on the surface. curve_2d_subdomain - [in] optional subdomain for curve_2d rc - [out] if not 0 on input, points to an ON_FitResult with the following value - ON_FitResult::in_tolerance if result is in tolerance ON_FitResult::not_in_tolerance if result is not in tolerance ON_FitResult::unknown if no result or it could not be determined if the result was in tolerance. Returns: 3d curve. See Also: ON_Surface::IsoCurve ON_Surface::Pullback

◆ Read()
|
overridevirtual |
Description: Low level archive writing tool used by ON_BinaryArchive::ReadObject(). Parameters: binary_archive - archive to read from Returns: Returns true if the read is successful. Remarks: Use ON_BinaryArchive::ReadObject() to read objects. This Read() function should read the objects definition back into its data members.
The default implementation of this virtual function returns false and does nothing.

number of smooth spans in curve
Implements ON_Surface.
◆ Transform()
|
overridevirtual |
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.

Implements ON_Surface.
◆ Write()
|
overridevirtual |
Description: Low level archive writing tool used by ON_BinaryArchive::WriteObject(). Parameters: binary_archive - archive to write to Returns: Returns true if the write is successful. Remarks: Use ON_BinaryArchive::WriteObject() to write objects. This Write() function should just write the specific definition of this object. It should not write and any chunk typecode or length information.
The default implementation of this virtual function returns false and does nothing.
