Thus its interpolation attribute shall be "linear". The default GenericCurve::parameterization = c(s) is: (L : Distance) = endParam startParam c(s) = ControlPoint[1]+((s-startParam)/L)*(ControlPoint[2]-ControlPoint[1]) Any other point in the controlPoint array must fall on this line. The control points of a LineSegment shall all lie on the straight line between its start point and end point. Between these two points, other positions may be interpolated linearly. NOTE The linear interpolation, given using a constructive parameter t, 0 ? t ? 1.0, where c(o) = c.startPoint() and c(1)=c.endPoint(), is: c(t) = c(0)(1-t) + c(1)t @author Jackson Roehrig & Sanjay Jena @source $URL$
