Returns: table 0 failure 1 success - parameterization is exact 2 success - parameterization is not exact Remarks: The ruling parameter is the second surface parameter and it is in the interval [0,1]. The true ruled surface has parameterization srf(s,t) = (1.0-t)*curveA(s) + t*curveB(s). The returned NURBS surface has parameterization srf(s,t) = (1.0-t)*nurbs_curveA(s) + t*nurbs_curveB(s), where nurbs_curveX is the NURBS form of curveX. If the parameterization of nurbs_curveX does not match the parameterization of curveX, then 2 is returned. </p>

<p>Description: Expert user function to get a pointer to control vertex memory. If you are not an expert user, please use ON_NurbsSurface::GetCV( ON_3dPoint& ) or ON_NurbsSurface::GetCV( ON_4dPoint& ). Parameters: i - [in] (0 <= i < m_cv_count[0]) j - [in] (0 <= j < m_cv_count[1]) Returns: Pointer to control vertex. Remarks: If the NURBS surface is rational, the format of the returned array is a homogeneos rational point with length m_dim+1. If the NURBS surface is not rational, the format of the returned array is a nonrational euclidean point with length m_dim.

<p>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):</p>
|
|
<p>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.</p>
|
|
<p>Locus continuity tests c = (C0_locus_continuous, ...,G2_locus_continuous):</p>
|
|
<p>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 (<a class="el" href="../../de/ddc/class_o_n___nurbs_surface.html#a79f03807b92800d7fdb85cd53ab275ef">IsClosed()</a>=false) are locus discontinuous at the ends of their domains. All closed curves (<a class="el" href="../../de/ddc/class_o_n___nurbs_surface.html#a79f03807b92800d7fdb85cd53ab275ef">IsClosed()</a>=true) are at least C0_locus_continuous at the ends of their domains. </p>

<p>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.

<p>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. Returns: Offset surface. </p>
