Hallo

First, please excuse my bad english.

I am currently making a Java3D game. In this game thera are missles from which I know the start point, the endpoint and the angle at the start point. In a physics book I found a fromula to calculate the flight path. But in some Java3D tutorials I read something about splines which should be more efficient than calculating the current position of the missile with the physic formula.

Currently I am confused about this splines. For what I understand I need some points and a spline interpolates the points between the points I know. Can I just calculate some points of the flight path with the formula and then interpolate the flight path with a spline function?
