UgSpline definition

[steveGal]

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 &quot;magnitude&quot; 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
