Template Parameters

TheCurve	the curve type
TheCurveTool	the curve tool providing curve operations
ThePOnC	the point-on-curve type
ThePoint	the point type (gp_Pnt or gp_Pnt2d)

Among a set of points {C(ui), i=1,NbU}, locate the point P=C(uj) such that: distance(P,C) = Min{distance(P,C(ui))} The search is done between theUmin and theUsup.

Parameters

theP	the target point
theC	the curve to sample
theNbU	the number of sample points
theUmin	the minimum parameter value
theUsup	the maximum parameter value
thePapp	the result point on curve
