OCC.Hermit module¶
This is used to reparameterize Rational BSplineCurves so that we can concatenate them later tobuild C1 Curves It builds and 1D-reparameterizingfunction starting from an Hermite interpolation andadding knots and modifying poles of the 1D BSplineobtained that way. The goal is to build a(u) so thatif we consider a BSpline curveN(u)f(u) = -D(u)the function a(u)D(u) has value 1 at the umin and umaxand has 0.0e0 derivative value a umin and umax.The details of the computation occuring in this packagecan be found by reading :’ Etude sur la concatenation de NURBS en vue dubalayage de surfaces’ PFE n S85 Ensam Lille
