UgSpline definition

UgSpline definition

UgSpline definition

(OP)
I need to control a spline exactly according to a given spline definition (location, slope and curvature)

I'm doing this in UgOpenPP, using the UgSpline::create(vector<ThruPoint>) where the ThruPoint I'm using is defined giving using the slope and curvature options (well I've set the curvature to the option ThruPoint::CurvatureTypeNone) on a 3rd order spline, but I'm not sure how the definition of "magnitude" of the slope comes into play. Does this affect the curvature?

Does anyone have the mathematical definitions used so I can figure out what I want?

Thanks,
Steve
