Detailed Description


: Hung NGUYEN , INRIA 2013 - 2014.

: From IGES - page 191 (this number is in pdf file, NOT the page in book):

  • The Curve on a Parametric Surface Entity associates a given curve with a surface and identifies the curve as lying on the surface. If S is a regular parameterized surface whose domain is a rectangle defined by D = {( u,v )| u1 <= u <= u2 and v1 <= v <= v2 )} Let B = B(t) be a curve defined by B(t) = (u(t), v(t)) for a <= t <= b, taking its values in D. A curve Cc(t) on the surface S(u, v) is the composition of two mappings, S and B, defined as: Cc(t) = S o B(t) = (x(u(t),v(t)),y(u(t),v(t)),z(u(t),v(t))) : A curve on a surface may have been created in one of a number of various ways: " 1. as the projection on the surface of a given curve in model space in a prescribed way, for example, parallel to a given fixed vector

    1. as the intersection of two given surfaces
    2. by a prescribed functional relation between the surface parameters u and v
    3. by a special curve, such as a geodesic, emanating from a given point in a certain direction, a principal curve (line of curvature) emanating from a certain point, an asymptotic curve emanating from a certain point, an isoparametric curve for a given value, or any other kind of

      special curve. " (IGES - page 191).

    There are an important variable in this class, way_create_curve. So, be careful when use the methods set_way_create_curve(). Because it will decide what data will be used. See this information below:

value of way_create_curve | Methods | Variable will be used 0 | Unspecified | None of them 1 | Projection of a givencurve on the surface | sup_dir, sup_curve 2 | Intersection of two surfaces | sup_surface

3 | Isoparametric curve | value_u,value_v


  • in the column 3, others var will be set NULL.
  • sup_dir = support direction, sup_curve = support curve, sup_surface = support surface.
  • Read carefully about the definition to understand well.
  • When you want to change the way to describe the curve, I recommend to create the new object.
  • At the moment (when I write this line), there are no way to exchange between the way of describing the
